+.SH "NOTES"
+.PP
+The recommended syntax for referencing an ordered\-set aggregate is to write

+between the direct and aggregated argument specifications, in the same style as in
+\fBCREATE AGGREGATE\fR\&. However, it will also work to omit
+ORDER BY

+.SH "NOTES"
+.PP
+When a collation object is created, the provider\-specific version of the collation is recorded in the system catalog\&. When the collation is used, the current version is checked against the recorded version, and a warning is issued when there is a mismatch, for example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+WARNING:  collation "xx\-x\-icu" has version mismatch
+DETAIL:  The collation in the database was created using version 1\&.2\&.3\&.4, but the operating system provides version 2\&.3\&.4\&.5\&.
+HINT:  Rebuild all objects affected by this collation and run ALTER COLLATION pg_catalog\&."xx\-x\-icu" REFRESH VERSION, or build PostgreSQL with the right library version\&.
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+A change in collation definitions can lead to corrupt indexes and other problems because the database system relies on stored objects having a certain sort order\&. Generally, this should be avoided, but it can happen in legitimate circumstances, such as when upgrading the operating system to a new major version or when using
+\fBpg_upgrade\fR
+to upgrade to server binaries linked with a newer version of ICU\&. When this happens, all objects depending on the collation should be rebuilt, for example, using
+\fBREINDEX\fR\&. When that is done, the collation version can be refreshed using the command
+ALTER COLLATION \&.\&.\&. REFRESH VERSION\&. This will update the system catalog to record the current collation version and will make the warning go away\&. Note that this does not actually check whether all affected objects have been rebuilt correctly\&.
+.PP
+When using collations provided by
+libc, version information is recorded on systems using the GNU C library (most Linux systems), FreeBSD and Windows\&. When using collations provided by ICU, the version information is provided by the ICU library and is available on all platforms\&.

+.PP
+When using the GNU C library for collations, the C library\*(Aqs version is used as a proxy for the collation version\&. Many Linux distributions change collation definitions only when upgrading the C library, but this approach is imperfect as maintainers are free to back\-port newer collation definitions to older C library releases\&.
+.PP
+When using Windows for collations, version information is only available for collations defined with BCP 47 language tags such as
+en\-US\&.
+.sp .5v
+.RE
+.PP
+For the database default collation, there is an analogous command

+.SH "DESCRIPTION"
+.PP
+\fBALTER DEFAULT PRIVILEGES\fR
+allows you to set the privileges that will be applied to objects created in the future\&. (It does not affect privileges assigned to already\-existing objects\&.) Currently, only the privileges for schemas, tables (including views and foreign tables), sequences, functions, and types (including domains) can be altered\&. For this command, functions include aggregates and procedures\&. The words
+FUNCTIONS
+and
+ROUTINES
+are equivalent in this command\&. (ROUTINES
+is preferred going forward as the standard term for functions and procedures taken together\&. In earlier PostgreSQL releases, only the word
+FUNCTIONS
+was allowed\&. It is not possible to set default privileges for functions and procedures separately\&.)
+.PP
+You can change default privileges only for objects that will be created by yourself or by roles that you are a member of\&. The privileges can be set globally (i\&.e\&., for all objects created in the current database), or just for objects created in specified schemas\&.
+.PP
+As explained in
+Section\ \&5.7, the default privileges for any object type normally grant all grantable permissions to the object owner, and may grant some privileges to
+PUBLIC
+as well\&. However, this behavior can be changed by altering the global default privileges with
+\fBALTER DEFAULT PRIVILEGES\fR\&.
+.PP
+Default privileges that are specified per\-schema are added to whatever the global default privileges are for the particular object type\&. This means you cannot revoke privileges per\-schema if they are granted globally (either by default, or according to a previous
+\fBALTER DEFAULT PRIVILEGES\fR
+command that did not specify a schema)\&. Per\-schema
+REVOKE
+is only useful to reverse the effects of a previous per\-schema
+GRANT\&.
+.SS "Parameters"
+.PP
+\fItarget_role\fR
+.RS 4
+The name of an existing role of which the current role is a member\&. If
+FOR ROLE
+is omitted, the current role is assumed\&.
+.RE
+.PP
+\fIschema_name\fR
+.RS 4
+The name of an existing schema\&. If specified, the default privileges are altered for objects later created in that schema\&. If
+IN SCHEMA
+is omitted, the global default privileges are altered\&.
+IN SCHEMA
+is not allowed when setting privileges for schemas, since schemas can\*(Aqt be nested\&.
+.RE
+.PP
+\fIrole_name\fR
+.RS 4
+The name of an existing role to grant or revoke privileges for\&. This parameter, and all the other parameters in
+\fIabbreviated_grant_or_revoke\fR, act as described under
+\fBGRANT\fR(7)
+or
+\fBREVOKE\fR(7), except that one is setting permissions for a whole class of objects rather than specific named objects\&.
+.RE
+.SH "NOTES"
+.PP
+Use
+\fBpsql\fR(1)\*(Aqs
+\fB\eddp\fR
+command to obtain information about existing assignments of default privileges\&. The meaning of the privilege display is the same as explained for
+\fB\edp\fR
+in
+Section\ \&5.7\&.
+.PP
+If you wish to drop a role for which the default privileges have been altered, it is necessary to reverse the changes in its default privileges or use
+\fBDROP OWNED BY\fR
+to get rid of the default privileges entry for the role\&.
+.SH "EXAMPLES"
+.PP
+Grant SELECT privilege to everyone for all tables (and views) you subsequently create in schema
+myschema, and allow role
+webuser
+to INSERT into them too:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ALTER DEFAULT PRIVILEGES IN SCHEMA myschema GRANT SELECT ON TABLES TO PUBLIC;
+ALTER DEFAULT PRIVILEGES IN SCHEMA myschema GRANT INSERT ON TABLES TO webuser;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Undo the above, so that subsequently\-created tables won\*(Aqt have any more permissions than normal:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ALTER DEFAULT PRIVILEGES IN SCHEMA myschema REVOKE SELECT ON TABLES FROM PUBLIC;
+ALTER DEFAULT PRIVILEGES IN SCHEMA myschema REVOKE INSERT ON TABLES FROM webuser;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Remove the public EXECUTE permission that is normally granted on functions, for all functions subsequently created by role
+admin:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ALTER DEFAULT PRIVILEGES FOR ROLE admin REVOKE EXECUTE ON FUNCTIONS FROM PUBLIC;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Note however that you
+\fIcannot\fR
+accomplish that effect with a command limited to a single schema\&. This command has no effect, unless it is undoing a matching
+GRANT:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ALTER DEFAULT PRIVILEGES IN SCHEMA public REVOKE EXECUTE ON FUNCTIONS FROM PUBLIC;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+That\*(Aqs because per\-schema default privileges can only add privileges to the global setting, not remove privileges granted by it\&.
+.SH "COMPATIBILITY"
+.PP
+There is no
+\fBALTER DEFAULT PRIVILEGES\fR
+statement in the SQL standard\&.
+.SH "SEE ALSO"

+\fBALTER DOMAIN\fR

+.RE
+.PP
+SET/DROP NOT NULL
+.RS 4
+These forms change whether a domain is marked to allow NULL values or to reject NULL values\&. You can only
+SET NOT NULL
+when the columns using the domain contain no null values\&.
+.RE
+.PP
+ADD \fIdomain_constraint\fR [ NOT VALID ]
+.RS 4
+This form adds a new constraint to a domain using the same syntax as
+\fBCREATE DOMAIN\fR\&. When a new constraint is added to a domain, all columns using that domain will be checked against the newly added constraint\&. These checks can be suppressed by adding the new constraint using the
+NOT VALID
+option; the constraint can later be made valid using
+\fBALTER DOMAIN \&.\&.\&. VALIDATE CONSTRAINT\fR\&. Newly inserted or updated rows are always checked against all constraints, even those marked
+NOT VALID\&.
+NOT VALID
+is only accepted for
+CHECK
+constraints\&.
+.RE
+.PP
+DROP CONSTRAINT [ IF EXISTS ]
+.RS 4
+This form drops constraints on a domain\&. If
+IF EXISTS
+is specified and the constraint does not exist, no error is thrown\&. In this case a notice is issued instead\&.
+.RE
+.PP
+RENAME CONSTRAINT
+.RS 4
+This form changes the name of a constraint on a domain\&.
+.RE
+.PP
+VALIDATE CONSTRAINT
+.RS 4
+This form validates a constraint previously added as
+NOT VALID, that is, it verifies that all values in table columns of the domain type satisfy the specified constraint\&.
+.RE
+.PP
+OWNER
+.RS 4
+This form changes the owner of the domain to the specified user\&.
+.RE
+.PP
+RENAME
+.RS 4
+This form changes the name of the domain\&.
+.RE
+.PP
+SET SCHEMA
+.RS 4
+This form changes the schema of the domain\&. Any constraints associated with the domain are moved into the new schema as well\&.
+.RE
+.PP
+You must own the domain to use
+\fBALTER DOMAIN\fR\&. To change the schema of a domain, you must also have
+CREATE
+privilege on the new schema\&. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have
+CREATE
+privilege on the domain\*(Aqs schema\&. (These restrictions enforce that altering the owner doesn\*(Aqt do anything you couldn\*(Aqt do by dropping and recreating the domain\&. However, a superuser can alter ownership of any domain anyway\&.)
+.SH "PARAMETERS"
+.PP
+.PP
+\fIname\fR
+.RS 4
+The name (possibly schema\-qualified) of an existing domain to alter\&.
+.RE
+.PP
+\fIdomain_constraint\fR
+.RS 4
+New domain constraint for the domain\&.
+.RE
+.PP
+\fIconstraint_name\fR
+.RS 4
+Name of an existing constraint to drop or rename\&.
+.RE
+.PP
+NOT VALID
+.RS 4
+Do not verify existing stored data for constraint validity\&.
+.RE
+.PP
+CASCADE
+.RS 4
+Automatically drop objects that depend on the constraint, and in turn all objects that depend on those objects (see
+Section\ \&5.14)\&.
+.RE
+.PP
+RESTRICT
+.RS 4
+Refuse to drop the constraint if there are any dependent objects\&. This is the default behavior\&.
+.RE
+.PP
+\fInew_name\fR
+.RS 4
+The new name for the domain\&.
+.RE
+.PP
+\fInew_constraint_name\fR
+.RS 4
+The new name for the constraint\&.
+.RE
+.PP
+\fInew_owner\fR
+.RS 4
+The user name of the new owner of the domain\&.
+.RE
+.PP
+\fInew_schema\fR
+.RS 4
+The new schema for the domain\&.
+.RE
+.SH "NOTES"
+.PP
+Although
+\fBALTER DOMAIN ADD CONSTRAINT\fR
+attempts to verify that existing stored data satisfies the new constraint, this check is not bulletproof, because the command cannot
+\(lqsee\(rq
+table rows that are newly inserted or updated and not yet committed\&. If there is a hazard that concurrent operations might insert bad data, the way to proceed is to add the constraint using the
+NOT VALID
+option, commit that command, wait until all transactions started before that commit have finished, and then issue
+\fBALTER DOMAIN VALIDATE CONSTRAINT\fR
+to search for data violating the constraint\&. This method is reliable because once the constraint is committed, all new transactions are guaranteed to enforce it against new values of the domain type\&.
+.PP
+Currently,
+\fBALTER DOMAIN ADD CONSTRAINT\fR,
+\fBALTER DOMAIN VALIDATE CONSTRAINT\fR, and
+\fBALTER DOMAIN SET NOT NULL\fR
+will fail if the named domain or any derived domain is used within a container\-type column (a composite, array, or range column) in any table in the database\&. They should eventually be improved to be able to verify the new constraint for such nested values\&.

+.SH "DESCRIPTION"
+.PP
+\fBALTER FOREIGN TABLE\fR
+changes the definition of an existing foreign table\&. There are several subforms:
+.PP
+ADD COLUMN
+.RS 4
+This form adds a new column to the foreign table, using the same syntax as
+\fBCREATE FOREIGN TABLE\fR\&. Unlike the case when adding a column to a regular table, nothing happens to the underlying storage: this action simply declares that some new column is now accessible through the foreign table\&.
+.RE
+.PP
+DROP COLUMN [ IF EXISTS ]
+.RS 4
+This form drops a column from a foreign table\&. You will need to say
+CASCADE
+if anything outside the table depends on the column; for example, views\&. If
+IF EXISTS
+is specified and the column does not exist, no error is thrown\&. In this case a notice is issued instead\&.
+.RE
+.PP
+SET DATA TYPE
+.RS 4
+This form changes the type of a column of a foreign table\&. Again, this has no effect on any underlying storage: this action simply changes the type that
+PostgreSQL
+believes the column to have\&.
+.RE
+.PP
+SET/DROP DEFAULT
+.RS 4
+These forms set or remove the default value for a column\&. Default values only apply in subsequent
+\fBINSERT\fR
+or
+\fBUPDATE\fR
+commands; they do not cause rows already in the table to change\&.
+.RE
+.PP
+SET/DROP NOT NULL
+.RS 4
+Mark a column as allowing, or not allowing, null values\&.
+.RE
+.PP
+SET STATISTICS
+.RS 4
+This form sets the per\-column statistics\-gathering target for subsequent
+\fBANALYZE\fR
+operations\&. See the similar form of
+\fBALTER TABLE\fR
+for more details\&.
+.RE
+.PP
+SET ( \fIattribute_option\fR = \fIvalue\fR [, \&.\&.\&. ] )
+.br
+RESET ( \fIattribute_option\fR [, \&.\&.\&. ] )
+.RS 4
+This form sets or resets per\-attribute options\&. See the similar form of
+\fBALTER TABLE\fR
+for more details\&.
+.RE
+.PP
+SET STORAGE
+.RS 4
+This form sets the storage mode for a column\&. See the similar form of
+\fBALTER TABLE\fR
+for more details\&. Note that the storage mode has no effect unless the table\*(Aqs foreign\-data wrapper chooses to pay attention to it\&.
+.RE
+.PP
+ADD \fItable_constraint\fR [ NOT VALID ]
+.RS 4
+This form adds a new constraint to a foreign table, using the same syntax as
+\fBCREATE FOREIGN TABLE\fR\&. Currently only
+CHECK
+constraints are supported\&.
+.sp
+Unlike the case when adding a constraint to a regular table, nothing is done to verify the constraint is correct; rather, this action simply declares that some new condition should be assumed to hold for all rows in the foreign table\&. (See the discussion in
+\fBCREATE FOREIGN TABLE\fR\&.) If the constraint is marked
+NOT VALID, then it isn\*(Aqt assumed to hold, but is only recorded for possible future use\&.
+.RE
+.PP
+VALIDATE CONSTRAINT
+.RS 4
+This form marks as valid a constraint that was previously marked as
+NOT VALID\&. No action is taken to verify the constraint, but future queries will assume that it holds\&.
+.RE
+.PP
+DROP CONSTRAINT [ IF EXISTS ]
+.RS 4
+This form drops the specified constraint on a foreign table\&. If
+IF EXISTS
+is specified and the constraint does not exist, no error is thrown\&. In this case a notice is issued instead\&.
+.RE
+.PP
+DISABLE/ENABLE [ REPLICA | ALWAYS ] TRIGGER
+.RS 4
+These forms configure the firing of trigger(s) belonging to the foreign table\&. See the similar form of
+\fBALTER TABLE\fR
+for more details\&.
+.RE
+.PP
+SET WITHOUT OIDS
+.RS 4
+Backward compatibility syntax for removing the
+oid
+system column\&. As
+oid
+system columns cannot be added anymore, this never has an effect\&.
+.RE
+.PP
+INHERIT \fIparent_table\fR
+.RS 4
+This form adds the target foreign table as a new child of the specified parent table\&. See the similar form of
+\fBALTER TABLE\fR
+for more details\&.
+.RE
+.PP
+NO INHERIT \fIparent_table\fR
+.RS 4
+This form removes the target foreign table from the list of children of the specified parent table\&.
+.RE
+.PP
+OWNER
+.RS 4
+This form changes the owner of the foreign table to the specified user\&.
+.RE
+.PP
+OPTIONS ( [ ADD | SET | DROP ] \fIoption\fR [\*(Aq\fIvalue\fR\*(Aq] [, \&.\&.\&. ] )
+.RS 4
+Change options for the foreign table or one of its columns\&.
+ADD,
+SET, and
+DROP
+specify the action to be performed\&.
+ADD
+is assumed if no operation is explicitly specified\&. Duplicate option names are not allowed (although it\*(Aqs OK for a table option and a column option to have the same name)\&. Option names and values are also validated using the foreign data wrapper library\&.
+.RE
+.PP
+RENAME
+.RS 4
+The
+RENAME
+forms change the name of a foreign table or the name of an individual column in a foreign table\&.
+.RE
+.PP
+SET SCHEMA
+.RS 4
+This form moves the foreign table into another schema\&.
+.RE
+.PP
+All the actions except
+RENAME
+and
+SET SCHEMA
+can be combined into a list of multiple alterations to apply in parallel\&. For example, it is possible to add several columns and/or alter the type of several columns in a single command\&.
+.PP
+If the command is written as
+ALTER FOREIGN TABLE IF EXISTS \&.\&.\&.
+and the foreign table does not exist, no error is thrown\&. A notice is issued in this case\&.
+.PP
+You must own the table to use
+\fBALTER FOREIGN TABLE\fR\&. To change the schema of a foreign table, you must also have
+CREATE
+privilege on the new schema\&. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have
+CREATE
+privilege on the table\*(Aqs schema\&. (These restrictions enforce that altering the owner doesn\*(Aqt do anything you couldn\*(Aqt do by dropping and recreating the table\&. However, a superuser can alter ownership of any table anyway\&.) To add a column or alter a column type, you must also have
+USAGE
+privilege on the data type\&.
+.SH "PARAMETERS"

+.PP
+You must own the function to use
+\fBALTER FUNCTION\fR\&. To change a function\*(Aqs schema, you must also have
+CREATE
+privilege on the new schema\&. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have

+.PP
+\fBALTER OPERATOR FAMILY\fR
+changes the definition of an operator family\&. You can add operators and support functions to the family, remove them from the family, or change the family\*(Aqs name or owner\&.
+.PP
+When operators and support functions are added to a family with
+\fBALTER OPERATOR FAMILY\fR, they are not part of any specific operator class within the family, but are just
+\(lqloose\(rq
+within the family\&. This indicates that these operators and functions are compatible with the family\*(Aqs semantics, but are not required for correct functioning of any specific index\&. (Operators and functions that are so required should be declared as part of an operator class, instead; see
+CREATE OPERATOR CLASS (\fBCREATE_OPERATOR_CLASS\fR(7))\&.)
+PostgreSQL
+will allow loose members of a family to be dropped from the family at any time, but members of an operator class cannot be dropped without dropping the whole class and any indexes that depend on it\&. Typically, single\-data\-type operators and functions are part of operator classes because they are needed to support an index on that specific data type, while cross\-data\-type operators and functions are made loose members of the family\&.
+.PP
+You must be a superuser to use
+\fBALTER OPERATOR FAMILY\fR\&. (This restriction is made because an erroneous operator family definition could confuse or even crash the server\&.)
+.PP
+\fBALTER OPERATOR FAMILY\fR
+does not presently check whether the operator family definition includes all the operators and functions required by the index method, nor whether the operators and functions form a self\-consistent set\&. It is the user\*(Aqs responsibility to define a valid operator family\&.

+.PP
+The

+.SH "NOTES"
+.PP
+Notice that the
+DROP
+syntax only specifies the
+\(lqslot\(rq
+in the operator family, by strategy or support number and input data type(s)\&. The name of the operator or function occupying the slot is not mentioned\&. Also, for
+DROP FUNCTION
+the type(s) to specify are the input data type(s) the function is intended to support; for GiST, SP\-GiST and GIN indexes this might have nothing to do with the actual input argument types of the function\&.
+.PP
+Because the index machinery does not check access permissions on functions before using them, including a function or operator in an operator family is tantamount to granting public execute permission on it\&. This is usually not an issue for the sorts of functions that are useful in an operator family\&.
+.PP
+The operators should not be defined by SQL functions\&. An SQL function is likely to be inlined into the calling query, which will prevent the optimizer from recognizing that the query matches an index\&.
+.PP
+Before
+PostgreSQL
+8\&.4, the
+OPERATOR
+clause could include a
+RECHECK
+option\&. This is no longer supported because whether an index operator is
+\(lqlossy\(rq
+is now determined on\-the\-fly at run time\&. This allows efficient handling of cases where an operator might or might not be lossy\&.

+The second variant changes the name of the role\&. Database superusers can rename any role\&. Roles having
+CREATEROLE

+\fBSET ROLE\fR

+Superusers can change anyone\*(Aqs session defaults\&. Roles having
+CREATEROLE

+.SH "DESCRIPTION"
+.PP
+\fBALTER TABLE\fR
+changes the definition of an existing table\&. There are several subforms described below\&. Note that the lock level required may differ for each subform\&. An
+ACCESS EXCLUSIVE
+lock is acquired unless explicitly noted\&. When multiple subcommands are given, the lock acquired will be the strictest one required by any subcommand\&.
+.PP
+ADD COLUMN [ IF NOT EXISTS ]
+.RS 4
+This form adds a new column to the table, using the same syntax as
+\fBCREATE TABLE\fR\&. If
+IF NOT EXISTS
+is specified and a column already exists with this name, no error is thrown\&.
+.RE
+.PP
+DROP COLUMN [ IF EXISTS ]
+.RS 4
+This form drops a column from a table\&. Indexes and table constraints involving the column will be automatically dropped as well\&. Multivariate statistics referencing the dropped column will also be removed if the removal of the column would cause the statistics to contain data for only a single column\&. You will need to say
+CASCADE
+if anything outside the table depends on the column, for example, foreign key references or views\&. If
+IF EXISTS
+is specified and the column does not exist, no error is thrown\&. In this case a notice is issued instead\&.
+.RE
+.PP
+SET DATA TYPE
+.RS 4
+This form changes the type of a column of a table\&. Indexes and simple table constraints involving the column will be automatically converted to use the new column type by reparsing the originally supplied expression\&. The optional
+COLLATE
+clause specifies a collation for the new column; if omitted, the collation is the default for the new column type\&. The optional
+USING
+clause specifies how to compute the new column value from the old; if omitted, the default conversion is the same as an assignment cast from old data type to new\&. A
+USING
+clause must be provided if there is no implicit or assignment cast from old to new type\&.
+.sp
+When this form is used, the column\*(Aqs statistics are removed, so running
+\fBANALYZE\fR
+on the table afterwards is recommended\&.
+.RE
+.PP
+SET/DROP DEFAULT
+.RS 4
+These forms set or remove the default value for a column (where removal is equivalent to setting the default value to NULL)\&. The new default value will only apply in subsequent
+\fBINSERT\fR
+or
+\fBUPDATE\fR
+commands; it does not cause rows already in the table to change\&.
+.RE
+.PP
+SET/DROP NOT NULL
+.RS 4
+These forms change whether a column is marked to allow null values or to reject null values\&.
+.sp
+SET NOT NULL
+may only be applied to a column provided none of the records in the table contain a
+NULL
+value for the column\&. Ordinarily this is checked during the
+ALTER TABLE
+by scanning the entire table; however, if a valid
+CHECK
+constraint is found which proves no
+NULL
+can exist, then the table scan is skipped\&.
+.sp
+If this table is a partition, one cannot perform
+DROP NOT NULL
+on a column if it is marked
+NOT NULL
+in the parent table\&. To drop the
+NOT NULL
+constraint from all the partitions, perform
+DROP NOT NULL
+on the parent table\&. Even if there is no
+NOT NULL
+constraint on the parent, such a constraint can still be added to individual partitions, if desired; that is, the children can disallow nulls even if the parent allows them, but not the other way around\&.
+.RE
+.PP
+DROP EXPRESSION [ IF EXISTS ]
+.RS 4
+This form turns a stored generated column into a normal base column\&. Existing data in the columns is retained, but future changes will no longer apply the generation expression\&.
+.sp
+If
+DROP EXPRESSION IF EXISTS
+is specified and the column is not a stored generated column, no error is thrown\&. In this case a notice is issued instead\&.
+.RE
+.PP
+ADD GENERATED { ALWAYS | BY DEFAULT } AS IDENTITY
+.br
+SET GENERATED { ALWAYS | BY DEFAULT }
+.br
+DROP IDENTITY [ IF EXISTS ]
+.RS 4
+These forms change whether a column is an identity column or change the generation attribute of an existing identity column\&. See
+\fBCREATE TABLE\fR
+for details\&. Like
+SET DEFAULT, these forms only affect the behavior of subsequent
+\fBINSERT\fR
+and
+\fBUPDATE\fR
+commands; they do not cause rows already in the table to change\&.
+.sp
+If
+DROP IDENTITY IF EXISTS
+is specified and the column is not an identity column, no error is thrown\&. In this case a notice is issued instead\&.
+.RE
+.PP
+SET \fIsequence_option\fR
+.br
+RESTART
+.RS 4
+These forms alter the sequence that underlies an existing identity column\&.
+\fIsequence_option\fR
+is an option supported by
+\fBALTER SEQUENCE\fR
+such as
+INCREMENT BY\&.
+.RE
+.PP
+SET STATISTICS
+.RS 4
+This form sets the per\-column statistics\-gathering target for subsequent
+\fBANALYZE\fR
+operations\&. The target can be set in the range 0 to 10000; alternatively, set it to \-1 to revert to using the system default statistics target (default_statistics_target)\&. For more information on the use of statistics by the
+PostgreSQL
+query planner, refer to
+Section\ \&14.2\&.
+.sp
+SET STATISTICS
+acquires a
+SHARE UPDATE EXCLUSIVE
+lock\&.
+.RE
+.PP
+SET ( \fIattribute_option\fR = \fIvalue\fR [, \&.\&.\&. ] )
+.br
+RESET ( \fIattribute_option\fR [, \&.\&.\&. ] )
+.RS 4
+This form sets or resets per\-attribute options\&. Currently, the only defined per\-attribute options are
+n_distinct
+and
+n_distinct_inherited, which override the number\-of\-distinct\-values estimates made by subsequent
+\fBANALYZE\fR
+operations\&.
+n_distinct
+affects the statistics for the table itself, while
+n_distinct_inherited
+affects the statistics gathered for the table plus its inheritance children\&. When set to a positive value,
+\fBANALYZE\fR
+will assume that the column contains exactly the specified number of distinct nonnull values\&. When set to a negative value, which must be greater than or equal to \-1,
+\fBANALYZE\fR
+will assume that the number of distinct nonnull values in the column is linear in the size of the table; the exact count is to be computed by multiplying the estimated table size by the absolute value of the given number\&. For example, a value of \-1 implies that all values in the column are distinct, while a value of \-0\&.5 implies that each value appears twice on the average\&. This can be useful when the size of the table changes over time, since the multiplication by the number of rows in the table is not performed until query planning time\&. Specify a value of 0 to revert to estimating the number of distinct values normally\&. For more information on the use of statistics by the
+PostgreSQL
+query planner, refer to
+Section\ \&14.2\&.
+.sp
+Changing per\-attribute options acquires a
+SHARE UPDATE EXCLUSIVE
+lock\&.
+.RE
+.PP
+SET STORAGE
+.RS 4
+This form sets the storage mode for a column\&. This controls whether this column is held inline or in a secondary
+TOAST
+table, and whether the data should be compressed or not\&.
+PLAIN
+must be used for fixed\-length values such as
+integer
+and is inline, uncompressed\&.
+MAIN
+is for inline, compressible data\&.
+EXTERNAL
+is for external, uncompressed data, and
+EXTENDED
+is for external, compressed data\&.
+EXTENDED
+is the default for most data types that support non\-PLAIN
+storage\&. Use of
+EXTERNAL
+will make substring operations on very large
+text
+and
+bytea
+values run faster, at the penalty of increased storage space\&. Note that
+SET STORAGE
+doesn\*(Aqt itself change anything in the table, it just sets the strategy to be pursued during future table updates\&. See
+Section\ \&73.2
+for more information\&.
+.RE
+.PP
+SET COMPRESSION \fIcompression_method\fR
+.RS 4
+This form sets the compression method for a column, determining how values inserted in future will be compressed (if the storage mode permits compression at all)\&. This does not cause the table to be rewritten, so existing data may still be compressed with other compression methods\&. If the table is restored with
+pg_restore, then all values are rewritten with the configured compression method\&. However, when data is inserted from another relation (for example, by
+\fBINSERT \&.\&.\&. SELECT\fR), values from the source table are not necessarily detoasted, so any previously compressed data may retain its existing compression method, rather than being recompressed with the compression method of the target column\&. The supported compression methods are
+pglz
+and
+lz4\&. (lz4
+is available only if
+\fB\-\-with\-lz4\fR
+was used when building
+PostgreSQL\&.) In addition,
+\fIcompression_method\fR
+can be
+default, which selects the default behavior of consulting the
+default_toast_compression
+setting at the time of data insertion to determine the method to use\&.
+.RE
+.PP
+ADD \fItable_constraint\fR [ NOT VALID ]
+.RS 4
+This form adds a new constraint to a table using the same constraint syntax as
+\fBCREATE TABLE\fR, plus the option
+NOT VALID, which is currently only allowed for foreign key and CHECK constraints\&.
+.sp
+Normally, this form will cause a scan of the table to verify that all existing rows in the table satisfy the new constraint\&. But if the
+NOT VALID
+option is used, this potentially\-lengthy scan is skipped\&. The constraint will still be enforced against subsequent inserts or updates (that is, they\*(Aqll fail unless there is a matching row in the referenced table, in the case of foreign keys, or they\*(Aqll fail unless the new row matches the specified check condition)\&. But the database will not assume that the constraint holds for all rows in the table, until it is validated by using the
+VALIDATE CONSTRAINT
+option\&. See
+Notes
+below for more information about using the
+NOT VALID
+option\&.
+.sp
+Although most forms of
+ADD \fItable_constraint\fR
+require an
+ACCESS EXCLUSIVE
+lock,
+ADD FOREIGN KEY
+requires only a
+SHARE ROW EXCLUSIVE
+lock\&. Note that
+ADD FOREIGN KEY
+also acquires a
+SHARE ROW EXCLUSIVE
+lock on the referenced table, in addition to the lock on the table on which the constraint is declared\&.
+.sp
+Additional restrictions apply when unique or primary key constraints are added to partitioned tables; see
+\fBCREATE TABLE\fR\&. Also, foreign key constraints on partitioned tables may not be declared
+NOT VALID
+at present\&.
+.RE
+.PP
+ADD \fItable_constraint_using_index\fR
+.RS 4
+This form adds a new
+PRIMARY KEY
+or
+UNIQUE
+constraint to a table based on an existing unique index\&. All the columns of the index will be included in the constraint\&.
+.sp
+The index cannot have expression columns nor be a partial index\&. Also, it must be a b\-tree index with default sort ordering\&. These restrictions ensure that the index is equivalent to one that would be built by a regular
+ADD PRIMARY KEY
+or
+ADD UNIQUE
+command\&.
+.sp
+If
+PRIMARY KEY
+is specified, and the index\*(Aqs columns are not already marked
+NOT NULL, then this command will attempt to do
+ALTER COLUMN SET NOT NULL
+against each such column\&. That requires a full table scan to verify the column(s) contain no nulls\&. In all other cases, this is a fast operation\&.
+.sp
+If a constraint name is provided then the index will be renamed to match the constraint name\&. Otherwise the constraint will be named the same as the index\&.
+.sp
+After this command is executed, the index is
+\(lqowned\(rq
+by the constraint, in the same way as if the index had been built by a regular
+ADD PRIMARY KEY
+or
+ADD UNIQUE
+command\&. In particular, dropping the constraint will make the index disappear too\&.

+DROP CONSTRAINT [ IF EXISTS ]

+.RE
+.PP
+DISABLE/ENABLE [ REPLICA | ALWAYS ] TRIGGER
+.RS 4
+These forms configure the firing of trigger(s) belonging to the table\&. A disabled trigger is still known to the system, but is not executed when its triggering event occurs\&. (For a deferred trigger, the enable status is checked when the event occurs, not when the trigger function is actually executed\&.) One can disable or enable a single trigger specified by name, or all triggers on the table, or only user triggers (this option excludes internally generated constraint triggers, such as those that are used to implement foreign key constraints or deferrable uniqueness and exclusion constraints)\&. Disabling or enabling internally generated constraint triggers requires superuser privileges; it should be done with caution since of course the integrity of the constraint cannot be guaranteed if the triggers are not executed\&.
+.sp
+The trigger firing mechanism is also affected by the configuration variable
+session_replication_role\&. Simply enabled triggers (the default) will fire when the replication role is
+\(lqorigin\(rq
+(the default) or
+\(lqlocal\(rq\&. Triggers configured as
+ENABLE REPLICA
+will only fire if the session is in
+\(lqreplica\(rq
+mode, and triggers configured as
+ENABLE ALWAYS
+will fire regardless of the current replication role\&.
+.sp
+The effect of this mechanism is that in the default configuration, triggers do not fire on replicas\&. This is useful because if a trigger is used on the origin to propagate data between tables, then the replication system will also replicate the propagated data; so the trigger should not fire a second time on the replica, because that would lead to duplication\&. However, if a trigger is used for another purpose such as creating external alerts, then it might be appropriate to set it to
+ENABLE ALWAYS
+so that it is also fired on replicas\&.
+.sp
+When this command is applied to a partitioned table, the states of corresponding clone triggers in the partitions are updated too, unless
+ONLY
+is specified\&.

+This command acquires a
+SHARE ROW EXCLUSIVE
+lock\&.
+.RE
+.PP
+DISABLE/ENABLE [ REPLICA | ALWAYS ] RULE

+ON SELECT
+rules, which are always applied in order to keep views working even if the current session is in a non\-default replication role\&.

+DISABLE/ENABLE ROW LEVEL SECURITY

+ATTACH PARTITION \fIpartition_name\fR { FOR VALUES \fIpartition_bound_spec\fR | DEFAULT }
+.RS 4
+This form attaches an existing table (which might itself be partitioned) as a partition of the target table\&. The table can be attached as a partition for specific values using
+FOR VALUES
+or as a default partition by using
+DEFAULT\&. For each index in the target table, a corresponding one will be created in the attached table; or, if an equivalent index already exists, it will be attached to the target table\*(Aqs index, as if
+\fBALTER INDEX ATTACH PARTITION\fR
+had been executed\&. Note that if the existing table is a foreign table, it is currently not allowed to attach the table as a partition of the target table if there are
+UNIQUE
+indexes on the target table\&. (See also

+.sp
+A partition using

+uses same syntax for

The table to be attached must have all the same columns as the target table and no more; moreover, the column types must also match\&. Also, it must have all the

+constraints of the target table\&. Currently
+FOREIGN KEY
+constraints are not considered\&.
+UNIQUE

+PRIMARY KEY
+constraints from the parent table will be created in the partition, if they don\*(Aqt already exist\&. If any of the
+CHECK
+constraints of the table being attached are marked
+NO INHERIT, the command will fail; such constraints must be recreated without the
+NO INHERIT
+clause\&.
+.sp
+If the new partition is a regular table, a full table scan is performed to check that existing rows in the table do not violate the partition constraint\&. It is possible to avoid this scan by adding a valid
+CHECK
+constraint to the table that allows only rows satisfying the desired partition constraint before running this command\&. The
+CHECK
+constraint will be used to determine that the table need not be scanned to validate the partition constraint\&. This does not work, however, if any of the partition keys is an expression and the partition does not accept
+NULL
+values\&. If attaching a list partition that will not accept
+NULL
+values, also add a
+NOT NULL
+constraint to the partition key column, unless it\*(Aqs an expression\&.
+.sp
+If the new partition is a foreign table, nothing is done to verify that all the rows in the foreign table obey the partition constraint\&. (See the discussion in
+CREATE FOREIGN TABLE (\fBCREATE_FOREIGN_TABLE\fR(7))
+about constraints on the foreign table\&.)
+.sp
+When a table has a default partition, defining a new partition changes the partition constraint for the default partition\&. The default partition can\*(Aqt contain any rows that would need to be moved to the new partition, and will be scanned to verify that none are present\&. This scan, like the scan of the new partition, can be avoided if an appropriate
+CHECK
+constraint is present\&. Also like the scan of the new partition, it is always skipped when the default partition is a foreign table\&.
+.sp
+Attaching a partition acquires a
+SHARE UPDATE EXCLUSIVE
+lock on the parent table, in addition to the
+ACCESS EXCLUSIVE
+locks on the table being attached and on the default partition (if any)\&.
+.sp
+Further locks must also be held on all sub\-partitions if the table being attached is itself a partitioned table\&. Likewise if the default partition is itself a partitioned table\&. The locking of the sub\-partitions can be avoided by adding a

Any indexes that were attached to the target table\*(Aqs indexes are detached\&. Any triggers that were created as clones of those in the target table are removed\&.
+SHARE
+lock is obtained on any tables that reference this partitioned table in foreign key constraints\&.
+.sp
+If
+CONCURRENTLY
+is specified, it runs using a reduced lock level to avoid blocking other sessions that might be accessing the partitioned table\&. In this mode, two transactions are used internally\&. During the first transaction, a
+SHARE UPDATE EXCLUSIVE
+lock is taken on both parent table and partition, and the partition is marked as undergoing detach; at that point, the transaction is committed and all other transactions using the partitioned table are waited for\&. Once all those transactions have completed, the second transaction acquires
+SHARE UPDATE EXCLUSIVE
+on the partitioned table and
+ACCESS EXCLUSIVE
+on the partition, and the detach process completes\&. A
+CHECK
+constraint that duplicates the partition constraint is added to the partition\&.
+CONCURRENTLY
+cannot be run in a transaction block and is not allowed if the partitioned table contains a default partition\&.

+When a column is added with
+ADD COLUMN
+and a non\-volatile
+DEFAULT
+is specified, the default is evaluated at the time of the statement and the result stored in the table\*(Aqs metadata\&. That value will be used for the column for all existing rows\&. If no
+DEFAULT
+is specified, NULL is used\&. In neither case is a rewrite of the table required\&.
+.PP
+Adding a column with a volatile
+DEFAULT
+or changing the type of an existing column will require the entire table and its indexes to be rewritten\&. As an exception, when changing the type of an existing column, if the
+USING
+clause does not change the column contents and the old type is either binary coercible to the new type or an unconstrained domain over the new type, a table rewrite is not needed\&. However, indexes must always be rebuilt unless the system can verify that the new index would be logically equivalent to the existing one\&. For example, if the collation for a column has been changed, an index rebuild is always required because the new sort order might be different\&. However, in the absence of a collation change, a column can be changed from
+text
+to
+varchar
+(or vice versa) without rebuilding the indexes because these data types sort identically\&. Table and/or index rebuilds may take a significant amount of time for a large table; and will temporarily require as much as double the disk space\&.
+.PP
+Adding a
+CHECK
+or
+NOT NULL
+constraint requires scanning the table to verify that existing rows meet the constraint, but does not require a table rewrite\&.
+.PP
+Similarly, when attaching a new partition it may be scanned to verify that existing rows meet the partition constraint\&.
+.PP
+The main reason for providing the option to specify multiple changes in a single
+\fBALTER TABLE\fR
+is that multiple table scans or rewrites can thereby be combined into a single pass over the table\&.
+.PP
+Scanning a large table to verify a new foreign key or check constraint can take a long time, and other updates to the table are locked out until the
+\fBALTER TABLE ADD CONSTRAINT\fR
+command is committed\&. The main purpose of the
+NOT VALID
+constraint option is to reduce the impact of adding a constraint on concurrent updates\&. With
+NOT VALID, the
+\fBADD CONSTRAINT\fR
+command does not scan the table and can be committed immediately\&. After that, a
+VALIDATE CONSTRAINT
+command can be issued to verify that existing rows satisfy the constraint\&. The validation step does not need to lock out concurrent updates, since it knows that other transactions will be enforcing the constraint for rows that they insert or update; only pre\-existing rows need to be checked\&. Hence, validation acquires only a
+SHARE UPDATE EXCLUSIVE
+lock on the table being altered\&. (If the constraint is a foreign key then a
+ROW SHARE
+lock is also required on the table referenced by the constraint\&.) In addition to improving concurrency, it can be useful to use
+NOT VALID
+and
+VALIDATE CONSTRAINT
+in cases where the table is known to contain pre\-existing violations\&. Once the constraint is in place, no new violations can be inserted, and the existing problems can be corrected at leisure until
+VALIDATE CONSTRAINT
+finally succeeds\&.
+.PP
+The
+DROP COLUMN
+form does not physically remove the column, but simply makes it invisible to SQL operations\&. Subsequent insert and update operations in the table will store a null value for the column\&. Thus, dropping a column is quick but it will not immediately reduce the on\-disk size of your table, as the space occupied by the dropped column is not reclaimed\&. The space will be reclaimed over time as existing rows are updated\&.
+.PP
+To force immediate reclamation of space occupied by a dropped column, you can execute one of the forms of
+\fBALTER TABLE\fR
+that performs a rewrite of the whole table\&. This results in reconstructing each row with the dropped column replaced by a null value\&.
+.PP
+The rewriting forms of
+\fBALTER TABLE\fR
+are not MVCC\-safe\&. After a table rewrite, the table will appear empty to concurrent transactions, if they are using a snapshot taken before the rewrite occurred\&. See
+Section\ \&13.6
+for more details\&.
+.PP
+The
+USING
+option of
+SET DATA TYPE
+can actually specify any expression involving the old values of the row; that is, it can refer to other columns as well as the one being converted\&. This allows very general conversions to be done with the
+SET DATA TYPE
+syntax\&. Because of this flexibility, the
+USING
+expression is not applied to the column\*(Aqs default value (if any); the result might not be a constant expression as required for a default\&. This means that when there is no implicit or assignment cast from old to new type,
+SET DATA TYPE
+might fail to convert the default even though a
+USING
+clause is supplied\&. In such cases, drop the default with
+DROP DEFAULT, perform the
+ALTER TYPE, and then use
+SET DEFAULT
+to add a suitable new default\&. Similar considerations apply to indexes and constraints involving the column\&.
+.PP
+If a table has any descendant tables, it is not permitted to add, rename, or change the type of a column in the parent table without doing the same to the descendants\&. This ensures that the descendants always have columns matching the parent\&. Similarly, a
+CHECK
+constraint cannot be renamed in the parent without also renaming it in all descendants, so that
+CHECK
+constraints also match between the parent and its descendants\&. (That restriction does not apply to index\-based constraints, however\&.) Also, because selecting from the parent also selects from its descendants, a constraint on the parent cannot be marked valid unless it is also marked valid for those descendants\&. In all of these cases,
+\fBALTER TABLE ONLY\fR
+will be rejected\&.
+.PP
+A recursive
+DROP COLUMN
+operation will remove a descendant table\*(Aqs column only if the descendant does not inherit that column from any other parents and never had an independent definition of the column\&. A nonrecursive
+DROP COLUMN
+(i\&.e\&.,
+\fBALTER TABLE ONLY \&.\&.\&. DROP COLUMN\fR) never removes any descendant columns, but instead marks them as independently defined rather than inherited\&. A nonrecursive
+DROP COLUMN
+command will fail for a partitioned table, because all partitions of a table must have the same columns as the partitioning root\&.
+.PP
+The actions for identity columns (ADD GENERATED,
+SET
+etc\&.,
+DROP IDENTITY), as well as the actions
+CLUSTER,
+OWNER, and
+TABLESPACE
+never recurse to descendant tables; that is, they always act as though
+ONLY
+were specified\&. Actions affecting trigger states recurse to partitions of partitioned tables (unless
+ONLY
+is specified), but never to traditional\-inheritance descendants\&. Adding a constraint recurses only for

+\fBALTER TYPE\fR
+changes the definition of an existing type\&. There are several subforms:
+.PP
+OWNER
+.RS 4
+This form changes the owner of the type\&.
+.RE
+.PP
+RENAME
+.RS 4
+This form changes the name of the type\&.
+.RE
+.PP
+SET SCHEMA
+.RS 4
+This form moves the type into another schema\&.
+.RE
+.PP
+RENAME ATTRIBUTE
+.RS 4
+This form is only usable with composite types\&. It changes the name of an individual attribute of the type\&.
+.RE
+.PP
+ADD ATTRIBUTE
+.RS 4
+This form adds a new attribute to a composite type, using the same syntax as
+\fBCREATE TYPE\fR\&.
+.RE
+.PP
+DROP ATTRIBUTE [ IF EXISTS ]
+.RS 4
+This form drops an attribute from a composite type\&. If

+.RE
+.PP
+ALTER ATTRIBUTE \&.\&.\&. SET DATA TYPE
+.RS 4
+This form changes the type of an attribute of a composite type\&.
+.RE
+.PP
+ADD VALUE [ IF NOT EXISTS ] [ BEFORE | AFTER ]
+.RS 4
+This form adds a new value to an enum type\&. The new value\*(Aqs place in the enum\*(Aqs ordering can be specified as being
+BEFORE
+or
+AFTER
+one of the existing values\&. Otherwise, the new item is added at the end of the list of values\&.
+.sp
+If
+IF NOT EXISTS
+is specified, it is not an error if the type already contains the new value: a notice is issued but no other action is taken\&. Otherwise, an error will occur if the new value is already present\&.
+.RE
+.PP
+RENAME VALUE
+.RS 4
+This form renames a value of an enum type\&. The value\*(Aqs place in the enum\*(Aqs ordering is not affected\&. An error will occur if the specified value is not present or the new name is already present\&.
+.RE
+.PP
+SET ( \fIproperty\fR = \fIvalue\fR [, \&.\&.\&. ] )
+.RS 4
+This form is only applicable to base types\&. It allows adjustment of a subset of the base\-type properties that can be set in
+\fBCREATE TYPE\fR\&. Specifically, these properties can be changed:

+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c

+can be set to
+plain,
+extended,
+external, or

+(see
+Section\ \&73.2
+for more information about what these mean)\&. However, changing from
+plain
+to another setting requires superuser privilege (because it requires that the type\*(Aqs C functions all be TOAST\-ready), and changing to
+plain
+from another setting is not allowed at all (since the type may already have TOASTed values present in the database)\&. Note that changing this option doesn\*(Aqt by itself change any stored data, it just sets the default TOAST strategy to be used for table columns created in the future\&. See
+ALTER TABLE (\fBALTER_TABLE\fR(7))
+to change the TOAST strategy for existing table columns\&.
+.RE
+.sp
+See
+CREATE TYPE (\fBCREATE_TYPE\fR(7))
+for more details about these type properties\&. Note that where appropriate, a change in these properties for a base type will be propagated automatically to domains based on that type\&.
+.RE
+.PP
+The
+ADD ATTRIBUTE,
+DROP ATTRIBUTE, and
+ALTER ATTRIBUTE
+actions can be combined into a list of multiple alterations to apply in parallel\&. For example, it is possible to add several attributes and/or alter the type of several attributes in a single command\&.
+.PP
+You must own the type to use
+\fBALTER TYPE\fR\&. To change the schema of a type, you must also have
+CREATE
+privilege on the new schema\&. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have
+CREATE
+privilege on the type\*(Aqs schema\&. (These restrictions enforce that altering the owner doesn\*(Aqt do anything you couldn\*(Aqt do by dropping and recreating the type\&. However, a superuser can alter ownership of any type anyway\&.) To add an attribute or alter an attribute type, you must also have
+USAGE
+privilege on the attribute\*(Aqs data type\&.

+.SH "NOTES"
+.PP
+If
+\fBALTER TYPE \&.\&.\&. ADD VALUE\fR
+(the form that adds a new value to an enum type) is executed inside a transaction block, the new value cannot be used until after the transaction has been committed\&.
+.PP
+Comparisons involving an added enum value will sometimes be slower than comparisons involving only original members of the enum type\&. This will usually only occur if
+BEFORE
+or

+is used to set the new value\*(Aqs sort position somewhere other than at the end of the list\&. However, sometimes it will happen even though the new value is added at the end (this occurs if the OID counter
+\(lqwrapped around\(rq
+since the original creation of the enum type)\&. The slowdown is usually insignificant; but if it matters, optimal performance can be regained by dropping and recreating the enum type, or by dumping and restoring the database\&.

+.fi
+.SH "DESCRIPTION"
+.PP
+\fBANALYZE\fR
+collects statistics about the contents of tables in the database, and stores the results in the
+pg_statistic
+system catalog\&. Subsequently, the query planner uses these statistics to help determine the most efficient execution plans for queries\&.
+.PP
+Without a
+\fItable_and_columns\fR
+list,
+\fBANALYZE\fR
+processes every table and materialized view in the current database that the current user has permission to analyze\&. With a list,
+\fBANALYZE\fR
+processes only those table(s)\&. It is further possible to give a list of column names for a table, in which case only the statistics for those columns are collected\&.
+.PP
+When the option list is surrounded by parentheses, the options can be written in any order\&. The parenthesized syntax was added in
+PostgreSQL
+11; the unparenthesized syntax is deprecated\&.
+.SH "PARAMETERS"
+.PP
+VERBOSE
+.RS 4
+Enables display of progress messages\&.
+.RE
+.PP
+SKIP_LOCKED
+.RS 4
+Specifies that
+\fBANALYZE\fR
+should not wait for any conflicting locks to be released when beginning work on a relation: if a relation cannot be locked immediately without waiting, the relation is skipped\&. Note that even with this option,
+\fBANALYZE\fR
+may still block when opening the relation\*(Aqs indexes or when acquiring sample rows from partitions, table inheritance children, and some types of foreign tables\&. Also, while
+\fBANALYZE\fR
+ordinarily processes all partitions of specified partitioned tables, this option will cause
+\fBANALYZE\fR
+to skip all partitions if there is a conflicting lock on the partitioned table\&.
+.RE
+.PP
+\fIboolean\fR
+.RS 4
+Specifies whether the selected option should be turned on or off\&. You can write
+TRUE,
+ON, or
+1
+to enable the option, and
+FALSE,
+OFF, or
+0
+to disable it\&. The
+\fIboolean\fR
+value can also be omitted, in which case
+TRUE
+is assumed\&.
+.RE
+.PP
+\fItable_name\fR
+.RS 4
+The name (possibly schema\-qualified) of a specific table to analyze\&. If omitted, all regular tables, partitioned tables, and materialized views in the current database are analyzed (but not foreign tables)\&. If the specified table is a partitioned table, both the inheritance statistics of the partitioned table as a whole and statistics of the individual partitions are updated\&.
+.RE
+.PP
+\fIcolumn_name\fR
+.RS 4
+The name of a specific column to analyze\&. Defaults to all columns\&.
+.RE
+.SH "OUTPUTS"
+.PP
+When
+VERBOSE
+is specified,
+\fBANALYZE\fR
+emits progress messages to indicate which table is currently being processed\&. Various statistics about the tables are printed as well\&.
+.SH "NOTES"
+.PP
+To analyze a table, one must ordinarily be the table\*(Aqs owner or a superuser\&. However, database owners are allowed to analyze all tables in their databases, except shared catalogs\&. (The restriction for shared catalogs means that a true database\-wide
+\fBANALYZE\fR
+can only be performed by a superuser\&.)
+\fBANALYZE\fR
+will skip over any tables that the calling user does not have permission to analyze\&.
+.PP
+Foreign tables are analyzed only when explicitly selected\&. Not all foreign data wrappers support
+\fBANALYZE\fR\&. If the table\*(Aqs wrapper does not support
+\fBANALYZE\fR, the command prints a warning and does nothing\&.
+.PP
+In the default
+PostgreSQL
+configuration, the autovacuum daemon (see
+Section\ \&25.1.6) takes care of automatic analyzing of tables when they are first loaded with data, and as they change throughout regular operation\&. When autovacuum is disabled, it is a good idea to run
+\fBANALYZE\fR
+periodically, or just after making major changes in the contents of a table\&. Accurate statistics will help the planner to choose the most appropriate query plan, and thereby improve the speed of query processing\&. A common strategy for read\-mostly databases is to run
+\fBVACUUM\fR
+and
+\fBANALYZE\fR
+once a day during a low\-usage time of day\&. (This will not be sufficient if there is heavy update activity\&.)
+.PP
+\fBANALYZE\fR
+requires only a read lock on the target table, so it can run in parallel with other activity on the table\&.
+.PP
+The statistics collected by
+\fBANALYZE\fR
+usually include a list of some of the most common values in each column and a histogram showing the approximate data distribution in each column\&. One or both of these can be omitted if
+\fBANALYZE\fR
+deems them uninteresting (for example, in a unique\-key column, there are no common values) or if the column data type does not support the appropriate operators\&. There is more information about the statistics in
+Chapter\ \&25\&.
+.PP
+For large tables,
+\fBANALYZE\fR
+takes a random sample of the table contents, rather than examining every row\&. This allows even very large tables to be analyzed in a small amount of time\&. Note, however, that the statistics are only approximate, and will change slightly each time
+\fBANALYZE\fR
+is run, even if the actual table contents did not change\&. This might result in small changes in the planner\*(Aqs estimated costs shown by
+\fBEXPLAIN\fR\&. In rare situations, this non\-determinism will cause the planner\*(Aqs choices of query plans to change after
+\fBANALYZE\fR
+is run\&. To avoid this, raise the amount of statistics collected by
+\fBANALYZE\fR, as described below\&.
+.PP
+The extent of analysis can be controlled by adjusting the
+default_statistics_target
+configuration variable, or on a column\-by\-column basis by setting the per\-column statistics target with
+\fBALTER TABLE \&.\&.\&. ALTER COLUMN \&.\&.\&. SET STATISTICS\fR\&. The target value sets the maximum number of entries in the most\-common\-value list and the maximum number of bins in the histogram\&. The default target value is 100, but this can be adjusted up or down to trade off accuracy of planner estimates against the time taken for
+\fBANALYZE\fR
+and the amount of space occupied in
+pg_statistic\&. In particular, setting the statistics target to zero disables collection of statistics for that column\&. It might be useful to do that for columns that are never used as part of the
+WHERE,
+GROUP BY, or
+ORDER BY
+clauses of queries, since the planner will have no use for statistics on such columns\&.
+.PP
+The largest statistics target among the columns being analyzed determines the number of table rows sampled to prepare the statistics\&. Increasing the target causes a proportional increase in the time and space needed to do
+\fBANALYZE\fR\&.
+.PP
+One of the values estimated by
+\fBANALYZE\fR
+is the number of distinct values that appear in each column\&. Because only a subset of the rows are examined, this estimate can sometimes be quite inaccurate, even with the largest possible statistics target\&. If this inaccuracy leads to bad query plans, a more accurate value can be determined manually and then installed with
+\fBALTER TABLE \&.\&.\&. ALTER COLUMN \&.\&.\&. SET (n_distinct = \&.\&.\&.)\fR\&.
+.PP
+If the table being analyzed has inheritance children,
+\fBANALYZE\fR
+gathers two sets of statistics: one on the rows of the parent table only, and a second including rows of both the parent table and all of its children\&. This second set of statistics is needed when planning queries that process the inheritance tree as a whole\&. The child tables themselves are not individually analyzed in this case\&. The autovacuum daemon, however, will only consider inserts or updates on the parent table itself when deciding whether to trigger an automatic analyze for that table\&. If that table is rarely inserted into or updated, the inheritance statistics will not be up to date unless you run
+\fBANALYZE\fR
+manually\&.
+.PP
+For partitioned tables,
+\fBANALYZE\fR
+gathers statistics by sampling rows from all partitions; in addition, it will recurse into each partition and update its statistics\&. Each leaf partition is analyzed only once, even with multi\-level partitioning\&. No statistics are collected for only the parent table (without data from its partitions), because with partitioning it\*(Aqs guaranteed to be empty\&.
+.PP
+The autovacuum daemon does not process partitioned tables, nor does it process inheritance parents if only the children are ever modified\&. It is usually necessary to periodically run a manual
+\fBANALYZE\fR
+to keep the statistics of the table hierarchy up to date\&.
+.PP
+If any child tables or partitions are foreign tables whose foreign data wrappers do not support
+\fBANALYZE\fR, those tables are ignored while gathering inheritance statistics\&.
+.PP
+If the table being analyzed is completely empty,
+\fBANALYZE\fR
+will not record new statistics for that table\&. Any existing statistics will be retained\&.
+.PP
+Each backend running
+\fBANALYZE\fR
+will report its progress in the
+pg_stat_progress_analyze
+view\&. See
+Section\ \&28.4.1
+for details\&.
+.SH "COMPATIBILITY"

+statement in the SQL standard\&.

+.SH "DESCRIPTION"
+.PP
+\fBCLUSTER\fR
+instructs
+PostgreSQL
+to cluster the table specified by
+\fItable_name\fR
+based on the index specified by
+\fIindex_name\fR\&. The index must already have been defined on
+\fItable_name\fR\&.
+.PP
+When a table is clustered, it is physically reordered based on the index information\&. Clustering is a one\-time operation: when the table is subsequently updated, the changes are not clustered\&. That is, no attempt is made to store new or updated rows according to their index order\&. (If one wishes, one can periodically recluster by issuing the command again\&. Also, setting the table\*(Aqs
+fillfactor
+storage parameter to less than 100% can aid in preserving cluster ordering during updates, since updated rows are kept on the same page if enough space is available there\&.)
+.PP
+When a table is clustered,
+PostgreSQL
+remembers which index it was clustered by\&. The form
+\fBCLUSTER \fR\fB\fItable_name\fR\fR
+reclusters the table using the same index as before\&. You can also use the
+CLUSTER
+or
+SET WITHOUT CLUSTER
+forms of
+\fBALTER TABLE\fR
+to set the index to be used for future cluster operations, or to clear any previous setting\&.
+.PP
+\fBCLUSTER\fR
+without any parameter reclusters all the previously\-clustered tables in the current database that the calling user owns, or all such tables if called by a superuser\&. This form of
+\fBCLUSTER\fR
+cannot be executed inside a transaction block\&.
+.PP
+When a table is being clustered, an
+ACCESS EXCLUSIVE
+lock is acquired on it\&. This prevents any other database operations (both reads and writes) from operating on the table until the
+\fBCLUSTER\fR
+is finished\&.
+.SH "PARAMETERS"
+.PP
+\fItable_name\fR
+.RS 4
+The name (possibly schema\-qualified) of a table\&.
+.RE
+.PP
+\fIindex_name\fR
+.RS 4
+The name of an index\&.
+.RE
+.PP
+VERBOSE
+.RS 4
+Prints a progress report as each table is clustered\&.
+.RE
+.PP
+\fIboolean\fR
+.RS 4
+Specifies whether the selected option should be turned on or off\&. You can write
+TRUE,
+ON, or
+1
+to enable the option, and
+FALSE,
+OFF, or
+0
+to disable it\&. The
+\fIboolean\fR
+value can also be omitted, in which case
+TRUE
+is assumed\&.
+.RE
+.SH "NOTES"
+.PP
+In cases where you are accessing single rows randomly within a table, the actual order of the data in the table is unimportant\&. However, if you tend to access some data more than others, and there is an index that groups them together, you will benefit from using
+\fBCLUSTER\fR\&. If you are requesting a range of indexed values from a table, or a single indexed value that has multiple rows that match,
+\fBCLUSTER\fR
+will help because once the index identifies the table page for the first row that matches, all other rows that match are probably already on the same table page, and so you save disk accesses and speed up the query\&.
+.PP
+\fBCLUSTER\fR
+can re\-sort the table using either an index scan on the specified index, or (if the index is a b\-tree) a sequential scan followed by sorting\&. It will attempt to choose the method that will be faster, based on planner cost parameters and available statistical information\&.
+.PP
+When an index scan is used, a temporary copy of the table is created that contains the table data in the index order\&. Temporary copies of each index on the table are created as well\&. Therefore, you need free space on disk at least equal to the sum of the table size and the index sizes\&.
+.PP
+When a sequential scan and sort is used, a temporary sort file is also created, so that the peak temporary space requirement is as much as double the table size, plus the index sizes\&. This method is often faster than the index scan method, but if the disk space requirement is intolerable, you can disable this choice by temporarily setting
+enable_sort
+to
+off\&.
+.PP
+It is advisable to set
+maintenance_work_mem
+to a reasonably large value (but not more than the amount of RAM you can dedicate to the
+\fBCLUSTER\fR
+operation) before clustering\&.
+.PP
+Because the planner records statistics about the ordering of tables, it is advisable to run
+\fBANALYZE\fR
+on the newly clustered table\&. Otherwise, the planner might make poor choices of query plans\&.
+.PP
+Because
+\fBCLUSTER\fR
+remembers which indexes are clustered, one can cluster the tables one wants clustered manually the first time, then set up a periodic maintenance script that executes
+\fBCLUSTER\fR
+without any parameters, so that the desired tables are periodically reclustered\&.
+.PP
+Each backend running
+\fBCLUSTER\fR
+will report its progress in the
+pg_stat_progress_cluster
+view\&. See
+Section\ \&28.4.4
+for details\&.
+.PP
+Clustering a partitioned table clusters each of its partitions using the partition of the specified partitioned index\&. When clustering a partitioned table, the index may not be omitted\&.
+.SH "EXAMPLES"
+.PP
+Cluster the table
+employees
+on the basis of its index
+employees_ind:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CLUSTER employees USING employees_ind;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Cluster the
+employees
+table using the same index that was used before:
+.sp
+.if n \{\
+.RS 4

+.nf
+CLUSTER employees;
+.fi

+Cluster all tables in the database that have previously been clustered:
+.sp
+.if n \{\

+.SH "DESCRIPTION"
+.PP
+\fBCOMMENT\fR
+stores a comment about a database object\&.
+.PP
+Only one comment string is stored for each object, so to modify a comment, issue a new
+\fBCOMMENT\fR
+command for the same object\&. To remove a comment, write
+NULL
+in place of the text string\&. Comments are automatically dropped when their object is dropped\&.
+.PP
+A
+SHARE UPDATE EXCLUSIVE
+lock is acquired on the object to be commented\&.
+.PP
+For most kinds of object, only the object\*(Aqs owner can set the comment\&. Roles don\*(Aqt have owners, so the rule for
+COMMENT ON ROLE
+is that you must be superuser to comment on a superuser role, or have the
+CREATEROLE
+privilege to comment on non\-superuser roles\&. Likewise, access methods don\*(Aqt have owners either; you must be superuser to comment on an access method\&. Of course, a superuser can comment on anything\&.
+.PP
+Comments can be viewed using
+psql\*(Aqs
+\fB\ed\fR
+family of commands\&. Other user interfaces to retrieve comments can be built atop the same built\-in functions that
+psql
+uses, namely
+\fBobj_description\fR,
+\fBcol_description\fR, and
+\fBshobj_description\fR

+Table\ \&9.77)\&.

+\fIto\fR
+a file, while
+\fBCOPY FROM\fR
+copies data
+\fIfrom\fR
+a file to a table (appending the data to whatever is in the table already)\&.
+\fBCOPY TO\fR
+can also copy the results of a
+\fBSELECT\fR
+query\&.
+.PP
+If a column list is specified,
+\fBCOPY TO\fR
+copies only the data in the specified columns to the file\&. For
+\fBCOPY FROM\fR, each field in the file is inserted, in order, into the specified column\&. Table columns not specified in the
+\fBCOPY FROM\fR
+column list will receive their default values\&.
+.PP
+\fBCOPY\fR
+with a file name instructs the
+PostgreSQL
+server to directly read from or write to a file\&. The file must be accessible by the
+PostgreSQL
+user (the user ID the server runs as) and the name must be specified from the viewpoint of the server\&. When
+PROGRAM
+is specified, the server executes the given command and reads from the standard output of the program, or writes to the standard input of the program\&. The command must be specified from the viewpoint of the server, and be executable by the
+PostgreSQL
+user\&. When
+STDIN
+or
+STDOUT
+is specified, data is transmitted via the connection between the client and the server\&.

+.sp
+Note that the command is invoked by the shell, so if you need to pass any arguments to shell command that come from an untrusted source, you must be careful to strip or escape any special characters that might have a special meaning for the shell\&. For security reasons, it is best to use a fixed command string, or at least avoid passing any user input in it\&.

+\fBCOPY TO\fR

+COPY (SELECT * FROM \fItable\fR) TO \&.\&.\&.

+.PP
+\fBCOPY FROM\fR
+can be used with plain, foreign, or partitioned tables or with views that have
+INSTEAD OF INSERT
+triggers\&.
+.PP
+You must have select privilege on the table whose values are read by
+\fBCOPY TO\fR, and insert privilege on the table into which values are inserted by
+\fBCOPY FROM\fR\&. It is sufficient to have column privileges on the column(s) listed in the command\&.
+.PP
+If row\-level security is enabled for the table, the relevant
+\fBSELECT\fR
+policies will apply to
+COPY \fItable\fR TO
+statements\&. Currently,
+\fBCOPY FROM\fR
+is not supported for tables with row\-level security\&. Use equivalent
+\fBINSERT\fR
+statements instead\&.
+.PP
+Files named in a
+\fBCOPY\fR
+command are read or written directly by the server, not by the client application\&. Therefore, they must reside on or be accessible to the database server machine, not the client\&. They must be accessible to and readable or writable by the
+PostgreSQL
+user (the user ID the server runs as), not the client\&. Similarly, the command specified with
+PROGRAM
+is executed directly by the server, not by the client application, must be executable by the
+PostgreSQL
+user\&.
+\fBCOPY\fR
+naming a file or command is only allowed to database superusers or users who are granted one of the roles
+pg_read_server_files,
+pg_write_server_files, or
+pg_execute_server_program, since it allows reading or writing any file or running a program that the server has privileges to access\&.
+.PP
+Do not confuse
+\fBCOPY\fR
+with the
+psql
+instruction
+\fB\ecopy\fR\&.
+\fB\ecopy\fR
+invokes
+\fBCOPY FROM STDIN\fR
+or
+\fBCOPY TO STDOUT\fR, and then fetches/stores the data in a file accessible to the
+psql
+client\&. Thus, file accessibility and access rights depend on the client rather than the server when
+\fB\ecopy\fR
+is used\&.
+.PP
+It is recommended that the file name used in
+\fBCOPY\fR
+always be specified as an absolute path\&. This is enforced by the server in the case of
+\fBCOPY TO\fR, but for
+\fBCOPY FROM\fR
+you do have the option of reading from a file specified by a relative path\&. The path will be interpreted relative to the working directory of the server process (normally the cluster\*(Aqs data directory), not the client\*(Aqs working directory\&.
+.PP
+Executing a command with
+PROGRAM
+might be restricted by the operating system\*(Aqs access control mechanisms, such as SELinux\&.
+.PP
+\fBCOPY FROM\fR
+will invoke any triggers and check constraints on the destination table\&. However, it will not invoke rules\&.
+.PP
+For identity columns, the
+\fBCOPY FROM\fR
+command will always write the column values provided in the input data, like the
+\fBINSERT\fR
+option
+OVERRIDING SYSTEM VALUE\&.
+.PP
+\fBCOPY\fR
+input and output is affected by
+\fIDateStyle\fR\&. To ensure portability to other
+PostgreSQL
+installations that might use non\-default
+\fIDateStyle\fR
+settings,
+\fIDateStyle\fR
+should be set to
+ISO
+before using
+\fBCOPY TO\fR\&. It is also a good idea to avoid dumping data with
+\fIIntervalStyle\fR
+set to
+sql_standard, because negative interval values might be misinterpreted by a server that has a different setting for
+\fIIntervalStyle\fR\&.
+.PP
+Input data is interpreted according to
+ENCODING
+option or the current client encoding, and output data is encoded in
+ENCODING
+or the current client encoding, even if the data does not pass through the client but is read from or written to a file directly by the server\&.
+.PP
+\fBCOPY\fR
+stops operation at the first error\&. This should not lead to problems in the event of a
+\fBCOPY TO\fR, but the target table will already have received earlier rows in a
+\fBCOPY FROM\fR\&. These rows will not be visible or accessible, but they still occupy disk space\&. This might amount to a considerable amount of wasted disk space if the failure happened well into a large copy operation\&. You might wish to invoke
+\fBVACUUM\fR
+to recover the wasted space\&.
+.PP
+FORCE_NULL
+and
+FORCE_NOT_NULL
+can be used simultaneously on the same column\&. This results in converting quoted null strings to null values and unquoted null strings to empty strings\&.
+.SH "FILE FORMATS"
+.SS "Text Format"
+.PP
+When the
+text
+format is used, the data read or written is a text file with one line per table row\&. Columns in a row are separated by the delimiter character\&. The column values themselves are strings generated by the output function, or acceptable to the input function, of each attribute\*(Aqs data type\&. The specified null string is used in place of columns that are null\&.
+\fBCOPY FROM\fR
+will raise an error if any line of the input file contains more or fewer columns than are expected\&.
+.PP
+End of data can be represented by a single line containing just backslash\-period (\e\&.)\&. An end\-of\-data marker is not necessary when reading from a file, since the end of file serves perfectly well; it is needed only when copying data to or from client applications using pre\-3\&.0 client protocol\&.
+.PP
+Backslash characters (\e) can be used in the
+\fBCOPY\fR
+data to quote data characters that might otherwise be taken as row or column delimiters\&. In particular, the following characters
+\fImust\fR
+be preceded by a backslash if they appear as part of a column value: backslash itself, newline, carriage return, and the current delimiter character\&.
+.PP
+The specified null string is sent by
+\fBCOPY TO\fR
+without adding any backslashes; conversely,
+\fBCOPY FROM\fR
+matches the input against the null string before removing backslashes\&. Therefore, a null string such as
+\eN
+cannot be confused with the actual data value
+\eN
+(which would be represented as
+\e\eN)\&.
+.PP
+The following special backslash sequences are recognized by
+\fBCOPY FROM\fR:
+.TS
+allbox tab(:);

+T}
+.TE
+.sp 1
+Presently,
+\fBCOPY TO\fR
+will never emit an octal or hex\-digits backslash sequence, but it does use the other sequences listed above for those control characters\&.
+.PP
+Any other backslashed character that is not mentioned in the above table will be taken to represent itself\&. However, beware of adding backslashes unnecessarily, since that might accidentally produce a string matching the end\-of\-data marker (\e\&.) or the null string (\eN
+by default)\&. These strings will be recognized before any other backslash processing is done\&.
+.PP
+It is strongly recommended that applications generating
+\fBCOPY\fR
+data convert data newlines and carriage returns to the
+\en
+and
+\er
+sequences respectively\&. At present it is possible to represent a data carriage return by a backslash and carriage return, and to represent a data newline by a backslash and newline\&. However, these representations might not be accepted in future releases\&. They are also highly vulnerable to corruption if the
+\fBCOPY\fR
+file is transferred across different machines (for example, from Unix to Windows or vice versa)\&.
+.PP
+All backslash sequences are interpreted after encoding conversion\&. The bytes specified with the octal and hex\-digit backslash sequences must form valid characters in the database encoding\&.
+.PP
+\fBCOPY TO\fR
+will terminate each row with a Unix\-style newline (\(lq\en\(rq)\&. Servers running on Microsoft Windows instead output carriage return/newline (\(lq\er\en\(rq), but only for
+\fBCOPY\fR
+to a server file; for consistency across platforms,
+\fBCOPY TO STDOUT\fR
+always sends
+\(lq\en\(rq
+regardless of server platform\&.
+\fBCOPY FROM\fR
+can handle lines ending with newlines, carriage returns, or carriage return/newlines\&. To reduce the risk of error due to un\-backslashed newlines or carriage returns that were meant as data,
+\fBCOPY FROM\fR
+will complain if the line endings in the input are not all alike\&.
+.SS "CSV Format"
+.PP
+This format option is used for importing and exporting the Comma Separated Value (CSV) file format used by many other programs, such as spreadsheets\&. Instead of the escaping rules used by
+PostgreSQL\*(Aqs standard text format, it produces and recognizes the common CSV escaping mechanism\&.
+.PP
+The values in each record are separated by the
+DELIMITER
+character\&. If the value contains the delimiter character, the
+QUOTE
+character, the
+NULL
+string, a carriage return, or line feed character, then the whole value is prefixed and suffixed by the
+QUOTE
+character, and any occurrence within the value of a
+QUOTE
+character or the
+ESCAPE
+character is preceded by the escape character\&. You can also use
+FORCE_QUOTE
+to force quotes when outputting non\-NULL
+values in specific columns\&.
+.PP
+The
+CSV
+format has no standard way to distinguish a
+NULL
+value from an empty string\&.
+PostgreSQL\*(Aqs
+\fBCOPY\fR
+handles this by quoting\&. A
+NULL
+is output as the
+NULL
+parameter string and is not quoted, while a non\-NULL
+value matching the
+NULL
+parameter string is quoted\&. For example, with the default settings, a
+NULL
+is written as an unquoted empty string, while an empty string data value is written with double quotes ("")\&. Reading values follows similar rules\&. You can use
+FORCE_NOT_NULL
+to prevent
+NULL
+input comparisons for specific columns\&. You can also use
+FORCE_NULL
+to convert quoted null string data values to
+NULL\&.
+.PP
+Because backslash is not a special character in the
+CSV
+format,
+\e\&., the end\-of\-data marker, could also appear as a data value\&. To avoid any misinterpretation, a
+\e\&.
+data value appearing as a lone entry on a line is automatically quoted on output, and on input, if quoted, is not interpreted as the end\-of\-data marker\&. If you are loading a file created by another application that has a single unquoted column and might have a value of
+\e\&., you might need to quote that value in the input file\&.

+Signature
+.RS 4
+11\-byte sequence
+PGCOPY\en\e377\er\en\e0
+\(em note that the zero byte is a required part of the signature\&. (The signature is designed to allow easy identification of files that have been munged by a non\-8\-bit\-clean transfer\&. This signature will be changed by end\-of\-line\-translation filters, dropped zero bytes, dropped high bits, or parity changes\&.)

+Flags field
+.RS 4
+32\-bit integer bit mask to denote important aspects of the file format\&. Bits are numbered from 0 (LSB) to 31 (MSB)\&. Note that this field is stored in network byte order (most significant byte first), as are all the integer fields used in the file format\&. Bits 16\(en31 are reserved to denote critical file format issues; a reader should abort if it finds an unexpected bit set in this range\&. Bits 0\(en15 are reserved to signal backwards\-compatible format issues; a reader should simply ignore any unexpected bits set in this range\&. Currently only one flag bit is defined, and the rest must be zero:

+Header extension area length
+.RS 4
+32\-bit integer, length in bytes of remainder of header, not including self\&. Currently, this is zero, and the first tuple follows immediately\&.

+The header extension area is envisioned to contain a sequence of self\-identifying chunks\&. The flags field is not intended to tell readers what is in the extension area\&. Specific design of header extension contents is left for a later release\&.

+\fBTuples\fR
+.RS 4
+.PP
+Each tuple begins with a 16\-bit integer count of the number of fields in the tuple\&. (Presently, all tuples in a table will have the same count, but that might not always be true\&.) Then, repeated for each field in the tuple, there is a 32\-bit length word followed by that many bytes of field data\&. (The length word does not include itself, and can be zero\&.) As a special case, \-1 indicates a NULL field value\&. No value bytes follow in the NULL case\&.
+.PP
+There is no alignment padding or any other extra data between fields\&.
+.PP
+Presently, all data values in a binary\-format file are assumed to be in binary format (format code one)\&. It is anticipated that a future extension might add a header field that allows per\-column format codes to be specified\&.

+.SH "DESCRIPTION"
+.PP
+\fBCREATE AGGREGATE\fR
+defines a new aggregate function\&.
+\fBCREATE OR REPLACE AGGREGATE\fR
+will either define a new aggregate function or replace an existing definition\&. Some basic and commonly\-used aggregate functions are included with the distribution; they are documented in
+Section\ \&9.21\&. If one defines new types or needs an aggregate function not already provided, then
+\fBCREATE AGGREGATE\fR
+can be used to provide the desired features\&.
+.PP
+When replacing an existing definition, the argument types, result type, and number of direct arguments may not be changed\&. Also, the new definition must be of the same kind (ordinary aggregate, ordered\-set aggregate, or hypothetical\-set aggregate) as the old one\&.
+.PP
+If a schema name is given (for example,
+CREATE AGGREGATE myschema\&.myagg \&.\&.\&.) then the aggregate function is created in the specified schema\&. Otherwise it is created in the current schema\&.
+.PP
+An aggregate function is identified by its name and input data type(s)\&. Two aggregates in the same schema can have the same name if they operate on different input types\&. The name and input data type(s) of an aggregate must also be distinct from the name and input data type(s) of every ordinary function in the same schema\&. This behavior is identical to overloading of ordinary function names (see
+CREATE FUNCTION (\fBCREATE_FUNCTION\fR(7)))\&.
+.PP
+A simple aggregate function is made from one or two ordinary functions: a state transition function
+\fIsfunc\fR, and an optional final calculation function
+\fIffunc\fR\&. These are used as follows:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+\fIsfunc\fR( internal\-state, next\-data\-values ) \-\-\-> next\-internal\-state
+\fIffunc\fR( internal\-state ) \-\-\-> aggregate\-value
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+PostgreSQL
+creates a temporary variable of data type
+\fIstype\fR
+to hold the current internal state of the aggregate\&. At each input row, the aggregate argument value(s) are calculated and the state transition function is invoked with the current state value and the new argument value(s) to calculate a new internal state value\&. After all the rows have been processed, the final function is invoked once to calculate the aggregate\*(Aqs return value\&. If there is no final function then the ending state value is returned as\-is\&.
+.PP
+An aggregate function can provide an initial condition, that is, an initial value for the internal state value\&. This is specified and stored in the database as a value of type
+text, but it must be a valid external representation of a constant of the state value data type\&. If it is not supplied then the state value starts out null\&.
+.PP
+If the state transition function is declared
+\(lqstrict\(rq, then it cannot be called with null inputs\&. With such a transition function, aggregate execution behaves as follows\&. Rows with any null input values are ignored (the function is not called and the previous state value is retained)\&. If the initial state value is null, then at the first row with all\-nonnull input values, the first argument value replaces the state value, and the transition function is invoked at each subsequent row with all\-nonnull input values\&. This is handy for implementing aggregates like
+\fBmax\fR\&. Note that this behavior is only available when
+\fIstate_data_type\fR
+is the same as the first
+\fIarg_data_type\fR\&. When these types are different, you must supply a nonnull initial condition or use a nonstrict transition function\&.
+.PP
+If the state transition function is not strict, then it will be called unconditionally at each input row, and must deal with null inputs and null state values for itself\&. This allows the aggregate author to have full control over the aggregate\*(Aqs handling of null values\&.
+.PP
+If the final function is declared
+\(lqstrict\(rq, then it will not be called when the ending state value is null; instead a null result will be returned automatically\&. (Of course this is just the normal behavior of strict functions\&.) In any case the final function has the option of returning a null value\&. For example, the final function for
+\fBavg\fR
+returns null when it sees there were zero input rows\&.
+.PP
+Sometimes it is useful to declare the final function as taking not just the state value, but extra parameters corresponding to the aggregate\*(Aqs input values\&. The main reason for doing this is if the final function is polymorphic and the state value\*(Aqs data type would be inadequate to pin down the result type\&. These extra parameters are always passed as NULL (and so the final function must not be strict when the
+FINALFUNC_EXTRA
+option is used), but nonetheless they are valid parameters\&. The final function could for example make use of
+\fBget_fn_expr_argtype\fR
+to identify the actual argument type in the current call\&.
+.PP
+An aggregate can optionally support
+moving\-aggregate mode, as described in
+Section\ \&38.12.1\&. This requires specifying the
+MSFUNC,
+MINVFUNC, and
+MSTYPE
+parameters, and optionally the
+MSSPACE,
+MFINALFUNC,
+MFINALFUNC_EXTRA,
+MFINALFUNC_MODIFY, and
+MINITCOND
+parameters\&. Except for
+MINVFUNC, these parameters work like the corresponding simple\-aggregate parameters without
+M; they define a separate implementation of the aggregate that includes an inverse transition function\&.
+.PP
+The syntax with
+ORDER BY
+in the parameter list creates a special type of aggregate called an
+ordered\-set aggregate; or if
+HYPOTHETICAL
+is specified, then a
+hypothetical\-set aggregate
+is created\&. These aggregates operate over groups of sorted values in order\-dependent ways, so that specification of an input sort order is an essential part of a call\&. Also, they can have
+direct
+arguments, which are arguments that are evaluated only once per aggregation rather than once per input row\&. Hypothetical\-set aggregates are a subclass of ordered\-set aggregates in which some of the direct arguments are required to match, in number and data types, the aggregated argument columns\&. This allows the values of those direct arguments to be added to the collection of aggregate\-input rows as an additional
+\(lqhypothetical\(rq
+row\&.
+.PP
+An aggregate can optionally support
+partial aggregation, as described in
+Section\ \&38.12.4\&. This requires specifying the
+COMBINEFUNC
+parameter\&. If the
+\fIstate_data_type\fR
+is
+internal, it\*(Aqs usually also appropriate to provide the
+SERIALFUNC
+and
+DESERIALFUNC
+parameters so that parallel aggregation is possible\&. Note that the aggregate must also be marked
+PARALLEL SAFE
+to enable parallel aggregation\&.
+.PP
+Aggregates that behave like
+\fBMIN\fR
+or
+\fBMAX\fR
+can sometimes be optimized by looking into an index instead of scanning every input row\&. If this aggregate can be so optimized, indicate it by specifying a
+sort operator\&. The basic requirement is that the aggregate must yield the first element in the sort ordering induced by the operator; in other words:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT agg(col) FROM tab;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+must be equivalent to:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT col FROM tab ORDER BY col USING sortop LIMIT 1;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Further assumptions are that the aggregate ignores null inputs, and that it delivers a null result if and only if there were no non\-null inputs\&. Ordinarily, a data type\*(Aqs
+<
+operator is the proper sort operator for
+\fBMIN\fR, and
+>
+is the proper sort operator for
+\fBMAX\fR\&. Note that the optimization will never actually take effect unless the specified operator is the
+\(lqless than\(rq
+or
+\(lqgreater than\(rq
+strategy member of a B\-tree index operator class\&.

+.PP
+In parameters that specify support function names, you can write a schema name if needed, for example
+SFUNC = public\&.sum\&. Do not write argument types there, however \(em the argument types of the support functions are determined from other parameters\&.
+.PP
+Ordinarily, PostgreSQL functions are expected to be true functions that do not modify their input values\&. However, an aggregate transition function,
+\fIwhen used in the context of an aggregate\fR, is allowed to cheat and modify its transition\-state argument in place\&. This can provide substantial performance benefits compared to making a fresh copy of the transition state each time\&.
+.PP
+Likewise, while an aggregate final function is normally expected not to modify its input values, sometimes it is impractical to avoid modifying the transition\-state argument\&. Such behavior must be declared using the
+FINALFUNC_MODIFY
+parameter\&. The
+READ_WRITE
+value indicates that the final function modifies the transition state in unspecified ways\&. This value prevents use of the aggregate as a window function, and it also prevents merging of transition states for aggregate calls that share the same input values and transition functions\&. The
+SHAREABLE
+value indicates that the transition function cannot be applied after the final function, but multiple final\-function calls can be performed on the ending transition state value\&. This value prevents use of the aggregate as a window function, but it allows merging of transition states\&. (That is, the optimization of interest here is not applying the same final function repeatedly, but applying different final functions to the same ending transition state value\&. This is allowed as long as none of the final functions are marked
+READ_WRITE\&.)
+.PP
+If an aggregate supports moving\-aggregate mode, it will improve calculation efficiency when the aggregate is used as a window function for a window with moving frame start (that is, a frame start mode other than
+UNBOUNDED PRECEDING)\&. Conceptually, the forward transition function adds input values to the aggregate\*(Aqs state when they enter the window frame from the bottom, and the inverse transition function removes them again when they leave the frame at the top\&. So, when values are removed, they are always removed in the same order they were added\&. Whenever the inverse transition function is invoked, it will thus receive the earliest added but not yet removed argument value(s)\&. The inverse transition function can assume that at least one row will remain in the current state after it removes the oldest row\&. (When this would not be the case, the window function mechanism simply starts a fresh aggregation, rather than using the inverse transition function\&.)
+.PP
+The forward transition function for moving\-aggregate mode is not allowed to return NULL as the new state value\&. If the inverse transition function returns NULL, this is taken as an indication that the inverse function cannot reverse the state calculation for this particular input, and so the aggregate calculation will be redone from scratch for the current frame starting position\&. This convention allows moving\-aggregate mode to be used in situations where there are some infrequent cases that are impractical to reverse out of the running state value\&.
+.PP
+If no moving\-aggregate implementation is supplied, the aggregate can still be used with moving frames, but
+PostgreSQL
+will recompute the whole aggregation whenever the start of the frame moves\&. Note that whether or not the aggregate supports moving\-aggregate mode,
+PostgreSQL
+can handle a moving frame end without recalculation; this is done by continuing to add new values to the aggregate\*(Aqs state\&. This is why use of an aggregate as a window function requires that the final function be read\-only: it must not damage the aggregate\*(Aqs state value, so that the aggregation can be continued even after an aggregate result value has been obtained for one set of frame boundaries\&.
+.PP
+The syntax for ordered\-set aggregates allows
+VARIADIC
+to be specified for both the last direct parameter and the last aggregated (WITHIN GROUP) parameter\&. However, the current implementation restricts use of
+VARIADIC
+in two ways\&. First, ordered\-set aggregates can only use
+VARIADIC "any", not other variadic array types\&. Second, if the last direct parameter is
+VARIADIC "any", then there can be only one aggregated parameter and it must also be
+VARIADIC "any"\&. (In the representation used in the system catalogs, these two parameters are merged into a single
+VARIADIC "any"
+item, since
+pg_proc
+cannot represent functions with more than one
+VARIADIC
+parameter\&.) If the aggregate is a hypothetical\-set aggregate, the direct arguments that match the
+VARIADIC "any"
+parameter are the hypothetical ones; any preceding parameters represent additional direct arguments that are not constrained to match the aggregated arguments\&.
+.PP
+Currently, ordered\-set aggregates do not need to support moving\-aggregate mode, since they cannot be used as window functions\&.
+.PP
+Partial (including parallel) aggregation is currently not supported for ordered\-set aggregates\&. Also, it will never be used for aggregate calls that include
+DISTINCT
+or
+ORDER BY
+clauses, since those semantics cannot be supported during partial aggregation\&.

+.SH "DESCRIPTION"
+.PP
+\fBCREATE CAST\fR
+defines a new cast\&. A cast specifies how to perform a conversion between two data types\&. For example,
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT CAST(42 AS float8);
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+converts the integer constant 42 to type
+float8
+by invoking a previously specified function, in this case
+float8(int4)\&. (If no suitable cast has been defined, the conversion fails\&.)
+.PP
+Two types can be
+binary coercible, which means that the conversion can be performed
+\(lqfor free\(rq
+without invoking any function\&. This requires that corresponding values use the same internal representation\&. For instance, the types
+text
+and
+varchar
+are binary coercible both ways\&. Binary coercibility is not necessarily a symmetric relationship\&. For example, the cast from
+xml
+to
+text
+can be performed for free in the present implementation, but the reverse direction requires a function that performs at least a syntax check\&. (Two types that are binary coercible both ways are also referred to as binary compatible\&.)
+.PP
+You can define a cast as an
+I/O conversion cast
+by using the
+WITH INOUT
+syntax\&. An I/O conversion cast is performed by invoking the output function of the source data type, and passing the resulting string to the input function of the target data type\&. In many common cases, this feature avoids the need to write a separate cast function for conversion\&. An I/O conversion cast acts the same as a regular function\-based cast; only the implementation is different\&.
+.PP
+By default, a cast can be invoked only by an explicit cast request, that is an explicit
+CAST(\fIx\fR AS \fItypename\fR)
+or
+\fIx\fR::\fItypename\fR
+construct\&.
+.PP
+If the cast is marked
+AS ASSIGNMENT
+then it can be invoked implicitly when assigning a value to a column of the target data type\&. For example, supposing that
+foo\&.f1
+is a column of type
+text, then:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+INSERT INTO foo (f1) VALUES (42);
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+will be allowed if the cast from type
+integer
+to type
+text
+is marked
+AS ASSIGNMENT, otherwise not\&. (We generally use the term
+assignment cast
+to describe this kind of cast\&.)
+.PP
+If the cast is marked
+AS IMPLICIT
+then it can be invoked implicitly in any context, whether assignment or internally in an expression\&. (We generally use the term
+implicit cast
+to describe this kind of cast\&.) For example, consider this query:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT 2 + 4\&.0;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The parser initially marks the constants as being of type
+integer
+and
+numeric
+respectively\&. There is no
+integer
++
+numeric
+operator in the system catalogs, but there is a
+numeric
++
+numeric
+operator\&. The query will therefore succeed if a cast from
+integer
+to
+numeric
+is available and is marked
+AS IMPLICIT
+\(em which in fact it is\&. The parser will apply the implicit cast and resolve the query as if it had been written
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT CAST ( 2 AS numeric ) + 4\&.0;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Now, the catalogs also provide a cast from
+numeric
+to
+integer\&. If that cast were marked
+AS IMPLICIT
+\(em which it is not \(em then the parser would be faced with choosing between the above interpretation and the alternative of casting the
+numeric
+constant to
+integer
+and applying the
+integer
++
+integer
+operator\&. Lacking any knowledge of which choice to prefer, it would give up and declare the query ambiguous\&. The fact that only one of the two casts is implicit is the way in which we teach the parser to prefer resolution of a mixed
+numeric\-and\-integer
+expression as
+numeric; there is no built\-in knowledge about that\&.
+.PP
+It is wise to be conservative about marking casts as implicit\&. An overabundance of implicit casting paths can cause
+PostgreSQL
+to choose surprising interpretations of commands, or to be unable to resolve commands at all because there are multiple possible interpretations\&. A good rule of thumb is to make a cast implicitly invokable only for information\-preserving transformations between types in the same general type category\&. For example, the cast from
+int2
+to
+int4
+can reasonably be implicit, but the cast from
+float8
+to
+int4
+should probably be assignment\-only\&. Cross\-type\-category casts, such as
+text
+to
+int4, are best made explicit\-only\&.

+Sometimes it is necessary for usability or standards\-compliance reasons to provide multiple implicit casts among a set of types, resulting in ambiguity that cannot be avoided as above\&. The parser has a fallback heuristic based on

+if there is none\&. The third argument, if present, must be type
+boolean; it receives
+true
+if the cast is an explicit cast,

+otherwise\&. (Bizarrely, the SQL standard demands different behaviors for explicit and implicit casts in some cases\&. This argument is supplied for functions that must implement such casts\&. It is not recommended that you design your own data types so that this matters\&.)
+.PP
+The return type of a cast function must be identical to or binary\-coercible to the cast\*(Aqs target type\&.
+.PP
+Ordinarily a cast must have different source and target data types\&. However, it is allowed to declare a cast with identical source and target types if it has a cast implementation function with more than one argument\&. This is used to represent type\-specific length coercion functions in the system catalogs\&. The named function is used to coerce a value of the type to the type modifier value given by its second argument\&.
+.PP
+When a cast has different source and target types and a function that takes more than one argument, it supports converting from one type to another and applying a length coercion in a single step\&. When no such entry is available, coercion to a type that uses a type modifier involves two cast steps, one to convert between data types and a second to apply the modifier\&.

+Remember that if you want to be able to convert types both ways you need to declare casts both ways explicitly\&.
+.PP
+It is normally not necessary to create casts between user\-defined types and the standard string types (text,
+varchar, and
+char(\fIn\fR), as well as user\-defined types that are defined to be in the string category)\&.
+PostgreSQL
+provides automatic I/O conversion casts for that\&. The automatic casts to string types are treated as assignment casts, while the automatic casts from string types are explicit\-only\&. You can override this behavior by declaring your own cast to replace an automatic cast, but usually the only reason to do so is if you want the conversion to be more easily invokable than the standard assignment\-only or explicit\-only setting\&. Another possible reason is that you want the conversion to behave differently from the type\*(Aqs I/O function; but that is sufficiently surprising that you should think twice about whether it\*(Aqs a good idea\&. (A small number of the built\-in types do indeed have different behaviors for conversions, mostly because of requirements of the SQL standard\&.)
+.PP
+While not required, it is recommended that you continue to follow this old convention of naming cast implementation functions after the target data type\&. Many users are used to being able to cast data types using a function\-style notation, that is
+\fItypename\fR(\fIx\fR)\&. This notation is in fact nothing more nor less than a call of the cast implementation function; it is not specially treated as a cast\&. If your conversion functions are not named to support this convention then you will have surprised users\&. Since
+PostgreSQL
+allows overloading of the same function name with different argument types, there is no difficulty in having multiple conversion functions from different types that all use the target type\*(Aqs name\&.

+Actually the preceding paragraph is an oversimplification: there are two cases in which a function\-call construct will be treated as a cast request without having matched it to an actual function\&. If a function call
+\fIname\fR(\fIx\fR) does not exactly match any existing function, but
+\fIname\fR
+is the name of a data type and
+pg_cast
+provides a binary\-coercible cast to this type from the type of
+\fIx\fR, then the call will be construed as a binary\-coercible cast\&. This exception is made so that binary\-coercible casts can be invoked using functional syntax, even though they lack any function\&. Likewise, if there is no
+pg_cast
+entry but the cast would be to or from a string type, the call will be construed as an I/O conversion cast\&. This exception allows I/O conversion casts to be invoked using functional syntax\&.

+There is also an exception to the exception: I/O conversion casts from composite types to string types cannot be invoked using functional syntax, but must be written in explicit cast syntax (either

+POSIX), then all encodings are allowed, but for other locale settings there is only one encoding that will work properly\&. (On Windows, however, UTF\-8 encoding can be used with any locale\&.)
+\fBCREATE DATABASE\fR
+will allow superusers to specify
+SQL_ASCII
+encoding regardless of the locale settings, but this choice is deprecated and may result in misbehavior of character\-string functions if data that is not encoding\-compatible with the locale is stored in the database\&.
+.PP
+The encoding and locale settings must match those of the template database, except when
+template0
+is used as template\&. This is because other databases might contain data that does not match the specified encoding, or might contain indexes whose sort ordering is affected by
+LC_COLLATE
+and
+LC_CTYPE\&. Copying such data would result in a database that is corrupt according to the new settings\&.
+template0, however, is known to not contain any data or indexes that would be affected\&.
+.PP
+There is currently no option to use a database locale with nondeterministic comparisons (see
+\fBCREATE COLLATION\fR
+for an explanation)\&. If this is needed, then per\-column collations would need to be used\&.
+.PP
+The
+CONNECTION LIMIT
+option is only enforced approximately; if two new sessions start at about the same time when just one connection
+\(lqslot\(rq
+remains for the database, it is possible that both will fail\&. Also, the limit is not enforced against superusers or background worker processes\&.

+.SH "DESCRIPTION"
+.PP
+\fBCREATE DOMAIN\fR
+creates a new domain\&. A domain is essentially a data type with optional constraints (restrictions on the allowed set of values)\&. The user who defines a domain becomes its owner\&.
+.PP
+If a schema name is given (for example,
+CREATE DOMAIN myschema\&.mydomain \&.\&.\&.) then the domain is created in the specified schema\&. Otherwise it is created in the current schema\&. The domain name must be unique among the types and domains existing in its schema\&.
+.PP
+Domains are useful for abstracting common constraints on fields into a single location for maintenance\&. For example, several tables might contain email address columns, all requiring the same CHECK constraint to verify the address syntax\&. Define a domain rather than setting up each table\*(Aqs constraint individually\&.
+.PP
+To be able to create a domain, you must have
+USAGE
+privilege on the underlying type\&.
+.SH "PARAMETERS"
+.PP
+\fIname\fR
+.RS 4
+The name (optionally schema\-qualified) of a domain to be created\&.
+.RE
+.PP
+\fIdata_type\fR
+.RS 4
+The underlying data type of the domain\&. This can include array specifiers\&.
+.RE
+.PP
+\fIcollation\fR
+.RS 4
+An optional collation for the domain\&. If no collation is specified, the domain has the same collation behavior as its underlying data type\&. The underlying type must be collatable if
+COLLATE
+is specified\&.
+.RE
+.PP
+DEFAULT \fIexpression\fR
+.RS 4
+The
+DEFAULT
+clause specifies a default value for columns of the domain data type\&. The value is any variable\-free expression (but subqueries are not allowed)\&. The data type of the default expression must match the data type of the domain\&. If no default value is specified, then the default value is the null value\&.
+.sp
+The default expression will be used in any insert operation that does not specify a value for the column\&. If a default value is defined for a particular column, it overrides any default associated with the domain\&. In turn, the domain default overrides any default value associated with the underlying data type\&.
+.RE
+.PP
+CONSTRAINT \fIconstraint_name\fR
+.RS 4
+An optional name for a constraint\&. If not specified, the system generates a name\&.
+.RE
+.PP
+NOT NULL
+.RS 4
+Values of this domain are prevented from being null (but see notes below)\&.
+.RE
+.PP
+NULL
+.RS 4
+Values of this domain are allowed to be null\&. This is the default\&.
+.sp
+This clause is only intended for compatibility with nonstandard SQL databases\&. Its use is discouraged in new applications\&.
+.RE
+.PP
+CHECK (\fIexpression\fR)
+.RS 4
+CHECK
+clauses specify integrity constraints or tests which values of the domain must satisfy\&. Each constraint must be an expression producing a Boolean result\&. It should use the key word
+VALUE
+to refer to the value being tested\&. Expressions evaluating to TRUE or UNKNOWN succeed\&. If the expression produces a FALSE result, an error is reported and the value is not allowed to be converted to the domain type\&.
+.sp
+Currently,
+CHECK
+expressions cannot contain subqueries nor refer to variables other than
+VALUE\&.
+.sp
+When a domain has multiple
+CHECK
+constraints, they will be tested in alphabetical order by name\&. (PostgreSQL
+versions before 9\&.5 did not honor any particular firing order for
+CHECK
+constraints\&.)
+.RE
+.SH "NOTES"
+.PP
+Domain constraints, particularly
+NOT NULL, are checked when converting a value to the domain type\&. It is possible for a column that is nominally of the domain type to read as null despite there being such a constraint\&. For example, this can happen in an outer\-join query, if the domain column is on the nullable side of the outer join\&. A more subtle example is
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+INSERT INTO tab (domcol) VALUES ((SELECT domcol FROM tab WHERE false));
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The empty scalar sub\-SELECT will produce a null value that is considered to be of the domain type, so no further constraint checking is applied to it, and the insertion will succeed\&.
+.PP
+It is very difficult to avoid such problems, because of SQL\*(Aqs general assumption that a null value is a valid value of every data type\&. Best practice therefore is to design a domain\*(Aqs constraints so that a null value is allowed, and then to apply column
+NOT NULL
+constraints to columns of the domain type as needed, rather than directly to the domain type\&.
+.PP
+PostgreSQL
+assumes that
+CHECK
+constraints\*(Aq conditions are immutable, that is, they will always give the same result for the same input value\&. This assumption is what justifies examining
+CHECK
+constraints only when a value is first converted to be of a domain type, and not at other times\&. (This is essentially the same as the treatment of table
+CHECK
+constraints, as described in
+Section\ \&5.4.1\&.)
+.PP
+An example of a common way to break this assumption is to reference a user\-defined function in a
+CHECK
+expression, and then change the behavior of that function\&.
+PostgreSQL
+does not disallow that, but it will not notice if there are stored values of the domain type that now violate the
+CHECK
+constraint\&. That would cause a subsequent database dump and restore to fail\&. The recommended way to handle such a change is to drop the constraint (using
+\fBALTER DOMAIN\fR), adjust the function definition, and re\-add the constraint, thereby rechecking it against stored data\&.
+.SH "EXAMPLES"
+.PP
+This example creates the
+us_postal_code
+data type and then uses the type in a table definition\&. A regular expression test is used to verify that the value looks like a valid US postal code:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE DOMAIN us_postal_code AS TEXT
+CHECK(
+   VALUE ~ \*(Aq^\ed{5}$\*(Aq
+OR VALUE ~ \*(Aq^\ed{5}\-\ed{4}$\*(Aq
+);
+
+CREATE TABLE us_snail_addy (
+  address_id SERIAL PRIMARY KEY,
+  street1 TEXT NOT NULL,
+  street2 TEXT,
+  street3 TEXT,
+  city TEXT NOT NULL,
+  postal us_postal_code NOT NULL
+);
+.fi
+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"

+\fBCREATE DOMAIN\fR
+conforms to the SQL standard\&.

+Loading an extension ordinarily requires the same privileges that would be required to create its component objects\&. For many extensions this means superuser privileges are needed\&. However, if the extension is marked

+CREATE
+privilege on the current database\&. In this case the extension object itself will be owned by the calling user, but the contained objects will be owned by the bootstrap superuser (unless the extension\*(Aqs script explicitly assigns them to the calling user)\&.

It is not terribly difficult for a malicious user to create trojan\-horse objects that will compromise later execution of a carelessly\-written extension script, allowing that user to acquire superuser privileges\&. However, trojan\-horse objects are only hazardous if they are in the

+.RE
+.SH "NOTES"
+.PP
+Constraints on foreign tables (such as
+CHECK
+or
+NOT NULL
+clauses) are not enforced by the core
+PostgreSQL
+system, and most foreign data wrappers do not attempt to enforce them either; that is, the constraint is simply assumed to hold true\&. There would be little point in such enforcement since it would only apply to rows inserted or updated via the foreign table, and not to rows modified by other means, such as directly on the remote server\&. Instead, a constraint attached to a foreign table should represent a constraint that is being enforced by the remote server\&.
+.PP
+Some special\-purpose foreign data wrappers might be the only access mechanism for the data they access, and in that case it might be appropriate for the foreign data wrapper itself to perform constraint enforcement\&. But you should not assume that a wrapper does that unless its documentation says so\&.
+.PP
+Although
+PostgreSQL
+does not attempt to enforce constraints on foreign tables, it does assume that they are correct for purposes of query optimization\&. If there are rows visible in the foreign table that do not satisfy a declared constraint, queries on the table might produce errors or incorrect answers\&. It is the user\*(Aqs responsibility to ensure that the constraint definition matches reality\&.

+\fBCaution\fR

+.br
+.PP
+When a foreign table is used as a partition of a partitioned table, there is an implicit constraint that its contents must satisfy the partitioning rule\&. Again, it is the user\*(Aqs responsibility to ensure that that is true, which is best done by installing a matching constraint on the remote server\&.
+.sp .5v
+.RE
+.PP
+Within a partitioned table containing foreign\-table partitions, an
+\fBUPDATE\fR
+that changes the partition key value can cause a row to be moved from a local partition to a foreign\-table partition, provided the foreign data wrapper supports tuple routing\&. However it is not currently possible to move a row from a foreign\-table partition to another partition\&. An
+\fBUPDATE\fR
+that would require doing that will fail due to the partitioning constraint, assuming that that is properly enforced by the remote server\&.
+.PP
+Similar considerations apply to generated columns\&. Stored generated columns are computed on insert or update on the local
+PostgreSQL
+server and handed to the foreign\-data wrapper for writing out to the foreign data store, but it is not enforced that a query of the foreign table returns values for stored generated columns that are consistent with the generation expression\&. Again, this might result in incorrect query results\&.

If this option is given, any call of the function with all\-constant arguments can be immediately replaced with the function value\&.
+.sp
+STABLE
+indicates that the function cannot modify the database, and that within a single table scan it will consistently return the same result for the same argument values, but that its result could change across SQL statements\&. This is the appropriate selection for functions whose results depend on database lookups, parameter variables (such as the current time zone), etc\&. (It is inappropriate for

+\fBcurrent_timestamp\fR
+family of functions qualify as stable, since their values do not change within a transaction\&.
+.sp
+VOLATILE
+indicates that the function value can change even within a single table scan, so no optimizations can be made\&. Relatively few database functions are volatile in this sense; some examples are
+random(),
+currval(),
+timeofday()\&. But note that any function that has side\-effects must be classified volatile, even if its result is quite predictable, to prevent calls from being optimized away; an example is

+LEAKPROOF
+indicates that the function has no side effects\&. It reveals no information about its arguments other than by its return value\&. For example, a function which throws an error message for some argument values but not others, or which includes the argument values in any error message, is not leakproof\&. This affects how the system executes queries against views created with the
+security_barrier
+option or tables with row level security enabled\&. The system will enforce conditions from security policies and security barrier views before any user\-supplied conditions from the query itself that contain non\-leakproof functions, in order to prevent the inadvertent exposure of data\&. Functions and operators marked as leakproof are assumed to be trustworthy, and may be executed before conditions from security policies and security barrier views\&. In addition, functions which do not take arguments or which are not passed any arguments from the security barrier view or table do not have to be marked as leakproof to be executed before security conditions\&.

+PARALLEL SAFE

+.sp
+Functions should be labeled parallel unsafe if they modify any database state, or if they make changes to the transaction such as using sub\-transactions, or if they access sequences or attempt to make persistent changes to settings (e\&.g\&.,
+setval)\&. They should be labeled as parallel restricted if they access temporary tables, client connection state, cursors, prepared statements, or miscellaneous backend\-local state which the system cannot synchronize in parallel mode (e\&.g\&.,
+setseed
+cannot be executed other than by the group leader because a change made by another process would not be reflected in the leader)\&. In general, if a function is labeled as being safe when it is restricted or unsafe, or if it is labeled as being restricted when it is in fact unsafe, it may throw errors or produce wrong answers when used in a parallel query\&. C\-language functions could in theory exhibit totally undefined behavior if mislabeled, since there is no way for the system to protect itself against arbitrary C code, but in most likely cases the result will be no worse than for any other function\&. If in doubt, functions should be labeled as
+UNSAFE, which is the default\&.

+Section\ \&10.3\&.
+.PP
+Two functions are considered the same if they have the same names and
+\fIinput\fR

+is exactly the same as
+CREATE FUNCTION foo (varchar) \&.\&.\&.\&.

+When replacing an existing function with
+\fBCREATE OR REPLACE FUNCTION\fR, there are restrictions on changing parameter names\&. You cannot change the name already assigned to any input parameter (although you can add names to parameters that had none before)\&. If there is more than one output parameter, you cannot change the names of the output parameters, because that would change the column names of the anonymous composite type that describes the function\*(Aqs result\&. These restrictions are made to ensure that existing calls of the function do not stop working when it is replaced\&.

+.SH "WRITING SECURITY DEFINER FUNCTIONS SAFELY"
+.PP
+Because a
+SECURITY DEFINER
+function is executed with the privileges of the user that owns it, care is needed to ensure that the function cannot be misused\&. For security,
+search_path
+should be set to exclude any schemas writable by untrusted users\&. This prevents malicious users from creating objects (e\&.g\&., tables, functions, and operators) that mask objects intended to be used by the function\&. Particularly important in this regard is the temporary\-table schema, which is searched first by default, and is normally writable by anyone\&. A secure arrangement can be obtained by forcing the temporary schema to be searched last\&. To do this, write
+pg_temp
+as the last entry in
+\fIsearch_path\fR\&. This function illustrates safe usage:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE FUNCTION check_password(uname TEXT, pass TEXT)
+RETURNS BOOLEAN AS $$
+DECLARE passed BOOLEAN;
+BEGIN
+        SELECT  (pwd = $2) INTO passed
+        FROM    pwds
+        WHERE   username = $1;
+
+        RETURN passed;
+END;
+$$  LANGUAGE plpgsql
+    SECURITY DEFINER
+    \-\- Set a secure search_path: trusted schema(s), then \*(Aqpg_temp\*(Aq\&.
+    SET search_path = admin, pg_temp;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+This function\*(Aqs intention is to access a table
+admin\&.pwds\&. But without the
+SET
+clause, or with a
+SET
+clause mentioning only
+admin, the function could be subverted by creating a temporary table named
+pwds\&.
+.PP
+Before
+PostgreSQL
+version 8\&.3, the
+SET
+clause was not available, and so older functions may contain rather complicated logic to save, set, and restore
+\fIsearch_path\fR\&. The
+SET
+clause is far easier to use for this purpose\&.
+.PP
+Another point to keep in mind is that by default, execute privilege is granted to
+PUBLIC
+for newly created functions (see
+Section\ \&5.7
+for more information)\&. Frequently you will wish to restrict use of a security definer function to only some users\&. To do that, you must revoke the default
+PUBLIC
+privileges and then grant execute privilege selectively\&. To avoid having a window where the new function is accessible to all, create it and set the privileges within a single transaction\&. For example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+BEGIN;
+CREATE FUNCTION check_password(uname TEXT, pass TEXT) \&.\&.\&. SECURITY DEFINER;
+REVOKE ALL ON FUNCTION check_password(uname TEXT, pass TEXT) FROM PUBLIC;

+\fBCREATE INDEX\fR
+constructs an index on the specified column(s) of the specified relation, which can be a table or a materialized view\&. Indexes are primarily used to enhance database performance (though inappropriate use can result in slower performance)\&.
+.PP
+The key field(s) for the index are specified as column names, or alternatively as expressions written in parentheses\&. Multiple fields can be specified if the index method supports multicolumn indexes\&.
+.PP
+An index field can be an expression computed from the values of one or more columns of the table row\&. This feature can be used to obtain fast access to data based on some transformation of the basic data\&. For example, an index computed on
+upper(col)
+would allow the clause
+WHERE upper(col) = \*(AqJIM\*(Aq
+to use an index\&.
+.PP
+PostgreSQL
+provides the index methods B\-tree, hash, GiST, SP\-GiST, GIN, and BRIN\&. Users can also define their own index methods, but that is fairly complicated\&.
+.PP
+When the
+WHERE
+clause is present, a
+partial index
+is created\&. A partial index is an index that contains entries for only a portion of a table, usually a portion that is more useful for indexing than the rest of the table\&. For example, if you have a table that contains both billed and unbilled orders where the unbilled orders take up a small fraction of the total table and yet that is an often used section, you can improve performance by creating an index on just that portion\&. Another possible application is to use
+WHERE
+with

However, an index\-only scan can return the contents of non\-key columns without having to visit the index\*(Aqs table, since they are available directly from the index entry\&. Thus, addition of non\-key columns allows index\-only scans to be used for queries that otherwise could not use them\&.
+.sp
+It\*(Aqs wise to be conservative about adding non\-key columns to an index, especially wide columns\&. If an index tuple exceeds the maximum size allowed for the index type, data insertion will fail\&.

Furthermore, B\-tree deduplication is never used with indexes that have a non\-key column\&.

+.PP
+fillfactor (integer)
+.RS 4
+The fillfactor for an index is a percentage that determines how full the index method will try to pack index pages\&. For B\-trees, leaf pages are filled to this percentage during initial index builds, and also when extending the index at the right (adding new largest key values)\&. If pages subsequently become completely full, they will be split, leading to fragmentation of the on\-disk index structure\&. B\-trees use a default fillfactor of 90, but any integer value from 10 to 100 can be selected\&.
+.sp
+B\-tree indexes on tables where many inserts and/or updates are anticipated can benefit from lower fillfactor settings at
+\fBCREATE INDEX\fR
+time (following bulk loading into the table)\&. Values in the range of 50 \- 90 can usefully
+\(lqsmooth out\(rq
+the
+\fIrate\fR
+of page splits during the early life of the B\-tree index (lowering fillfactor like this may even lower the absolute number of page splits, though this effect is highly workload dependent)\&. The B\-tree bottom\-up index deletion technique described in
+Section\ \&67.4.2
+is dependent on having some
+\(lqextra\(rq
+space on pages to store
+\(lqextra\(rq
+tuple versions, and so can be affected by fillfactor (though the effect is usually not significant)\&.
+.sp
+In other specific cases it might be useful to increase fillfactor to 100 at
+\fBCREATE INDEX\fR
+time as a way of maximizing space utilization\&. You should only consider this when you are completely sure that the table is static (i\&.e\&. that it will never be affected by either inserts or updates)\&. A fillfactor setting of 100 otherwise risks
+\fIharming\fR
+performance: even a few updates or inserts will cause a sudden flood of page splits\&.

+.SS "Building Indexes Concurrently"
+.PP
+Creating an index can interfere with regular operation of a database\&. Normally
+PostgreSQL
+locks the table to be indexed against writes and performs the entire index build with a single scan of the table\&. Other transactions can still read the table, but if they try to insert, update, or delete rows in the table they will block until the index build is finished\&. This could have a severe effect if the system is a live production database\&. Very large tables can take many hours to be indexed, and even for smaller tables, an index build can lock out writers for periods that are unacceptably long for a production system\&.
+.PP
+PostgreSQL
+supports building indexes without locking out writes\&. This method is invoked by specifying the
+CONCURRENTLY
+option of
+\fBCREATE INDEX\fR\&. When this option is used,
+PostgreSQL
+must perform two scans of the table, and in addition it must wait for all existing transactions that could potentially modify or use the index to terminate\&. Thus this method requires more total work than a standard index build and takes significantly longer to complete\&. However, since it allows normal operations to continue while the index is built, this method is useful for adding new indexes in a production environment\&. Of course, the extra CPU and I/O load imposed by the index creation might slow other operations\&.
+.PP
+In a concurrent index build, the index is actually entered as an
+\(lqinvalid\(rq
+index into the system catalogs in one transaction, then two table scans occur in two more transactions\&. Before each table scan, the index build must wait for existing transactions that have modified the table to terminate\&. After the second scan, the index build must wait for any transactions that have a snapshot (see
+Chapter\ \&13) predating the second scan to terminate, including transactions used by any phase of concurrent index builds on other tables, if the indexes involved are partial or have columns that are not simple column references\&. Then finally the index can be marked
+\(lqvalid\(rq
+and ready for use, and the
+\fBCREATE INDEX\fR
+command terminates\&. Even then, however, the index may not be immediately usable for queries: in the worst case, it cannot be used as long as transactions exist that predate the start of the index build\&.
+.PP
+If a problem arises while scanning the table, such as a deadlock or a uniqueness violation in a unique index, the
+\fBCREATE INDEX\fR
+command will fail but leave behind an
+\(lqinvalid\(rq
+index\&. This index will be ignored for querying purposes because it might be incomplete; however it will still consume update overhead\&. The
+psql
+\fB\ed\fR
+command will report such an index as
+INVALID:
+.sp
+.if n \{\
+.RS 4

+.nf
+postgres=# \ed tab

+Indexes:
+    "idx" btree (col) INVALID
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The recommended recovery method in such cases is to drop the index and try again to perform
+\fBCREATE INDEX CONCURRENTLY\fR\&. (Another possibility is to rebuild the index with
+\fBREINDEX INDEX CONCURRENTLY\fR)\&.
+.PP
+Another caveat when building a unique index concurrently is that the uniqueness constraint is already being enforced against other transactions when the second table scan begins\&. This means that constraint violations could be reported in other queries prior to the index becoming available for use, or even in cases where the index build eventually fails\&. Also, if a failure does occur in the second scan, the
+\(lqinvalid\(rq
+index continues to enforce its uniqueness constraint afterwards\&.
+.PP
+Concurrent builds of expression indexes and partial indexes are supported\&. Errors occurring in the evaluation of these expressions could cause behavior similar to that described above for unique constraint violations\&.
+.PP
+Regular index builds permit other regular index builds on the same table to occur simultaneously, but only one concurrent index build can occur on a table at a time\&. In either case, schema modification of the table is not allowed while the index is being built\&. Another difference is that a regular
+\fBCREATE INDEX\fR
+command can be performed within a transaction block, but
+\fBCREATE INDEX CONCURRENTLY\fR
+cannot\&.
+.PP
+Concurrent builds for indexes on partitioned tables are currently not supported\&. However, you may concurrently build the index on each partition individually and then finally create the partitioned index non\-concurrently in order to reduce the time where writes to the partitioned table will be locked out\&. In this case, building the partitioned index is a metadata only operation\&.
+.SH "NOTES"
+.PP
+See
+Chapter\ \&11
+for information about when indexes can be used, when they are not used, and in which particular situations they can be useful\&.
+.PP
+Currently, only the B\-tree, GiST, GIN, and BRIN index methods support multiple\-key\-column indexes\&. Whether there can be multiple key columns is independent of whether
+INCLUDE
+columns can be added to the index\&. Indexes can have up to 32 columns, including
+INCLUDE
+columns\&. (This limit can be altered when building
+PostgreSQL\&.) Only B\-tree currently supports unique indexes\&.
+.PP
+An
+operator class
+with optional parameters can be specified for each column of an index\&. The operator class identifies the operators to be used by the index for that column\&. For example, a B\-tree index on four\-byte integers would use the
+int4_ops
+class; this operator class includes comparison functions for four\-byte integers\&. In practice the default operator class for the column\*(Aqs data type is usually sufficient\&. The main point of having operator classes is that for some data types, there could be more than one meaningful ordering\&. For example, we might want to sort a complex\-number data type either by absolute value or by real part\&. We could do this by defining two operator classes for the data type and then selecting the proper class when creating an index\&. More information about operator classes is in
+Section\ \&11.10
+and in
+Section\ \&38.16\&.
+.PP
+When
+CREATE INDEX
+is invoked on a partitioned table, the default behavior is to recurse to all partitions to ensure they all have matching indexes\&. Each partition is first checked to determine whether an equivalent index already exists, and if so, that index will become attached as a partition index to the index being created, which will become its parent index\&. If no matching index exists, a new index will be created and automatically attached; the name of the new index in each partition will be determined as if no index name had been specified in the command\&. If the
+ONLY
+option is specified, no recursion is done, and the index is marked invalid\&. (\fBALTER INDEX \&.\&.\&. ATTACH PARTITION\fR
+marks the index valid, once all partitions acquire matching indexes\&.) Note, however, that any partition that is created in the future using
+\fBCREATE TABLE \&.\&.\&. PARTITION OF\fR
+will automatically have a matching index, regardless of whether
+ONLY
+is specified\&.
+.PP
+For index methods that support ordered scans (currently, only B\-tree), the optional clauses
+ASC,
+DESC,
+NULLS FIRST, and/or
+NULLS LAST
+can be specified to modify the sort ordering of the index\&. Since an ordered index can be scanned either forward or backward, it is not normally useful to create a single\-column
+DESC
+index \(em that sort ordering is already available with a regular index\&. The value of these options is that multicolumn indexes can be created that match the sort ordering requested by a mixed\-ordering query, such as
+SELECT \&.\&.\&. ORDER BY x ASC, y DESC\&. The
+NULLS
+options are useful if you need to support
+\(lqnulls sort low\(rq
+behavior, rather than the default
+\(lqnulls sort high\(rq, in queries that depend on indexes to avoid sorting steps\&.
+.PP
+The system regularly collects statistics on all of a table\*(Aqs columns\&. Newly\-created non\-expression indexes can immediately use these statistics to determine an index\*(Aqs usefulness\&. For new expression indexes, it is necessary to run
+\fBANALYZE\fR
+or wait for the
+autovacuum daemon
+to analyze the table to generate statistics for these indexes\&.
+.PP
+For most index methods, the speed of creating an index is dependent on the setting of
+maintenance_work_mem\&. Larger values will reduce the time needed for index creation, so long as you don\*(Aqt make it larger than the amount of memory really available, which would drive the machine into swapping\&.
+.PP
+PostgreSQL
+can build indexes while leveraging multiple CPUs in order to process the table rows faster\&. This feature is known as
+parallel index build\&. For index methods that support building indexes in parallel (currently, only B\-tree),
+\fImaintenance_work_mem\fR
+specifies the maximum amount of memory that can be used by each index build operation as a whole, regardless of how many worker processes were started\&. Generally, a cost model automatically determines how many worker processes should be requested, if any\&.
+.PP
+Parallel index builds may benefit from increasing
+\fImaintenance_work_mem\fR
+where an equivalent serial index build will see little or no benefit\&. Note that
+\fImaintenance_work_mem\fR
+may influence the number of worker processes requested, since parallel workers must have at least a
+32MB
+share of the total
+\fImaintenance_work_mem\fR
+budget\&. There must also be a remaining
+32MB
+share for the leader process\&. Increasing
+max_parallel_maintenance_workers
+may allow more workers to be used, which will reduce the time needed for index creation, so long as the index build is not already I/O bound\&. Of course, there should also be sufficient CPU capacity that would otherwise lie idle\&.
+.PP
+Setting a value for
+parallel_workers
+via
+\fBALTER TABLE\fR
+directly controls how many parallel worker processes will be requested by a
+\fBCREATE INDEX\fR
+against the table\&. This bypasses the cost model completely, and prevents
+\fImaintenance_work_mem\fR

+CREATE [ OR REPLACE ] [ TRUSTED ] [ PROCEDURAL ] LANGUAGE \fIname\fR
+    HANDLER \fIcall_handler\fR [ INLINE \fIinline_handler\fR ] [ VALIDATOR \fIvalfunction\fR ]
+CREATE [ OR REPLACE ] [ TRUSTED ] [ PROCEDURAL ] LANGUAGE \fIname\fR
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBCREATE LANGUAGE\fR
+registers a new procedural language with a
+PostgreSQL
+database\&. Subsequently, functions and procedures can be defined in this new language\&.
+.PP
+\fBCREATE LANGUAGE\fR
+effectively associates the language name with handler function(s) that are responsible for executing functions written in the language\&. Refer to
+Chapter\ \&58
+for more information about language handlers\&.
+.PP
+\fBCREATE OR REPLACE LANGUAGE\fR
+will either create a new language, or replace an existing definition\&. If the language already exists, its parameters are updated according to the command, but the language\*(Aqs ownership and permissions settings do not change, and any existing functions written in the language are assumed to still be valid\&.
+.PP
+One must have the
+PostgreSQL
+superuser privilege to register a new language or change an existing language\*(Aqs parameters\&. However, once the language is created it is valid to assign ownership of it to a non\-superuser, who may then drop it, change its permissions, rename it, or assign it to a new owner\&. (Do not, however, assign ownership of the underlying C functions to a non\-superuser; that would create a privilege escalation path for that user\&.)
+.PP
+The form of
+\fBCREATE LANGUAGE\fR
+that does not supply any handler function is obsolete\&. For backwards compatibility with old dump files, it is interpreted as
+\fBCREATE EXTENSION\fR\&. That will work if the language has been packaged into an extension of the same name, which is the conventional way to set up procedural languages\&.
+.SH "PARAMETERS"
+.PP
+TRUSTED
+.RS 4
+TRUSTED
+specifies that the language does not grant access to data that the user would not otherwise have\&. If this key word is omitted when registering the language, only users with the
+PostgreSQL
+superuser privilege can use this language to create new functions\&.
+.RE
+.PP
+PROCEDURAL
+.RS 4
+This is a noise word\&.
+.RE
+.PP
+\fIname\fR
+.RS 4
+The name of the new procedural language\&. The name must be unique among the languages in the database\&.
+.RE
+.PP
+HANDLER \fIcall_handler\fR
+.RS 4
+\fIcall_handler\fR
+is the name of a previously registered function that will be called to execute the procedural language\*(Aqs functions\&. The call handler for a procedural language must be written in a compiled language such as C with version 1 call convention and registered with
+PostgreSQL
+as a function taking no arguments and returning the
+language_handler
+type, a placeholder type that is simply used to identify the function as a call handler\&.
+.RE
+.PP
+INLINE \fIinline_handler\fR
+.RS 4
+\fIinline_handler\fR
+is the name of a previously registered function that will be called to execute an anonymous code block (\fBDO\fR
+command) in this language\&. If no
+\fIinline_handler\fR
+function is specified, the language does not support anonymous code blocks\&. The handler function must take one argument of type
+internal, which will be the
+\fBDO\fR
+command\*(Aqs internal representation, and it will typically return
+void\&. The return value of the handler is ignored\&.
+.RE
+.PP
+VALIDATOR \fIvalfunction\fR
+.RS 4
+\fIvalfunction\fR
+is the name of a previously registered function that will be called when a new function in the language is created, to validate the new function\&. If no validator function is specified, then a new function will not be checked when it is created\&. The validator function must take one argument of type
+oid, which will be the OID of the to\-be\-created function, and will typically return
+void\&.
+.sp
+A validator function would typically inspect the function body for syntactical correctness, but it can also look at other properties of the function, for example if the language cannot handle certain argument types\&. To signal an error, the validator function should use the
+\fBereport()\fR
+function\&. The return value of the function is ignored\&.
+.RE
+.SH "NOTES"
+.PP
+Use
+\fBDROP LANGUAGE\fR
+to drop procedural languages\&.
+.PP
+The system catalog
+pg_language
+(see
+Section\ \&53.29) records information about the currently installed languages\&. Also, the
+psql
+command
+\fB\edL\fR
+lists the installed languages\&.
+.PP
+To create functions in a procedural language, a user must have the
+USAGE
+privilege for the language\&. By default,
+USAGE
+is granted to
+PUBLIC
+(i\&.e\&., everyone) for trusted languages\&. This can be revoked if desired\&.
+.PP
+Procedural languages are local to individual databases\&. However, a language can be installed into the
+template1
+database, which will cause it to be available automatically in all subsequently\-created databases\&.
+.SH "EXAMPLES"
+.PP
+A minimal sequence for creating a new procedural language is:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE FUNCTION plsample_call_handler() RETURNS language_handler
+    AS \*(Aq$libdir/plsample\*(Aq
+    LANGUAGE C;
+CREATE LANGUAGE plsample
+    HANDLER plsample_call_handler;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Typically that would be written in an extension\*(Aqs creation script, and users would do this to install the extension:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE EXTENSION plsample;
+.fi
+.if n \{\
+.RE

+\fBCREATE OPERATOR CLASS\fR
+creates a new operator class\&. An operator class defines how a particular data type can be used with an index\&. The operator class specifies that certain operators will fill particular roles or
+\(lqstrategies\(rq
+for this data type and this index method\&. The operator class also specifies the support functions to be used by the index method when the operator class is selected for an index column\&. All the operators and functions used by an operator class must be defined before the operator class can be created\&.
+.PP
+If a schema name is given then the operator class is created in the specified schema\&. Otherwise it is created in the current schema\&. Two operator classes in the same schema can have the same name only if they are for different index methods\&.
+.PP
+The user who defines an operator class becomes its owner\&. Presently, the creating user must be a superuser\&. (This restriction is made because an erroneous operator class definition could confuse or even crash the server\&.)

+\fBCREATE OPERATOR CLASS\fR
+does not presently check whether the operator class definition includes all the operators and functions required by the index method, nor whether the operators and functions form a self\-consistent set\&. It is the user\*(Aqs responsibility to define a valid operator class\&.
+.PP
+Related operator classes can be grouped into
+operator families\&. To add a new operator class to an existing family, specify the

+.PP
+Because the index machinery does not check access permissions on functions before using them, including a function or operator in an operator class is tantamount to granting public execute permission on it\&. This is usually not an issue for the sorts of functions that are useful in an operator class\&.
+.PP
+The operators should not be defined by SQL functions\&. An SQL function is likely to be inlined into the calling query, which will prevent the optimizer from recognizing that the query matches an index\&.
+.PP
+Before
+PostgreSQL
+8\&.4, the
+OPERATOR
+clause could include a
+RECHECK
+option\&. This is no longer supported because whether an index operator is
+\(lqlossy\(rq

An operator family defines a collection of related operator classes, and perhaps some additional operators and support functions that are compatible with these operator classes but not essential for the functioning of any individual index\&.

+.fi
+.SH "DESCRIPTION"
+.PP
+The
+\fBCREATE POLICY\fR
+command defines a new row\-level security policy for a table\&. Note that row\-level security must be enabled on the table (using
+\fBALTER TABLE \&.\&.\&. ENABLE ROW LEVEL SECURITY\fR) in order for created policies to be applied\&.
+.PP
+A policy grants the permission to select, insert, update, or delete rows that match the relevant policy expression\&. Existing table rows are checked against the expression specified in
+USING, while new rows that would be created via
+INSERT
+or
+UPDATE
+are checked against the expression specified in
+WITH CHECK\&. When a
+USING
+expression returns true for a given row then that row is visible to the user, while if false or null is returned then the row is not visible\&. When a
+WITH CHECK
+expression returns true for a row then that row is inserted or updated, while if false or null is returned then an error occurs\&.
+.PP
+For
+\fBINSERT\fR,
+\fBUPDATE\fR, and
+\fBMERGE\fR
+statements,
+WITH CHECK
+expressions are enforced after
+BEFORE
+triggers are fired, and before any actual data modifications are made\&. Thus a
+BEFORE ROW
+trigger may modify the data to be inserted, affecting the result of the security policy check\&.
+WITH CHECK
+expressions are enforced before any other constraints\&.
+.PP
+Policy names are per\-table\&. Therefore, one policy name can be used for many different tables and have a definition for each table which is appropriate to that table\&.
+.PP
+Policies can be applied for specific commands or for specific roles\&. The default for newly created policies is that they apply for all commands and roles, unless otherwise specified\&. Multiple policies may apply to a single command; see below for more details\&.
+Table\ \&287
+summarizes how the different types of policy apply to specific commands\&.
+.PP
+For policies that can have both
+USING
+and
+WITH CHECK
+expressions (ALL
+and
+UPDATE), if no
+WITH CHECK
+expression is defined, then the
+USING
+expression will be used both to determine which rows are visible (normal
+USING
+case) and which new rows will be allowed to be added (WITH CHECK
+case)\&.
+.PP
+If row\-level security is enabled for a table, but no applicable policies exist, a
+\(lqdefault deny\(rq
+policy is assumed, so that no rows will be visible or updatable\&.

+.RE
+.PP
+RESTRICTIVE
+.RS 4
+Specify that the policy is to be created as a restrictive policy\&. All restrictive policies which are applicable to a given query will be combined together using the Boolean
+\(lqAND\(rq

+.sp
+Note that there needs to be at least one permissive policy to grant access to records before restrictive policies can be usefully used to reduce that access\&. If only restrictive policies exist, then no records will be accessible\&. When a mix of permissive and restrictive policies are present, a record is only accessible if at least one of the permissive policies passes, in addition to all the restrictive policies\&.

+\fBSELECT\fR), and will not be available for modification (in an
+\fBUPDATE\fR

+\fBDELETE\fR)\&. Such rows are silently suppressed; no error is reported\&.
+.RE
+.PP
+\fIcheck_expression\fR
+.RS 4

+\fBINSERT\fR

+\fBUPDATE\fR
+queries against the table if row\-level security is enabled\&. Only rows for which the expression evaluates to true will be allowed\&. An error will be thrown if the expression evaluates to false or null for any of the records inserted or any of the records that result from the update\&. Note that the
+\fIcheck_expression\fR
+is evaluated against the proposed new contents of the row, not the original contents\&.
+.RE
+.SS "Per\-Command Policies"
+.PP
+ALL
+.RS 4
+Using
+ALL
+for a policy means that it will apply to all commands, regardless of the type of command\&. If an
+ALL
+policy exists and more specific policies exist, then both the
+ALL
+policy and the more specific policy (or policies) will be applied\&. Additionally,
+ALL
+policies will be applied to both the selection side of a query and the modification side, using the
+USING
+expression for both cases if only a
+USING
+expression has been defined\&.
+.sp
+As an example, if an
+UPDATE
+is issued, then the
+ALL
+policy will be applicable both to what the
+UPDATE
+will be able to select as rows to be updated (applying the
+USING
+expression), and to the resulting updated rows, to check if they are permitted to be added to the table (applying the
+WITH CHECK
+expression, if defined, and the
+USING
+expression otherwise)\&. If an
+\fBINSERT\fR
+or
+\fBUPDATE\fR
+command attempts to add rows to the table that do not pass the
+ALL
+policy\*(Aqs
+WITH CHECK
+expression, the entire command will be aborted\&.
+.RE
+.PP
+SELECT
+.RS 4
+Using
+SELECT
+for a policy means that it will apply to
+SELECT
+queries and whenever
+SELECT
+permissions are required on the relation the policy is defined for\&. The result is that only those records from the relation that pass the
+SELECT
+policy will be returned during a
+SELECT
+query, and that queries that require
+SELECT
+permissions, such as
+UPDATE, will also only see those records that are allowed by the
+SELECT
+policy\&. A
+SELECT
+policy cannot have a
+WITH CHECK
+expression, as it only applies in cases where records are being retrieved from the relation\&.
+.RE
+.PP
+INSERT
+.RS 4
+Using
+INSERT
+for a policy means that it will apply to
+INSERT
+commands and
+MERGE
+commands that contain
+INSERT
+actions\&. Rows being inserted that do not pass this policy will result in a policy violation error, and the entire
+INSERT
+command will be aborted\&. An
+INSERT
+policy cannot have a
+USING
+expression, as it only applies in cases where records are being added to the relation\&.
+.sp
+Note that
+INSERT

+ON CONFLICT DO UPDATE
+checks
+INSERT
+policies\*(Aq
+WITH CHECK
+expressions only for rows appended to the relation by the
+INSERT
+path\&.
+.RE
+.PP
+UPDATE
+.RS 4
+Using
+UPDATE
+for a policy means that it will apply to
+UPDATE,
+SELECT FOR UPDATE
+and
+SELECT FOR SHARE
+commands, as well as auxiliary
+ON CONFLICT DO UPDATE
+clauses of
+INSERT
+commands\&.
+MERGE
+commands containing
+UPDATE
+actions are affected as well\&. Since
+UPDATE
+involves pulling an existing record and replacing it with a new modified record,
+UPDATE
+policies accept both a
+USING
+expression and a
+WITH CHECK
+expression\&. The
+USING
+expression determines which records the
+UPDATE
+command will see to operate against, while the
+WITH CHECK
+expression defines which modified rows are allowed to be stored back into the relation\&.
+.sp
+Any rows whose updated values do not pass the
+WITH CHECK
+expression will cause an error, and the entire command will be aborted\&. If only a
+USING
+clause is specified, then that clause will be used for both
+USING
+and
+WITH CHECK
+cases\&.
+.sp
+Typically an
+UPDATE
+command also needs to read data from columns in the relation being updated (e\&.g\&., in a
+WHERE
+clause or a
+RETURNING
+clause, or in an expression on the right hand side of the
+SET
+clause)\&. In this case,
+SELECT
+rights are also required on the relation being updated, and the appropriate
+SELECT
+or
+ALL
+policies will be applied in addition to the
+UPDATE
+policies\&. Thus the user must have access to the row(s) being updated through a
+SELECT
+or
+ALL
+policy in addition to being granted permission to update the row(s) via an
+UPDATE
+or
+ALL
+policy\&.
+.sp
+When an
+INSERT
+command has an auxiliary
+ON CONFLICT DO UPDATE
+clause, if the
+UPDATE
+path is taken, the row to be updated is first checked against the
+USING
+expressions of any
+UPDATE
+policies, and then the new updated row is checked against the
+WITH CHECK
+expressions\&. Note, however, that unlike a standalone
+UPDATE
+command, if the existing row does not pass the
+USING
+expressions, an error will be thrown (the
+UPDATE
+path will
+\fInever\fR
+be silently avoided)\&.

+SELECT
+that are not available for deletion, if they do not pass the
+USING
+expression for the
+DELETE
+policy\&.
+.sp
+In most cases a
+DELETE
+command also needs to read data from columns in the relation that it is deleting from (e\&.g\&., in a

+SELECT
+rights are also required on the relation, and the appropriate

+When multiple policies of different command types apply to the same command (for example,

+AND
+operator\&.
+.PP
+When multiple policies of the same command type apply to the same command, then there must be at least one

+While policies will be applied for explicit queries against tables in the database, they are not applied when the system is performing internal referential integrity checks or validating constraints\&. This means there are indirect ways to determine that a given value exists\&. An example of this is attempting to insert a duplicate value into a column that is a primary key or has a unique constraint\&. If the insert fails then the user can infer that the value already exists\&. (This example assumes that the user is permitted by policy to insert records which they are not allowed to see\&.) Another example is where a user is allowed to insert into a table which references another, otherwise hidden table\&. Existence can be determined by the user inserting values into the referencing table, where success would indicate that the value exists in the referenced table\&. These issues can be addressed by carefully crafting policies to prevent users from being able to insert, delete, or update records at all which might possibly indicate a value they are not otherwise able to see, or by using generated values (e\&.g\&., surrogate keys) instead of keys with external meanings\&.
+.PP
+Generally, the system will enforce filter conditions imposed using security policies prior to qualifications that appear in user queries, in order to prevent inadvertent exposure of the protected data to user\-defined functions which might not be trustworthy\&. However, functions and operators marked by the system (or the system administrator) as
+LEAKPROOF
+may be evaluated before policy expressions, as they are assumed to be trustworthy\&.
+.PP
+Since policy expressions are added to the user\*(Aqs query directly, they will be run with the rights of the user running the overall query\&. Therefore, users who are using a given policy must be able to access any tables or functions referenced in the expression or they will simply receive a permission denied error when attempting to query the table that has row\-level security enabled\&. This does not change how views work, however\&. As with normal queries and views, permission checks and policies for the tables which are referenced by a view will use the view owner\*(Aqs rights and any policies which apply to the view owner, except if the view is defined using the
+security_invoker
+option (see
+\fBCREATE VIEW\fR)\&.
+.PP
+No separate policy exists for
+\fBMERGE\fR\&. Instead, the policies defined for
+\fBSELECT\fR,
+\fBINSERT\fR,
+\fBUPDATE\fR, and
+\fBDELETE\fR
+are applied while executing
+\fBMERGE\fR, depending on the actions that are performed\&.
+.PP
+Additional discussion and practical examples can be found in
+Section\ \&5.8\&.

+.PP
+\fBCREATE PROCEDURE\fR
+defines a new procedure\&.
+\fBCREATE OR REPLACE PROCEDURE\fR
+will either create a new procedure, or replace an existing definition\&. To be able to define a procedure, the user must have the
+USAGE
+privilege on the language\&.
+.PP
+If a schema name is included, then the procedure is created in the specified schema\&. Otherwise it is created in the current schema\&. The name of the new procedure must not match any existing procedure or function with the same input argument types in the same schema\&. However, procedures and functions of different argument types can share a name (this is called
+overloading)\&.
+.PP
+To replace the current definition of an existing procedure, use
+\fBCREATE OR REPLACE PROCEDURE\fR\&. It is not possible to change the name or argument types of a procedure this way (if you tried, you would actually be creating a new, distinct procedure)\&.
+.PP
+When
+\fBCREATE OR REPLACE PROCEDURE\fR
+is used to replace an existing procedure, the ownership and permissions of the procedure do not change\&. All other procedure properties are assigned the values specified or implied in the command\&. You must own the procedure to replace it (this includes being a member of the owning role)\&.
+.PP
+The user that creates the procedure becomes the owner of the procedure\&.
+.PP
+To be able to create a procedure, you must have
+USAGE
+privilege on the argument types\&.
+.PP
+Refer to
+Section\ \&38.4
+for further information on writing procedures\&.
+.SH "PARAMETERS"
+.PP
+\fIname\fR
+.RS 4
+The name (optionally schema\-qualified) of the procedure to create\&.
+.RE
+.PP
+\fIargmode\fR
+.RS 4
+The mode of an argument:
+IN,
+OUT,
+INOUT, or
+VARIADIC\&. If omitted, the default is
+IN\&.
+.RE
+.PP
+\fIargname\fR
+.RS 4
+The name of an argument\&.
+.RE
+.PP
+\fIargtype\fR
+.RS 4
+The data type(s) of the procedure\*(Aqs arguments (optionally schema\-qualified), if any\&. The argument types can be base, composite, or domain types, or can reference the type of a table column\&.
+.sp
+Depending on the implementation language it might also be allowed to specify
+\(lqpseudo\-types\(rq
+such as
+cstring\&. Pseudo\-types indicate that the actual argument type is either incompletely specified, or outside the set of ordinary SQL data types\&.
+.sp
+The type of a column is referenced by writing
+\fItable_name\fR\&.\fIcolumn_name\fR%TYPE\&. Using this feature can sometimes help make a procedure independent of changes to the definition of a table\&.
+.RE
+.PP
+\fIdefault_expr\fR
+.RS 4
+An expression to be used as default value if the parameter is not specified\&. The expression has to be coercible to the argument type of the parameter\&. All input parameters following a parameter with a default value must have default values as well\&.
+.RE
+.PP
+\fIlang_name\fR
+.RS 4
+The name of the language that the procedure is implemented in\&. It can be
+sql,
+c,
+internal, or the name of a user\-defined procedural language, e\&.g\&.,
+plpgsql\&. The default is
+sql
+if
+\fIsql_body\fR
+is specified\&. Enclosing the name in single quotes is deprecated and requires matching case\&.
+.RE
+.PP
+TRANSFORM { FOR TYPE \fItype_name\fR } [, \&.\&.\&. ] }
+.RS 4
+Lists which transforms a call to the procedure should apply\&. Transforms convert between SQL types and language\-specific data types; see
+CREATE TRANSFORM (\fBCREATE_TRANSFORM\fR(7))\&. Procedural language implementations usually have hardcoded knowledge of the built\-in types, so those don\*(Aqt need to be listed here\&. If a procedural language implementation does not know how to handle a type and no transform is supplied, it will fall back to a default behavior for converting data types, but this depends on the implementation\&.
+.RE
+.PP
+[EXTERNAL] SECURITY INVOKER
+.br
+[EXTERNAL] SECURITY DEFINER
+.RS 4
+SECURITY INVOKER
+indicates that the procedure is to be executed with the privileges of the user that calls it\&. That is the default\&.
+SECURITY DEFINER
+specifies that the procedure is to be executed with the privileges of the user that owns it\&.
+.sp
+The key word
+EXTERNAL
+is allowed for SQL conformance, but it is optional since, unlike in SQL, this feature applies to all procedures not only external ones\&.
+.sp
+A
+SECURITY DEFINER
+procedure cannot execute transaction control statements (for example,
+\fBCOMMIT\fR
+and
+\fBROLLBACK\fR, depending on the language)\&.
+.RE
+.PP
+\fIconfiguration_parameter\fR
+.br
+\fIvalue\fR
+.RS 4
+The
+SET
+clause causes the specified configuration parameter to be set to the specified value when the procedure is entered, and then restored to its prior value when the procedure exits\&.
+SET FROM CURRENT
+saves the value of the parameter that is current when
+\fBCREATE PROCEDURE\fR
+is executed as the value to be applied when the procedure is entered\&.
+.sp
+If a
+SET
+clause is attached to a procedure, then the effects of a
+\fBSET LOCAL\fR
+command executed inside the procedure for the same variable are restricted to the procedure: the configuration parameter\*(Aqs prior value is still restored at procedure exit\&. However, an ordinary
+\fBSET\fR
+command (without
+LOCAL) overrides the
+SET
+clause, much as it would do for a previous
+\fBSET LOCAL\fR
+command: the effects of such a command will persist after procedure exit, unless the current transaction is rolled back\&.
+.sp
+If a
+SET
+clause is attached to a procedure, then that procedure cannot execute transaction control statements (for example,
+\fBCOMMIT\fR
+and
+\fBROLLBACK\fR, depending on the language)\&.
+.sp
+See
+\fBSET\fR(7)
+and
+Chapter\ \&20
+for more information about allowed parameter names and values\&.
+.RE
+.PP
+\fIdefinition\fR
+.RS 4
+A string constant defining the procedure; the meaning depends on the language\&. It can be an internal procedure name, the path to an object file, an SQL command, or text in a procedural language\&.
+.sp
+It is often helpful to use dollar quoting (see
+Section\ \&4.1.2.4) to write the procedure definition string, rather than the normal single quote syntax\&. Without dollar quoting, any single quotes or backslashes in the procedure definition must be escaped by doubling them\&.
+.RE
+.PP
+\fIobj_file\fR, \fIlink_symbol\fR
+.RS 4
+This form of the
+AS
+clause is used for dynamically loadable C language procedures when the procedure name in the C language source code is not the same as the name of the SQL procedure\&. The string
+\fIobj_file\fR
+is the name of the shared library file containing the compiled C procedure, and is interpreted as for the
+\fBLOAD\fR
+command\&. The string
+\fIlink_symbol\fR
+is the procedure\*(Aqs link symbol, that is, the name of the procedure in the C language source code\&. If the link symbol is omitted, it is assumed to be the same as the name of the SQL procedure being defined\&.
+.sp
+When repeated
+\fBCREATE PROCEDURE\fR
+calls refer to the same object file, the file is only loaded once per session\&. To unload and reload the file (perhaps during development), start a new session\&.
+.RE
+.PP
+\fIsql_body\fR
+.RS 4
+The body of a
+LANGUAGE SQL
+procedure\&. This should be a block
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+BEGIN ATOMIC
+  \fIstatement\fR;
+  \fIstatement\fR;
+  \&.\&.\&.
+  \fIstatement\fR;
+END
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+This is similar to writing the text of the procedure body as a string constant (see
+\fIdefinition\fR
+above), but there are some differences: This form only works for
+LANGUAGE SQL, the string constant form works for all languages\&. This form is parsed at procedure definition time, the string constant form is parsed at execution time; therefore this form cannot support polymorphic argument types and other constructs that are not resolvable at procedure definition time\&. This form tracks dependencies between the procedure and objects used in the procedure body, so
+DROP \&.\&.\&. CASCADE
+will work correctly, whereas the form using string literals may leave dangling procedures\&. Finally, this form is more compatible with the SQL standard and other SQL implementations\&.

+This clause specifies optional parameters for a publication\&. The following parameters are supported:
+.PP
+publish (string)
+.RS 4
+This parameter determines which DML operations will be published by the new publication to the subscribers\&. The value is comma\-separated list of operations\&. The allowed operations are
+insert,

+This parameter only affects DML operations\&. In particular, the initial data synchronization (see
+Section\ \&31.7.1) for logical replication does not take this parameter into account when copying existing table data\&.
+.RE
+.PP
+publish_via_partition_root (boolean)
+.RS 4
+This parameter determines whether changes in a partitioned table (or on its partitions) contained in the publication will be published using the identity and schema of the partitioned table rather than that of the individual partitions that are actually changed; the latter is the default\&. Enabling this allows the changes to be replicated into a non\-partitioned table or a partitioned table consisting of a different set of partitions\&.
+.sp

+are not specified, then the publication starts out with an empty set of tables\&. That is useful if tables or schemas are to be added later\&.
+.PP
+The creation of a publication does not start replication\&. It only defines a grouping and filtering logic for future subscribers\&.
+.PP
+To create a publication, the invoking user must have the

+To add a table to a publication, the invoking user must have ownership rights on the table\&. The

+defined\&. Otherwise those operations will be disallowed on those tables\&.
+.PP
+Any column list must include the
+REPLICA IDENTITY
+columns in order for
+\fBUPDATE\fR

+operations to be published\&. There are no column list restrictions if the publication publishes only
+\fBINSERT\fR
+operations\&.

+clause) must contain only columns that are covered by the
+REPLICA IDENTITY, in order for
+\fBUPDATE\fR
+and
+\fBDELETE\fR
+operations to be published\&. For publication of
+\fBINSERT\fR
+operations, any column may be used in the
+WHERE
+expression\&. The row filter allows simple expressions that don\*(Aqt have user\-defined functions, user\-defined operators, user\-defined types, user\-defined collations, non\-immutable built\-in functions, or references to system columns\&.
+.PP
+The row filter on a table becomes redundant if
+FOR TABLES IN SCHEMA
+is specified and the table belongs to the referred schema\&.
+.PP
+For published partitioned tables, the row filter for each partition is taken from the published partitioned table if the publication parameter
+publish_via_partition_root
+is true, or from the partition itself if it is false (the default)\&. See
+Section\ \&31.3
+for details about row filters\&. Similarly, for published partitioned tables, the column list for each partition is taken from the published partitioned table if the publication parameter
+publish_via_partition_root
+is true, or from the partition itself if it is false\&.
+.PP
+For an
+\fBINSERT \&.\&.\&. ON CONFLICT\fR
+command, the publication will publish the operation that results from the command\&. Depending on the outcome, it may be published as either
+\fBINSERT\fR
+or
+\fBUPDATE\fR, or it may not be published at all\&.
+.PP
+For a
+\fBMERGE\fR
+command, the publication will publish an
+\fBINSERT\fR,

+\fBDELETE\fR
+for each row inserted, updated, or deleted\&.
+.PP
+\fBATTACH\fRing a table into a partition tree whose root is published using a publication with

+.SH "DESCRIPTION"
+.PP
+\fBCREATE ROLE\fR
+adds a new role to a
+PostgreSQL
+database cluster\&. A role is an entity that can own database objects and have database privileges; a role can be considered a
+\(lquser\(rq, a
+\(lqgroup\(rq, or both depending on how it is used\&. Refer to
+Chapter\ \&22
+and
+Chapter\ \&21
+for information about managing users and authentication\&. You must have
+CREATEROLE
+privilege or be a database superuser to use this command\&.
+.PP
+Note that roles are defined at the database cluster level, and so are valid in all databases in the cluster\&.
+.SH "PARAMETERS"
+.PP
+\fIname\fR
+.RS 4
+The name of the new role\&.
+.RE
+.PP
+SUPERUSER
+.br
+NOSUPERUSER
+.RS 4
+These clauses determine whether the new role is a
+\(lqsuperuser\(rq, who can override all access restrictions within the database\&. Superuser status is dangerous and should be used only when really needed\&. You must yourself be a superuser to create a new superuser\&. If not specified,
+NOSUPERUSER
+is the default\&.
+.RE
+.PP
+CREATEDB
+.br
+NOCREATEDB
+.RS 4
+These clauses define a role\*(Aqs ability to create databases\&. If
+CREATEDB
+is specified, the role being defined will be allowed to create new databases\&. Specifying
+NOCREATEDB
+will deny a role the ability to create databases\&. If not specified,
+NOCREATEDB
+is the default\&.
+.RE
+.PP
+CREATEROLE
+.br
+NOCREATEROLE
+.RS 4
+These clauses determine whether a role will be permitted to create, alter, drop, comment on, change the security label for, and grant or revoke membership in other roles\&. See
+role creation
+for more details about what capabilities are conferred by this privilege\&. If not specified,
+NOCREATEROLE
+is the default\&.
+.RE
+.PP
+INHERIT
+.br
+NOINHERIT
+.RS 4
+These clauses determine whether a role
+\(lqinherits\(rq
+the privileges of roles it is a member of\&. A role with the
+INHERIT
+attribute can automatically use whatever database privileges have been granted to all roles it is directly or indirectly a member of\&. Without
+INHERIT, membership in another role only grants the ability to
+\fBSET ROLE\fR
+to that other role; the privileges of the other role are only available after having done so\&. If not specified,
+INHERIT
+is the default\&.
+.RE
+.PP
+LOGIN
+.br
+NOLOGIN
+.RS 4
+These clauses determine whether a role is allowed to log in; that is, whether the role can be given as the initial session authorization name during client connection\&. A role having the
+LOGIN
+attribute can be thought of as a user\&. Roles without this attribute are useful for managing database privileges, but are not users in the usual sense of the word\&. If not specified,
+NOLOGIN
+is the default, except when
+\fBCREATE ROLE\fR
+is invoked through its alternative spelling
+\fBCREATE USER\fR\&.
+.RE
+.PP
+REPLICATION
+.br
+NOREPLICATION
+.RS 4
+These clauses determine whether a role is a replication role\&. A role must have this attribute (or be a superuser) in order to be able to connect to the server in replication mode (physical or logical replication) and in order to be able to create or drop replication slots\&. A role having the
+REPLICATION
+attribute is a very highly privileged role, and should only be used on roles actually used for replication\&. If not specified,
+NOREPLICATION
+is the default\&. You must be a superuser to create a new role having the
+REPLICATION
+attribute\&.
+.RE
+.PP
+BYPASSRLS
+.br
+NOBYPASSRLS
+.RS 4
+These clauses determine whether a role bypasses every row\-level security (RLS) policy\&.
+NOBYPASSRLS
+is the default\&. You must be a superuser to create a new role having the
+BYPASSRLS
+attribute\&.
+.sp
+Note that pg_dump will set
+row_security
+to
+OFF
+by default, to ensure all contents of a table are dumped out\&. If the user running pg_dump does not have appropriate permissions, an error will be returned\&. However, superusers and the owner of the table being dumped always bypass RLS\&.
+.RE
+.PP
+CONNECTION LIMIT \fIconnlimit\fR
+.RS 4
+If role can log in, this specifies how many concurrent connections the role can make\&. \-1 (the default) means no limit\&. Note that only normal connections are counted towards this limit\&. Neither prepared transactions nor background worker connections are counted towards this limit\&.
+.RE
+.PP
+[ ENCRYPTED ] PASSWORD \*(Aq\fIpassword\fR\*(Aq
+.br
+PASSWORD NULL
+.RS 4
+Sets the role\*(Aqs password\&. (A password is only of use for roles having the
+LOGIN
+attribute, but you can nonetheless define one for roles without it\&.) If you do not plan to use password authentication you can omit this option\&. If no password is specified, the password will be set to null and password authentication will always fail for that user\&. A null password can optionally be written explicitly as
+PASSWORD NULL\&.
+.if n \{\
+.sp
+.\}
+.RS 4
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBNote\fR
+.ps -1
+.br
+Specifying an empty string will also set the password to null, but that was not the case before
+PostgreSQL
+version 10\&. In earlier versions, an empty string could be used, or not, depending on the authentication method and the exact version, and libpq would refuse to use it in any case\&. To avoid the ambiguity, specifying an empty string should be avoided\&.
+.sp .5v
+.RE
+The password is always stored encrypted in the system catalogs\&. The
+ENCRYPTED
+keyword has no effect, but is accepted for backwards compatibility\&. The method of encryption is determined by the configuration parameter
+password_encryption\&. If the presented password string is already in MD5\-encrypted or SCRAM\-encrypted format, then it is stored as\-is regardless of
+\fIpassword_encryption\fR
+(since the system cannot decrypt the specified encrypted password string, to encrypt it in a different format)\&. This allows reloading of encrypted passwords during dump/restore\&.
+.RE
+.PP
+VALID UNTIL \*(Aq\fItimestamp\fR\*(Aq
+.RS 4
+The
+VALID UNTIL
+clause sets a date and time after which the role\*(Aqs password is no longer valid\&. If this clause is omitted the password will be valid for all time\&.
+.RE
+.PP
+IN ROLE \fIrole_name\fR
+.RS 4
+The
+IN ROLE
+clause lists one or more existing roles to which the new role will be immediately added as a new member\&. (Note that there is no option to add the new role as an administrator; use a separate
+\fBGRANT\fR
+command to do that\&.)
+.RE
+.PP
+IN GROUP \fIrole_name\fR
+.RS 4
+IN GROUP
+is an obsolete spelling of
+IN ROLE\&.
+.RE
+.PP
+ROLE \fIrole_name\fR
+.RS 4
+The
+ROLE
+clause lists one or more existing roles which are automatically added as members of the new role\&. (This in effect makes the new role a
+\(lqgroup\(rq\&.)
+.RE
+.PP
+ADMIN \fIrole_name\fR
+.RS 4
+The
+ADMIN
+clause is like
+ROLE, but the named roles are added to the new role
+WITH ADMIN OPTION, giving them the right to grant membership in this role to others\&.
+.RE
+.PP
+USER \fIrole_name\fR
+.RS 4
+The
+USER
+clause is an obsolete spelling of the
+ROLE
+clause\&.
+.RE
+.PP
+SYSID \fIuid\fR
+.RS 4
+The
+SYSID
+clause is ignored, but is accepted for backwards compatibility\&.
+.RE
+.SH "NOTES"
+.PP
+Use
+\fBALTER ROLE\fR
+to change the attributes of a role, and
+\fBDROP ROLE\fR
+to remove a role\&. All the attributes specified by
+\fBCREATE ROLE\fR
+can be modified by later
+\fBALTER ROLE\fR
+commands\&.
+.PP
+The preferred way to add and remove members of roles that are being used as groups is to use
+\fBGRANT\fR
+and
+\fBREVOKE\fR\&.
+.PP
+The
+VALID UNTIL
+clause defines an expiration time for a password only, not for the role per se\&. In particular, the expiration time is not enforced when logging in using a non\-password\-based authentication method\&.
+.PP
+The
+INHERIT
+attribute governs inheritance of grantable privileges (that is, access privileges for database objects and role memberships)\&. It does not apply to the special role attributes set by
+\fBCREATE ROLE\fR
+and
+\fBALTER ROLE\fR\&. For example, being a member of a role with
+CREATEDB
+privilege does not immediately grant the ability to create databases, even if
+INHERIT
+is set; it would be necessary to become that role via
+\fBSET ROLE\fR
+before creating a database\&.
+.PP
+The
+INHERIT
+attribute is the default for reasons of backwards compatibility: in prior releases of
+PostgreSQL, users always had access to all privileges of groups they were members of\&. However,
+NOINHERIT
+provides a closer match to the semantics specified in the SQL standard\&.
+.PP
+Be careful with the
+CREATEROLE
+privilege\&. There is no concept of inheritance for the privileges of a
+CREATEROLE\-role\&. That means that even if a role does not have a certain privilege but is allowed to create other roles, it can easily create another role with different privileges than its own (except for creating roles with superuser privileges)\&. For example, if the role
+\(lquser\(rq
+has the
+CREATEROLE
+privilege but not the
+CREATEDB
+privilege, nonetheless it can create a new role with the
+CREATEDB
+privilege\&. Therefore, regard roles that have the
+CREATEROLE
+privilege as almost\-superuser\-roles\&.
+.PP
+PostgreSQL
+includes a program
+\fBcreateuser\fR(1)
+that has the same functionality as
+\fBCREATE ROLE\fR
+(in fact, it calls this command) but can be run from the command shell\&.
+.PP
+The
+CONNECTION LIMIT
+option is only enforced approximately; if two new sessions start at about the same time when just one connection
+\(lqslot\(rq
+remains for the role, it is possible that both will fail\&. Also, the limit is never enforced for superusers\&.
+.PP
+Caution must be exercised when specifying an unencrypted password with this command\&. The password will be transmitted to the server in cleartext, and it might also be logged in the client\*(Aqs command history or the server log\&. The command
+\fBcreateuser\fR(1), however, transmits the password encrypted\&. Also,
+\fBpsql\fR(1)
+contains a command
+\fB\epassword\fR
+that can be used to safely change the password later\&.
+.SH "EXAMPLES"
+.PP
+Create a role that can log in, but don\*(Aqt give it a password:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf

+\fBCREATE ROLE\fR
+except that it implies

+.PP

+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"
+.PP
+The
+\fBCREATE ROLE\fR
+statement is in the SQL standard, but the standard only requires the syntax
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE ROLE \fIname\fR [ WITH ADMIN \fIrole_name\fR ]
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Multiple initial administrators, and all the other options of
+\fBCREATE ROLE\fR, are
+PostgreSQL
+extensions\&.
+.PP
+The SQL standard defines the concepts of users and roles, but it regards them as distinct concepts and leaves all commands defining users to be specified by each database implementation\&. In
+PostgreSQL
+we have chosen to unify users and roles into a single kind of entity\&. Roles therefore have many more optional attributes than they do in the standard\&.
+.PP
+The behavior specified by the SQL standard is most closely approximated by giving users the
+NOINHERIT
+attribute, while roles are given the
+INHERIT
+attribute\&.

+.fi
+.SH "DESCRIPTION"
+.PP
+\fBCREATE RULE\fR
+defines a new rule applying to a specified table or view\&.
+\fBCREATE OR REPLACE RULE\fR
+will either create a new rule, or replace an existing rule of the same name for the same table\&.
+.PP
+The
+PostgreSQL
+rule system allows one to define an alternative action to be performed on insertions, updates, or deletions in database tables\&. Roughly speaking, a rule causes additional commands to be executed when a given command on a given table is executed\&. Alternatively, an
+INSTEAD
+rule can replace a given command by another, or cause a command not to be executed at all\&. Rules are used to implement SQL views as well\&. It is important to realize that a rule is really a command transformation mechanism, or command macro\&. The transformation happens before the execution of the command starts\&. If you actually want an operation that fires independently for each physical row, you probably want to use a trigger, not a rule\&. More information about the rules system is in
+Chapter\ \&41\&.
+.PP
+Presently,
+ON SELECT
+rules must be unconditional
+INSTEAD
+rules and must have actions that consist of a single
+\fBSELECT\fR
+command\&. Thus, an
+ON SELECT
+rule effectively turns the table into a view, whose visible contents are the rows returned by the rule\*(Aqs
+\fBSELECT\fR
+command rather than whatever had been stored in the table (if anything)\&. It is considered better style to write a
+\fBCREATE VIEW\fR
+command than to create a real table and define an
+ON SELECT
+rule for it\&.
+.PP
+You can create the illusion of an updatable view by defining
+ON INSERT,
+ON UPDATE, and
+ON DELETE
+rules (or any subset of those that\*(Aqs sufficient for your purposes) to replace update actions on the view with appropriate updates on other tables\&. If you want to support
+\fBINSERT RETURNING\fR
+and so on, then be sure to put a suitable
+RETURNING
+clause into each of these rules\&.
+.PP
+There is a catch if you try to use conditional rules for complex view updates: there
+\fImust\fR
+be an unconditional
+INSTEAD
+rule for each action you wish to allow on the view\&. If the rule is conditional, or is not
+INSTEAD, then the system will still reject attempts to perform the update action, because it thinks it might end up trying to perform the action on the dummy table of the view in some cases\&. If you want to handle all the useful cases in conditional rules, add an unconditional
+DO INSTEAD NOTHING
+rule to ensure that the system understands it will never be called on to update the dummy table\&. Then make the conditional rules non\-INSTEAD; in the cases where they are applied, they add to the default
+INSTEAD NOTHING
+action\&. (This method does not currently work to support
+RETURNING
+queries, however\&.)

+A view that is simple enough to be automatically updatable (see

+OLD

+ON UPDATE
+and
+ON DELETE
+rules to refer to the existing row being updated or deleted\&.
+.SH "NOTES"
+.PP
+You must be the owner of a table to create or change rules for it\&.
+.PP
+In a rule for
+INSERT,
+UPDATE, or
+DELETE
+on a view, you can add a
+RETURNING
+clause that emits the view\*(Aqs columns\&. This clause will be used to compute the outputs if the rule is triggered by an
+\fBINSERT RETURNING\fR,
+\fBUPDATE RETURNING\fR, or
+\fBDELETE RETURNING\fR
+command respectively\&. When the rule is triggered by a command without
+RETURNING, the rule\*(Aqs
+RETURNING
+clause will be ignored\&. The current implementation allows only unconditional
+INSTEAD
+rules to contain
+RETURNING; furthermore there can be at most one
+RETURNING
+clause among all the rules for the same event\&. (This ensures that there is only one candidate
+RETURNING
+clause to be used to compute the results\&.)
+RETURNING
+queries on the view will be rejected if there is no
+RETURNING
+clause in any available rule\&.
+.PP
+It is very important to take care to avoid circular rules\&. For example, though each of the following two rule definitions are accepted by
+PostgreSQL, the
+\fBSELECT\fR
+command would cause
+PostgreSQL
+to report an error because of recursive expansion of a rule:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE RULE "_RETURN" AS
+    ON SELECT TO t1
+    DO INSTEAD
+        SELECT * FROM t2;
+
+CREATE RULE "_RETURN" AS
+    ON SELECT TO t2
+    DO INSTEAD
+        SELECT * FROM t1;
+
+SELECT * FROM t1;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Presently, if a rule action contains a
+\fBNOTIFY\fR
+command, the
+\fBNOTIFY\fR
+command will be executed unconditionally, that is, the
+\fBNOTIFY\fR
+will be issued even if there are not any rows that the rule should apply to\&. For example, in:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE RULE notify_me AS ON UPDATE TO mytable DO ALSO NOTIFY mytable;
+
+UPDATE mytable SET name = \*(Aqfoo\*(Aq WHERE id = 42;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+one
+\fBNOTIFY\fR
+event will be sent during the
+\fBUPDATE\fR, whether or not there are any rows that match the condition
+id = 42\&. This is an implementation restriction that might be fixed in future releases\&.

+.PP
+\fBCREATE SCHEMA\fR
+enters a new schema into the current database\&. The schema name must be distinct from the name of any existing schema in the current database\&.
+.PP
+A schema is essentially a namespace: it contains named objects (tables, data types, functions, and operators) whose names can duplicate those of other objects existing in other schemas\&. Named objects are accessed either by
+\(lqqualifying\(rq
+their names with the schema name as a prefix, or by setting a search path that includes the desired schema(s)\&. A
+CREATE
+command specifying an unqualified object name creates the object in the current schema (the one at the front of the search path, which can be determined with the function
+\fBcurrent_schema\fR)\&.
+.PP
+Optionally,
+\fBCREATE SCHEMA\fR
+can include subcommands to create objects within the new schema\&. The subcommands are treated essentially the same as separate commands issued after creating the schema, except that if the
+AUTHORIZATION
+clause is used, all the created objects will be owned by that user\&.
+.SH "PARAMETERS"

+.RE
+.PP
+\fIuser_name\fR
+.RS 4
+The role name of the user who will own the new schema\&. If omitted, defaults to the user executing the command\&. To create a schema owned by another role, you must be a direct or indirect member of that role, or be a superuser\&.
+.RE

+.PP
+According to the SQL standard, the owner of a schema always owns all objects within it\&.
+PostgreSQL
+allows schemas to contain objects owned by users other than the schema owner\&. This can happen only if the schema owner grants the
+CREATE

+    [ OWNED BY { \fItable_name\fR\&.\fIcolumn_name\fR | NONE } ]
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBCREATE SEQUENCE\fR
+creates a new sequence number generator\&. This involves creating and initializing a new special single\-row table with the name
+\fIname\fR\&. The generator will be owned by the user issuing the command\&.
+.PP
+If a schema name is given then the sequence is created in the specified schema\&. Otherwise it is created in the current schema\&. Temporary sequences exist in a special schema, so a schema name cannot be given when creating a temporary sequence\&. The sequence name must be distinct from the name of any other relation (table, sequence, index, view, materialized view, or foreign table) in the same schema\&.
+.PP
+After a sequence is created, you use the functions
+\fBnextval\fR,
+\fBcurrval\fR, and
+\fBsetval\fR
+to operate on the sequence\&. These functions are documented in
+Section\ \&9.17\&.
+.PP
+Although you cannot update a sequence directly, you can use a query like:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT * FROM \fIname\fR;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+to examine the parameters and current state of a sequence\&. In particular, the
+last_value
+field of the sequence shows the last value allocated by any session\&. (Of course, this value might be obsolete by the time it\*(Aqs printed, if other sessions are actively doing
+\fBnextval\fR
+calls\&.)
+.SH "PARAMETERS"
+.PP
+TEMPORARY or TEMP
+.RS 4
+If specified, the sequence object is created only for this session, and is automatically dropped on session exit\&. Existing permanent sequences with the same name are not visible (in this session) while the temporary sequence exists, unless they are referenced with schema\-qualified names\&.
+.RE
+.PP
+UNLOGGED
+.RS 4
+If specified, the sequence is created as an unlogged sequence\&. Changes to unlogged sequences are not written to the write\-ahead log\&. They are not crash\-safe: an unlogged sequence is automatically reset to its initial state after a crash or unclean shutdown\&. Unlogged sequences are also not replicated to standby servers\&.
+.sp
+Unlike unlogged tables, unlogged sequences do not offer a significant performance advantage\&. This option is mainly intended for sequences associated with unlogged tables via identity columns or serial columns\&. In those cases, it usually wouldn\*(Aqt make sense to have the sequence WAL\-logged and replicated but not its associated table\&.
+.RE
+.PP
+IF NOT EXISTS
+.RS 4
+Do not throw an error if a relation with the same name already exists\&. A notice is issued in this case\&. Note that there is no guarantee that the existing relation is anything like the sequence that would have been created \(em it might not even be a sequence\&.
+.RE
+.PP
+\fIname\fR
+.RS 4
+The name (optionally schema\-qualified) of the sequence to be created\&.
+.RE
+.PP
+\fIdata_type\fR
+.RS 4
+The optional clause
+AS \fIdata_type\fR
+specifies the data type of the sequence\&. Valid types are
+smallint,
+integer, and
+bigint\&.
+bigint
+is the default\&. The data type determines the default minimum and maximum values of the sequence\&.
+.RE
+.PP
+\fIincrement\fR
+.RS 4
+The optional clause
+INCREMENT BY \fIincrement\fR
+specifies which value is added to the current sequence value to create a new value\&. A positive value will make an ascending sequence, a negative one a descending sequence\&. The default value is 1\&.
+.RE
+.PP
+\fIminvalue\fR
+.br
+NO MINVALUE
+.RS 4
+The optional clause
+MINVALUE \fIminvalue\fR
+determines the minimum value a sequence can generate\&. If this clause is not supplied or
+\fBNO MINVALUE\fR
+is specified, then defaults will be used\&. The default for an ascending sequence is 1\&. The default for a descending sequence is the minimum value of the data type\&.
+.RE
+.PP
+\fImaxvalue\fR
+.br
+NO MAXVALUE
+.RS 4
+The optional clause
+MAXVALUE \fImaxvalue\fR
+determines the maximum value for the sequence\&. If this clause is not supplied or
+\fBNO MAXVALUE\fR
+is specified, then default values will be used\&. The default for an ascending sequence is the maximum value of the data type\&. The default for a descending sequence is \-1\&.
+.RE
+.PP
+\fIstart\fR
+.RS 4
+The optional clause
+START WITH \fIstart\fR
+allows the sequence to begin anywhere\&. The default starting value is
+\fIminvalue\fR
+for ascending sequences and
+\fImaxvalue\fR
+for descending ones\&.
+.RE
+.PP
+\fIcache\fR
+.RS 4
+The optional clause
+CACHE \fIcache\fR
+specifies how many sequence numbers are to be preallocated and stored in memory for faster access\&. The minimum value is 1 (only one value can be generated at a time, i\&.e\&., no cache), and this is also the default\&.
+.RE
+.PP
+CYCLE
+.br
+NO CYCLE
+.RS 4
+The
+CYCLE
+option allows the sequence to wrap around when the
+\fImaxvalue\fR
+or
+\fIminvalue\fR
+has been reached by an ascending or descending sequence respectively\&. If the limit is reached, the next number generated will be the
+\fIminvalue\fR
+or
+\fImaxvalue\fR, respectively\&.
+.sp
+If
+NO CYCLE
+is specified, any calls to
+\fBnextval\fR
+after the sequence has reached its maximum value will return an error\&. If neither
+CYCLE
+or
+NO CYCLE
+are specified,
+NO CYCLE
+is the default\&.
+.RE
+.PP
+OWNED BY \fItable_name\fR\&.\fIcolumn_name\fR
+.br
+OWNED BY NONE
+.RS 4
+The
+OWNED BY
+option causes the sequence to be associated with a specific table column, such that if that column (or its whole table) is dropped, the sequence will be automatically dropped as well\&. The specified table must have the same owner and be in the same schema as the sequence\&.
+OWNED BY NONE, the default, specifies that there is no such association\&.
+.RE
+.SH "NOTES"
+.PP
+Use
+\fBDROP SEQUENCE\fR
+to remove a sequence\&.
+.PP
+Sequences are based on
+bigint
+arithmetic, so the range cannot exceed the range of an eight\-byte integer (\-9223372036854775808 to 9223372036854775807)\&.
+.PP
+Because
+\fBnextval\fR
+and
+\fBsetval\fR
+calls are never rolled back, sequence objects cannot be used if
+\(lqgapless\(rq
+assignment of sequence numbers is needed\&. It is possible to build gapless assignment by using exclusive locking of a table containing a counter; but this solution is much more expensive than sequence objects, especially if many transactions need sequence numbers concurrently\&.
+.PP
+Unexpected results might be obtained if a
+\fIcache\fR
+setting greater than one is used for a sequence object that will be used concurrently by multiple sessions\&. Each session will allocate and cache successive sequence values during one access to the sequence object and increase the sequence object\*(Aqs
+last_value
+accordingly\&. Then, the next
+\fIcache\fR\-1 uses of
+\fBnextval\fR
+within that session simply return the preallocated values without touching the sequence object\&. So, any numbers allocated but not used within a session will be lost when that session ends, resulting in
+\(lqholes\(rq
+in the sequence\&.
+.PP
+Furthermore, although multiple sessions are guaranteed to allocate distinct sequence values, the values might be generated out of sequence when all the sessions are considered\&. For example, with a
+\fIcache\fR
+setting of 10, session A might reserve values 1\&.\&.10 and return
+\fBnextval\fR=1, then session B might reserve values 11\&.\&.20 and return
+\fBnextval\fR=11 before session A has generated
+\fBnextval\fR=2\&. Thus, with a
+\fIcache\fR
+setting of one it is safe to assume that
+\fBnextval\fR
+values are generated sequentially; with a
+\fIcache\fR
+setting greater than one you should only assume that the
+\fBnextval\fR
+values are all distinct, not that they are generated purely sequentially\&. Also,
+last_value
+will reflect the latest value reserved by any session, whether or not it has yet been returned by
+\fBnextval\fR\&.
+.PP
+Another consideration is that a
+\fBsetval\fR
+executed on such a sequence will not be noticed by other sessions until they have used up any preallocated values they have cached\&.

+.SH "NOTES"
+.PP
+You must be the owner of a table to create a statistics object reading it\&. Once created, however, the ownership of the statistics object is independent of the underlying table(s)\&.
+.PP
+Expression statistics are per\-expression and are similar to creating an index on the expression, except that they avoid the overhead of index maintenance\&. Expression statistics are built automatically for each expression in the statistics object definition\&.
+.PP
+Extended statistics are not currently used by the planner for selectivity estimations made for table joins\&. This limitation will likely be removed in a future version of
+PostgreSQL\&.
+.SH "EXAMPLES"
+.PP
+Create table
+t1
+with two functionally dependent columns, i\&.e\&., knowledge of a value in the first column is sufficient for determining the value in the other column\&. Then functional dependency statistics are built on those columns:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE TABLE t1 (
+    a   int,
+    b   int
+);
+
+INSERT INTO t1 SELECT i/100, i/500
+                 FROM generate_series(1,1000000) s(i);
+
+ANALYZE t1;
+
+\-\- the number of matching rows will be drastically underestimated:
+EXPLAIN ANALYZE SELECT * FROM t1 WHERE (a = 1) AND (b = 0);
+
+CREATE STATISTICS s1 (dependencies) ON a, b FROM t1;
+
+ANALYZE t1;
+
+\-\- now the row count estimate is more accurate:
+EXPLAIN ANALYZE SELECT * FROM t1 WHERE (a = 1) AND (b = 0);
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Without functional\-dependency statistics, the planner would assume that the two
+WHERE
+conditions are independent, and would multiply their selectivities together to arrive at a much\-too\-small row count estimate\&. With such statistics, the planner recognizes that the
+WHERE
+conditions are redundant and does not underestimate the row count\&.
+.PP
+Create table
+t2
+with two perfectly correlated columns (containing identical data), and an MCV list on those columns:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE TABLE t2 (
+    a   int,
+    b   int
+);
+
+INSERT INTO t2 SELECT mod(i,100), mod(i,100)
+                 FROM generate_series(1,1000000) s(i);
+
+CREATE STATISTICS s2 (mcv) ON a, b FROM t2;
+
+ANALYZE t2;
+
+\-\- valid combination (found in MCV)
+EXPLAIN ANALYZE SELECT * FROM t2 WHERE (a = 1) AND (b = 1);
+
+\-\- invalid combination (not found in MCV)
+EXPLAIN ANALYZE SELECT * FROM t2 WHERE (a = 1) AND (b = 2);
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The MCV list gives the planner more detailed information about the specific values that commonly appear in the table, as well as an upper bound on the selectivities of combinations of values that do not appear in the table, allowing it to generate better estimates in both cases\&.
+.PP
+Create table
+t3
+with a single timestamp column, and run queries using expressions on that column\&. Without extended statistics, the planner has no information about the data distribution for the expressions, and uses default estimates\&. The planner also does not realize that the value of the date truncated to the month is fully determined by the value of the date truncated to the day\&. Then expression and ndistinct statistics are built on those two expressions:
+.sp
+.if n \{\

+.nf

+\-\- statistics are built automatically)

+   FROM t3 GROUP BY 1, 2;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Without expression and ndistinct statistics, the planner has no information about the number of distinct values for the expressions, and has to rely on default estimates\&. The equality and range conditions are assumed to have 0\&.5% selectivity, and the number of distinct values in the expression is assumed to be the same as for the column (i\&.e\&. unique)\&. This results in a significant underestimate of the row count in the first two queries\&. Moreover, the planner has no information about the relationship between the expressions, so it assumes the two
+WHERE
+and
+GROUP BY
+conditions are independent, and multiplies their selectivities together to arrive at a severe overestimate of the group count in the aggregate query\&. This is further exacerbated by the lack of accurate statistics for the expressions, forcing the planner to use a default ndistinct estimate for the expression derived from ndistinct for the column\&. With such statistics, the planner recognizes that the conditions are correlated, and arrives at much more accurate estimates\&.

+.SH "DESCRIPTION"
+.PP
+\fBCREATE SUBSCRIPTION\fR
+adds a new logical\-replication subscription\&. The subscription name must be distinct from the name of any existing subscription in the current database\&.
+.PP
+A subscription represents a replication connection to the publisher\&. Hence, in addition to adding definitions in the local catalogs, this command normally creates a replication slot on the publisher\&.
+.PP
+A logical replication worker will be started to replicate data for the new subscription at the commit of the transaction where this command is run, unless the subscription is initially disabled\&.
+.PP
+Additional information about subscriptions and logical replication as a whole is available at
+Section\ \&31.2
+and
+Chapter\ \&31\&.
+.SH "PARAMETERS"
+.PP
+\fIsubscription_name\fR
+.RS 4
+The name of the new subscription\&.
+.RE
+.PP
+CONNECTION \*(Aq\fIconninfo\fR\*(Aq
+.RS 4
+The
+libpq
+connection string defining how to connect to the publisher database\&. For details see
+Section\ \&34.1.1\&.
+.RE
+.PP
+PUBLICATION \fIpublication_name\fR [, \&.\&.\&.]
+.RS 4
+Names of the publications on the publisher to subscribe to\&.
+.RE
+.PP
+WITH ( \fIsubscription_parameter\fR [= \fIvalue\fR] [, \&.\&.\&. ] )
+.RS 4
+This clause specifies optional parameters for a subscription\&.
+.sp
+The following parameters control what happens during subscription creation:
+.PP
+connect (boolean)
+.RS 4
+Specifies whether the
+\fBCREATE SUBSCRIPTION\fR
+command should connect to the publisher at all\&. The default is
+true\&. Setting this to
+false
+will force the values of
+create_slot,
+enabled
+and
+copy_data
+to
+false\&. (You cannot combine setting
+connect
+to
+false
+with setting
+create_slot,
+enabled, or
+copy_data
+to
+true\&.)
+.sp
+Since no connection is made when this option is
+false, no tables are subscribed, and so after you enable the subscription nothing will be replicated\&. You will need to then run
+ALTER SUBSCRIPTION \&.\&.\&. REFRESH PUBLICATION
+for tables to be subscribed\&.
+.RE
+.PP
+create_slot (boolean)
+.RS 4
+Specifies whether the command should create the replication slot on the publisher\&. The default is
+true\&. If set to
+false, you are responsible for creating the publisher\*(Aqs slot in some other way\&.
+.RE
+.PP
+enabled (boolean)
+.RS 4
+Specifies whether the subscription should be actively replicating or whether it should just be set up but not started yet\&. The default is
+true\&.
+.RE
+.PP
+slot_name (string)
+.RS 4
+Name of the publisher\*(Aqs replication slot to use\&. The default is to use the name of the subscription for the slot name\&.
+.sp
+Setting
+slot_name
+to
+NONE
+means there will be no replication slot associated with the subscription\&. Use this when you will be creating the replication slot later manually\&. Such subscriptions must also have both
+enabled
+and
+create_slot
+set to
+false\&.
+.RE
+.sp
+The following parameters control the subscription\*(Aqs replication behavior after it has been created:
+.PP
+binary (boolean)
+.RS 4
+Specifies whether the subscription will request the publisher to send the data in binary format (as opposed to text)\&. The default is
+false\&. Even when this option is enabled, only data types having binary send and receive functions will be transferred in binary\&.
+.sp
+When doing cross\-version replication, it could be that the publisher has a binary send function for some data type, but the subscriber lacks a binary receive function for that type\&. In such a case, data transfer will fail, and the
+binary
+option cannot be used\&.
+.RE
+.PP
+copy_data (boolean)
+.RS 4
+Specifies whether to copy pre\-existing data in the publications that are being subscribed to when the replication starts\&. The default is
+true\&.
+.sp
+If the publications contain
+WHERE
+clauses, it will affect what data is copied\&. Refer to the
+Notes
+for details\&.
+.RE
+.PP
+streaming (boolean)
+.RS 4
+Specifies whether to enable streaming of in\-progress transactions for this subscription\&. By default, all transactions are fully decoded on the publisher and only then sent to the subscriber as a whole\&.
+.RE
+.PP
+synchronous_commit (enum)
+.RS 4
+The value of this parameter overrides the
+synchronous_commit
+setting within this subscription\*(Aqs apply worker processes\&. The default value is
+off\&.
+.sp
+It is safe to use
+off
+for logical replication: If the subscriber loses transactions because of missing synchronization, the data will be sent again from the publisher\&.
+.sp
+A different setting might be appropriate when doing synchronous logical replication\&. The logical replication workers report the positions of writes and flushes to the publisher, and when using synchronous replication, the publisher will wait for the actual flush\&. This means that setting
+synchronous_commit
+for the subscriber to
+off
+when the subscription is used for synchronous replication might increase the latency for
+\fBCOMMIT\fR
+on the publisher\&. In this scenario, it can be advantageous to set
+synchronous_commit
+to
+local
+or higher\&.
+.RE
+.PP
+two_phase (boolean)
+.RS 4
+Specifies whether two\-phase commit is enabled for this subscription\&. The default is
+false\&.
+.sp
+When two\-phase commit is enabled, prepared transactions are sent to the subscriber at the time of
+\fBPREPARE TRANSACTION\fR, and are processed as two\-phase transactions on the subscriber too\&. Otherwise, prepared transactions are sent to the subscriber only when committed, and are then processed immediately by the subscriber\&.
+.sp
+The implementation of two\-phase commit requires that replication has successfully finished the initial table synchronization phase\&. So even when
+two_phase
+is enabled for a subscription, the internal two\-phase state remains temporarily
+\(lqpending\(rq
+until the initialization phase completes\&. See column
+subtwophasestate
+of
+pg_subscription
+to know the actual two\-phase state\&.
+.RE
+.PP
+disable_on_error (boolean)
+.RS 4
+Specifies whether the subscription should be automatically disabled if any errors are detected by subscription workers during data replication from the publisher\&. The default is
+false\&.
+.RE
+.RE
+.SH "NOTES"
+.PP
+See
+Section\ \&31.9
+for details on how to configure access control between the subscription and the publication instance\&.
+.PP
+When creating a replication slot (the default behavior),
+\fBCREATE SUBSCRIPTION\fR
+cannot be executed inside a transaction block\&.
+.PP
+Creating a subscription that connects to the same database cluster (for example, to replicate between databases in the same cluster or to replicate within the same database) will only succeed if the replication slot is not created as part of the same command\&. Otherwise, the
+\fBCREATE SUBSCRIPTION\fR
+call will hang\&. To make this work, create the replication slot separately (using the function
+\fBpg_create_logical_replication_slot\fR
+with the plugin name
+pgoutput) and create the subscription using the parameter
+create_slot = false\&. This is an implementation restriction that might be lifted in a future release\&.
+.PP
+If any table in the publication has a
+WHERE
+clause, rows for which the
+\fIexpression\fR
+evaluates to false or null will not be published\&. If the subscription has several publications in which the same table has been published with different
+WHERE
+clauses, a row will be published if any of the expressions (referring to that publish operation) are satisfied\&. In the case of different
+WHERE
+clauses, if one of the publications has no
+WHERE
+clause (referring to that publish operation) or the publication is declared as
+FOR ALL TABLES
+or
+FOR TABLES IN SCHEMA, rows are always published regardless of the definition of the other expressions\&. If the subscriber is a
+PostgreSQL
+version before 15, then any row filtering is ignored during the initial data synchronization phase\&. For this case, the user might want to consider deleting any initially copied data that would be incompatible with subsequent filtering\&. Because initial data synchronization does not take into account the publication
+publish
+parameter when copying existing table data, some rows may be copied that would not be replicated using DML\&. See
+Section\ \&31.2.2
+for examples\&.
+.PP
+Subscriptions having several publications in which the same table has been published with different column lists are not supported\&.
+.PP
+We allow non\-existent publications to be specified so that users can add those later\&. This means
+pg_subscription
+can have non\-existent publications\&.

+.SH "DESCRIPTION"
+.PP
+\fBCREATE TABLE\fR
+will create a new, initially empty table in the current database\&. The table will be owned by the user issuing the command\&.
+.PP
+If a schema name is given (for example,
+CREATE TABLE myschema\&.mytable \&.\&.\&.) then the table is created in the specified schema\&. Otherwise it is created in the current schema\&. Temporary tables exist in a special schema, so a schema name cannot be given when creating a temporary table\&. The name of the table must be distinct from the name of any other relation (table, sequence, index, view, materialized view, or foreign table) in the same schema\&.
+.PP
+\fBCREATE TABLE\fR
+also automatically creates a data type that represents the composite type corresponding to one row of the table\&. Therefore, tables cannot have the same name as any existing data type in the same schema\&.
+.PP
+The optional constraint clauses specify constraints (tests) that new or updated rows must satisfy for an insert or update operation to succeed\&. A constraint is an SQL object that helps define the set of valid values in the table in various ways\&.
+.PP
+There are two ways to define constraints: table constraints and column constraints\&. A column constraint is defined as part of a column definition\&. A table constraint definition is not tied to a particular column, and it can encompass more than one column\&. Every column constraint can also be written as a table constraint; a column constraint is only a notational convenience for use when the constraint only affects one column\&.
+.PP
+To be able to create a table, you must have
+USAGE
+privilege on all column types or the type in the
+OF
+clause, respectively\&.
+.SH "PARAMETERS"
+.PP
+TEMPORARY or TEMP
+.RS 4
+If specified, the table is created as a temporary table\&. Temporary tables are automatically dropped at the end of a session, or optionally at the end of the current transaction (see
+ON COMMIT
+below)\&. The default search_path includes the temporary schema first and so identically named existing permanent tables are not chosen for new plans while the temporary table exists, unless they are referenced with schema\-qualified names\&. Any indexes created on a temporary table are automatically temporary as well\&.
+.sp
+The
+autovacuum daemon
+cannot access and therefore cannot vacuum or analyze temporary tables\&. For this reason, appropriate vacuum and analyze operations should be performed via session SQL commands\&. For example, if a temporary table is going to be used in complex queries, it is wise to run
+\fBANALYZE\fR
+on the temporary table after it is populated\&.

The contents of an unlogged table are also not replicated to standby servers\&. Any indexes created on an unlogged table are automatically unlogged as well\&.

+.sp
+If the same column name exists in more than one parent table, an error is reported unless the data types of the columns match in each of the parent tables\&. If there is no conflict, then the duplicate columns are merged to form a single column in the new table\&. If the column name list of the new table contains a column name that is also inherited, the data type must likewise match the inherited column(s), and the column definitions are merged into one\&.

Otherwise, any parents that specify default values for the column must all specify the same default, or an error will be reported\&.

+.RS 4
+The optional
+PARTITION BY
+clause specifies a strategy of partitioning the table\&. The table thus created is called a
+partitioned
+table\&. The parenthesized list of columns or expressions forms the
+partition key
+for the table\&. When using range or hash partitioning, the partition key can include multiple columns or expressions (up to 32, but this limit can be altered when building
+PostgreSQL), but for list partitioning, the partition key must consist of a single column or expression\&.
+.sp
+Range and list partitioning require a btree operator class, while hash partitioning requires a hash operator class\&. If no operator class is specified explicitly, the default operator class of the appropriate type will be used; if no default operator class exists, an error will be raised\&. When hash partitioning is used, the operator class used must implement support function 2 (see
+Section\ \&38.16.3

+PARTITION OF \fIparent_table\fR { FOR VALUES \fIpartition_bound_spec\fR | DEFAULT }
+.RS 4
+Creates the table as a
+partition
+of the specified parent table\&. The table can be created either as a partition for specific values using
+FOR VALUES
+or as a default partition using
+DEFAULT\&. Any indexes, constraints and user\-defined row\-level triggers that exist in the parent table are cloned on the new partition\&.
+.sp
+The
+\fIpartition_bound_spec\fR
+must correspond to the partitioning method and partition key of the parent table, and must not overlap with any existing partition of that parent\&. The form with
+IN
+is used for list partitioning, the form with
+FROM

+TO
+is used for range partitioning, and the form with
+WITH
+is used for hash partitioning\&.
+.sp
+\fIpartition_bound_expr\fR
+is any variable\-free expression (subqueries, window functions, aggregate functions, and set\-returning functions are not allowed)\&. Its data type must match the data type of the corresponding partition key column\&. The expression is evaluated once at table creation time, so it can even contain volatile expressions such as
+\fBCURRENT_TIMESTAMP\fR\&.
+.sp
+When creating a list partition,
+NULL
+can be specified to signify that the partition allows the partition key column to be null\&. However, there cannot be more than one such list partition for a given parent table\&.
+NULL
+cannot be specified for range partitions\&.
+.sp
+When creating a range partition, the lower bound specified with
+FROM
+is an inclusive bound, whereas the upper bound specified with
+TO
+is an exclusive bound\&. That is, the values specified in the
+FROM
+list are valid values of the corresponding partition key columns for this partition, whereas those in the
+TO
+list are not\&. Note that this statement must be understood according to the rules of row\-wise comparison (Section\ \&9.24.5)\&. For example, given
+PARTITION BY RANGE (x,y), a partition bound
+FROM (1, 2) TO (3, 4)
+allows
+x=1
+with any
+y>=2,
+x=2
+with any non\-null
+y, and
+x=3
+with any
+y<4\&.
+.sp
+The special values
+MINVALUE
+and
+MAXVALUE
+may be used when creating a range partition to indicate that there is no lower or upper bound on the column\*(Aqs value\&. For example, a partition defined using
+FROM (MINVALUE) TO (10)
+allows any values less than 10, and a partition defined using
+FROM (10) TO (MAXVALUE)
+allows any values greater than or equal to 10\&.
+.sp
+When creating a range partition involving more than one column, it can also make sense to use
+MAXVALUE
+as part of the lower bound, and
+MINVALUE
+as part of the upper bound\&. For example, a partition defined using
+FROM (0, MAXVALUE) TO (10, MAXVALUE)
+allows any rows where the first partition key column is greater than 0 and less than or equal to 10\&. Similarly, a partition defined using
+FROM (\*(Aqa\*(Aq, MINVALUE) TO (\*(Aqb\*(Aq, MINVALUE)
+allows any rows where the first partition key column starts with "a"\&.
+.sp
+Note that if
+MINVALUE
+or
+MAXVALUE
+is used for one column of a partitioning bound, the same value must be used for all subsequent columns\&. For example,
+(10, MINVALUE, 0)
+is not a valid bound; you should write
+(10, MINVALUE, MINVALUE)\&.
+.sp
+Also note that some element types, such as
+timestamp, have a notion of "infinity", which is just another value that can be stored\&. This is different from
+MINVALUE
+and
+MAXVALUE, which are not real values that can be stored, but rather they are ways of saying that the value is unbounded\&.
+MAXVALUE
+can be thought of as being greater than any other value, including "infinity" and
+MINVALUE
+as being less than any other value, including "minus infinity"\&. Thus the range
+FROM (\*(Aqinfinity\*(Aq) TO (MAXVALUE)
+is not an empty range; it allows precisely one value to be stored \(em "infinity"\&.
+.sp
+If
+DEFAULT
+is specified, the table will be created as the default partition of the parent table\&. This option is not available for hash\-partitioned tables\&. A partition key value not fitting into any other partition of the given parent will be routed to the default partition\&.
+.sp
+When a table has an existing
+DEFAULT
+partition and a new partition is added to it, the default partition must be scanned to verify that it does not contain any rows which properly belong in the new partition\&. If the default partition contains a large number of rows, this may be slow\&. The scan will be skipped if the default partition is a foreign table or if it has a constraint which proves that it cannot contain rows which should be placed in the new partition\&.
+.sp
+When creating a hash partition, a modulus and remainder must be specified\&. The modulus must be a positive integer, and the remainder must be a non\-negative integer less than the modulus\&. Typically, when initially setting up a hash\-partitioned table, you should choose a modulus equal to the number of partitions and assign every table the same modulus and a different remainder (see examples, below)\&. However, it is not required that every partition have the same modulus, only that every modulus which occurs among the partitions of a hash\-partitioned table is a factor of the next larger modulus\&. This allows the number of partitions to be increased incrementally without needing to move all the data at once\&. For example, suppose you have a hash\-partitioned table with 8 partitions, each of which has modulus 8, but find it necessary to increase the number of partitions to 16\&. You can detach one of the modulus\-8 partitions, create two new modulus\-16 partitions covering the same portion of the key space (one with a remainder equal to the remainder of the detached partition, and the other with a remainder equal to that value plus 8), and repopulate them with data\&. You can then repeat this \-\- perhaps at a later time \-\- for each modulus\-8 partition until none remain\&. While this may still involve a large amount of data movement at each step, it is still better than having to create a whole new table and move all the data at once\&.
+.sp
+A partition must have the same column names and types as the partitioned table to which it belongs\&. Modifications to the column names or types of a partitioned table will automatically propagate to all partitions\&.
+CHECK
+constraints will be inherited automatically by every partition, but an individual partition may specify additional
+CHECK
+constraints; additional constraints with the same name and condition as in the parent will be merged with the parent constraint\&. Defaults may be specified separately for each partition\&. But note that a partition\*(Aqs default value is not applied when inserting a tuple through a partitioned table\&.
+.sp
+Rows inserted into a partitioned table will be automatically routed to the correct partition\&. If no suitable partition exists, an error will occur\&.
+.sp
+Operations such as
+\fBTRUNCATE\fR
+which normally affect a table and all of its inheritance children will cascade to all partitions, but may also be performed on an individual partition\&.
+.sp
+Note that creating a partition using
+PARTITION OF
+requires taking an
+ACCESS EXCLUSIVE
+lock on the parent partitioned table\&. Likewise, dropping a partition with
+\fBDROP TABLE\fR
+requires taking an
+ACCESS EXCLUSIVE
+lock on the parent table\&. It is possible to use
+\fBALTER TABLE ATTACH/DETACH PARTITION\fR

+The
+EXCLUDE
+clause defines an exclusion constraint, which guarantees that if any two rows are compared on the specified column(s) or expression(s) using the specified operator(s), not all of these comparisons will return
+TRUE\&. If all of the specified operators test for equality, this is equivalent to a
+UNIQUE
+constraint, although an ordinary unique constraint will be faster\&. However, exclusion constraints can specify constraints that are more general than simple equality\&. For example, you can specify a constraint that no two rows in the table contain overlapping circles (see
+Section\ \&8.8) by using the
+&&
+operator\&.
+.sp
+Exclusion constraints are implemented using an index, so each specified operator must be associated with an appropriate operator class (see
+Section\ \&11.10) for the index access method
+\fIindex_method\fR\&. The operators are required to be commutative\&. Each
+\fIexclude_element\fR
+can optionally specify an operator class and/or ordering options; these are described fully under
+CREATE INDEX (\fBCREATE_INDEX\fR(7))\&.
+.sp
+The access method must support
+amgettuple
+(see
+Chapter\ \&64); at present this means
+GIN
+cannot be used\&. Although it\*(Aqs allowed, there is little point in using B\-tree or hash indexes with an exclusion constraint, because this does nothing that an ordinary unique constraint doesn\*(Aqt do better\&. So in practice the access method will always be
+GiST
+or
+SP\-GiST\&.
+.sp
+The
+\fIpredicate\fR
+allows you to specify an exclusion constraint on a subset of the table; internally this creates a partial index\&. Note that parentheses are required around the predicate\&.

+These clauses specify a foreign key constraint, which requires that a group of one or more columns of the new table must only contain values that match values in the referenced column(s) of some row of the referenced table\&. If the
+\fIrefcolumn\fR
+list is omitted, the primary key of the
+\fIreftable\fR
+is used\&. The referenced columns must be the columns of a non\-deferrable unique or primary key constraint in the referenced table\&. The user must have
+REFERENCES
+permission on the referenced table (either the whole table, or the specific referenced columns)\&. The addition of a foreign key constraint requires a
+SHARE ROW EXCLUSIVE
+lock on the referenced table\&. Note that foreign key constraints cannot be defined between temporary tables and permanent tables\&.
+.sp
+A value inserted into the referencing column(s) is matched against the values of the referenced table and referenced columns using the given match type\&. There are three match types:
+MATCH FULL,
+MATCH PARTIAL, and
+MATCH SIMPLE
+(which is the default)\&.
+MATCH FULL
+will not allow one column of a multicolumn foreign key to be null unless all foreign key columns are null; if they are all null, the row is not required to have a match in the referenced table\&.
+MATCH SIMPLE
+allows any of the foreign key columns to be null; if any of them are null, the row is not required to have a match in the referenced table\&.
+MATCH PARTIAL
+is not yet implemented\&. (Of course,
+NOT NULL
+constraints can be applied to the referencing column(s) to prevent these cases from arising\&.)
+.sp
+In addition, when the data in the referenced columns is changed, certain actions are performed on the data in this table\*(Aqs columns\&. The

+.SH "COMPATIBILITY"
+.PP
+The
+\fBCREATE TABLE\fR
+command conforms to the
+SQL
+standard, with exceptions listed below\&.
+.SS "Temporary Tables"
+.PP
+Although the syntax of
+CREATE TEMPORARY TABLE
+resembles that of the SQL standard, the effect is not the same\&. In the standard, temporary tables are defined just once and automatically exist (starting with empty contents) in every session that needs them\&.
+PostgreSQL
+instead requires each session to issue its own
+CREATE TEMPORARY TABLE
+command for each temporary table to be used\&. This allows different sessions to use the same temporary table name for different purposes, whereas the standard\*(Aqs approach constrains all instances of a given temporary table name to have the same table structure\&.
+.PP
+The standard\*(Aqs definition of the behavior of temporary tables is widely ignored\&.
+PostgreSQL\*(Aqs behavior on this point is similar to that of several other SQL databases\&.
+.PP
+The SQL standard also distinguishes between global and local temporary tables, where a local temporary table has a separate set of contents for each SQL module within each session, though its definition is still shared across sessions\&. Since
+PostgreSQL
+does not support SQL modules, this distinction is not relevant in
+PostgreSQL\&.
+.PP
+For compatibility\*(Aqs sake,
+PostgreSQL
+will accept the
+GLOBAL
+and
+LOCAL
+keywords in a temporary table declaration, but they currently have no effect\&. Use of these keywords is discouraged, since future versions of
+PostgreSQL
+might adopt a more standard\-compliant interpretation of their meaning\&.
+.PP
+The
+ON COMMIT
+clause for temporary tables also resembles the SQL standard, but has some differences\&. If the
+ON COMMIT
+clause is omitted, SQL specifies that the default behavior is
+ON COMMIT DELETE ROWS\&. However, the default behavior in
+PostgreSQL
+is
+ON COMMIT PRESERVE ROWS\&. The
+ON COMMIT DROP
+option does not exist in SQL\&.
+.SS "Non\-Deferred Uniqueness Constraints"
+.PP
+When a
+UNIQUE
+or
+PRIMARY KEY
+constraint is not deferrable,
+PostgreSQL
+checks for uniqueness immediately whenever a row is inserted or modified\&. The SQL standard says that uniqueness should be enforced only at the end of the statement; this makes a difference when, for example, a single command updates multiple key values\&. To obtain standard\-compliant behavior, declare the constraint as
+DEFERRABLE
+but not deferred (i\&.e\&.,
+INITIALLY IMMEDIATE)\&. Be aware that this can be significantly slower than immediate uniqueness checking\&.
+.SS "Column Check Constraints"
+.PP
+The SQL standard says that
+CHECK
+column constraints can only refer to the column they apply to; only
+CHECK
+table constraints can refer to multiple columns\&.
+PostgreSQL
+does not enforce this restriction; it treats column and table check constraints alike\&.
+.SS "EXCLUDE Constraint"
+.PP
+The
+EXCLUDE
+constraint type is a
+PostgreSQL
+extension\&.
+.SS "Foreign\-Key Constraint Actions"
+.PP
+The ability to specify column lists in the foreign\-key actions
+SET DEFAULT
+and
+SET NULL
+is a
+PostgreSQL
+extension\&.
+.SS "NULL \(lqConstraint\(rq"
+.PP
+The
+NULL
+\(lqconstraint\(rq
+(actually a non\-constraint) is a
+PostgreSQL
+extension to the SQL standard that is included for compatibility with some other database systems (and for symmetry with the
+NOT NULL
+constraint)\&. Since it is the default for any column, its presence is simply noise\&.
+.SS "Constraint Naming"
+.PP
+The SQL standard says that table and domain constraints must have names that are unique across the schema containing the table or domain\&.
+PostgreSQL
+is laxer: it only requires constraint names to be unique across the constraints attached to a particular table or domain\&. However, this extra freedom does not exist for index\-based constraints (UNIQUE,
+PRIMARY KEY, and
+EXCLUDE
+constraints), because the associated index is named the same as the constraint, and index names must be unique across all relations within the same schema\&.
+.PP
+Currently,
+PostgreSQL
+does not record names for
+NOT NULL
+constraints at all, so they are not subject to the uniqueness restriction\&. This might change in a future release\&.
+.SS "Inheritance"
+.PP
+Multiple inheritance via the
+INHERITS
+clause is a
+PostgreSQL
+language extension\&. SQL:1999 and later define single inheritance using a different syntax and different semantics\&. SQL:1999\-style inheritance is not yet supported by
+PostgreSQL\&.
+.SS "Zero\-Column Tables"
+.PP
+PostgreSQL
+allows a table of no columns to be created (for example,
+CREATE TABLE foo();)\&. This is an extension from the SQL standard, which does not allow zero\-column tables\&. Zero\-column tables are not in themselves very useful, but disallowing them creates odd special cases for
+\fBALTER TABLE DROP COLUMN\fR, so it seems cleaner to ignore this spec restriction\&.
+.SS "Multiple Identity Columns"
+.PP
+PostgreSQL
+allows a table to have more than one identity column\&. The standard specifies that a table can have at most one identity column\&. This is relaxed mainly to give more flexibility for doing schema changes or migrations\&. Note that the
+\fBINSERT\fR
+command supports only one override clause that applies to the entire statement, so having multiple identity columns with different behaviors is not well supported\&.
+.SS "Generated Columns"
+.PP
+The option
+STORED
+is not standard but is also used by other SQL implementations\&. The SQL standard does not specify the storage of generated columns\&.
+.SS "LIKE Clause"
+.PP
+While a
+LIKE
+clause exists in the SQL standard, many of the options that
+PostgreSQL
+accepts for it are not in the standard, and some of the standard\*(Aqs options are not implemented by
+PostgreSQL\&.
+.SS "WITH Clause"
+.PP
+The
+WITH
+clause is a
+PostgreSQL
+extension; storage parameters are not in the standard\&.
+.SS "Tablespaces"
+.PP
+The
+PostgreSQL
+concept of tablespaces is not part of the standard\&. Hence, the clauses
+TABLESPACE
+and
+USING INDEX TABLESPACE
+are extensions\&.
+.SS "Typed Tables"
+.PP
+Typed tables implement a subset of the SQL standard\&. According to the standard, a typed table has columns corresponding to the underlying composite type as well as one other column that is the
+\(lqself\-referencing column\(rq\&.
+PostgreSQL
+does not support self\-referencing columns explicitly\&.
+.SS "PARTITION BY Clause"
+.PP
+The
+PARTITION BY
+clause is a
+PostgreSQL
+extension\&.
+.SS "PARTITION OF Clause"
+.PP
+The
+PARTITION OF
+clause is a
+PostgreSQL
+extension\&.

+.SH "DESCRIPTION"
+.PP
+\fBCREATE TRANSFORM\fR
+defines a new transform\&.
+\fBCREATE OR REPLACE TRANSFORM\fR
+will either create a new transform, or replace an existing definition\&.
+.PP
+A transform specifies how to adapt a data type to a procedural language\&. For example, when writing a function in PL/Python using the
+hstore
+type, PL/Python has no prior knowledge how to present
+hstore
+values in the Python environment\&. Language implementations usually default to using the text representation, but that is inconvenient when, for example, an associative array or a list would be more appropriate\&.
+.PP
+A transform specifies two functions:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+A
+\(lqfrom SQL\(rq
+function that converts the type from the SQL environment to the language\&. This function will be invoked on the arguments of a function written in the language\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+A
+\(lqto SQL\(rq
+function that converts the type from the language to the SQL environment\&. This function will be invoked on the return value of a function written in the language\&.
+.RE
+.sp
+It is not necessary to provide both of these functions\&. If one is not specified, the language\-specific default behavior will be used if necessary\&. (To prevent a transformation in a certain direction from happening at all, you could also write a transform function that always errors out\&.)
+.PP
+To be able to create a transform, you must own and have
+USAGE
+privilege on the type, have
+USAGE
+privilege on the language, and own and have
+EXECUTE
+privilege on the from\-SQL and to\-SQL functions, if specified\&.
+.SH "PARAMETERS"
+.PP
+\fItype_name\fR
+.RS 4
+The name of the data type of the transform\&.

+.RS 4
+The name of the language of the transform\&.
+.RE
+.PP
+\fIfrom_sql_function_name\fR[(\fIargument_type\fR [, \&.\&.\&.])]
+.RS 4
+The name of the function for converting the type from the SQL environment to the language\&. It must take one argument of type
+internal
+and return type
+internal\&. The actual argument will be of the type for the transform, and the function should be coded as if it were\&. (But it is not allowed to declare an SQL\-level function returning
+internal
+without at least one argument of type
+internal\&.) The actual return value will be something specific to the language implementation\&. If no argument list is specified, the function name must be unique in its schema\&.
+.RE

+and return the type that is the type for the transform\&. The actual argument value will be something specific to the language implementation\&. If no argument list is specified, the function name must be unique in its schema\&.
+.RE
+.SH "NOTES"
+.PP
+Use
+\fBDROP TRANSFORM\fR
+to remove transforms\&.
+.SH "EXAMPLES"
+.PP
+To create a transform for type
+hstore
+and language
+plpython3u, first set up the type and the language:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE TYPE hstore \&.\&.\&.;
+
+CREATE EXTENSION plpython3u;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Then create the necessary functions:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE FUNCTION hstore_to_plpython(val internal) RETURNS internal
+LANGUAGE C STRICT IMMUTABLE
+AS \&.\&.\&.;
+
+CREATE FUNCTION plpython_to_hstore(val internal) RETURNS hstore
+LANGUAGE C STRICT IMMUTABLE
+AS \&.\&.\&.;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+And finally create the transform to connect them all together:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE TRANSFORM FOR hstore LANGUAGE plpython3u (
+    FROM SQL WITH FUNCTION hstore_to_plpython(internal),
+    TO SQL WITH FUNCTION plpython_to_hstore(internal)
+);
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+In practice, these commands would be wrapped up in an extension\&.

+section contains a number of extensions that provide transforms, which can serve as real\-world examples\&.
+.SH "COMPATIBILITY"
+.PP
+This form of

+.SH "DESCRIPTION"
+.PP
+\fBCREATE TRIGGER\fR
+creates a new trigger\&.
+\fBCREATE OR REPLACE TRIGGER\fR
+will either create a new trigger, or replace an existing trigger\&. The trigger will be associated with the specified table, view, or foreign table and will execute the specified function
+\fIfunction_name\fR
+when certain operations are performed on that table\&.
+.PP
+To replace the current definition of an existing trigger, use
+\fBCREATE OR REPLACE TRIGGER\fR, specifying the existing trigger\*(Aqs name and parent table\&. All other properties are replaced\&.
+.PP
+The trigger can be specified to fire before the operation is attempted on a row (before constraints are checked and the
+\fBINSERT\fR,
+\fBUPDATE\fR, or
+\fBDELETE\fR
+is attempted); or after the operation has completed (after constraints are checked and the
+\fBINSERT\fR,
+\fBUPDATE\fR, or
+\fBDELETE\fR
+has completed); or instead of the operation (in the case of inserts, updates or deletes on a view)\&. If the trigger fires before or instead of the event, the trigger can skip the operation for the current row, or change the row being inserted (for
+\fBINSERT\fR
+and
+\fBUPDATE\fR
+operations only)\&. If the trigger fires after the event, all changes, including the effects of other triggers, are
+\(lqvisible\(rq
+to the trigger\&.
+.PP
+A trigger that is marked
+FOR EACH ROW
+is called once for every row that the operation modifies\&. For example, a
+\fBDELETE\fR
+that affects 10 rows will cause any
+ON DELETE
+triggers on the target relation to be called 10 separate times, once for each deleted row\&. In contrast, a trigger that is marked
+FOR EACH STATEMENT
+only executes once for any given operation, regardless of how many rows it modifies (in particular, an operation that modifies zero rows will still result in the execution of any applicable
+FOR EACH STATEMENT
+triggers)\&.
+.PP
+Triggers that are specified to fire
+INSTEAD OF

+Also, a trigger definition can specify a Boolean
+WHEN
+condition, which will be tested to see whether the trigger should be fired\&. In row\-level triggers the
+WHEN
+condition can examine the old and/or new values of columns of the row\&. Statement\-level triggers can also have
+WHEN
+conditions, although the feature is not so useful for them since the condition cannot refer to any values in the table\&.
+.PP
+If multiple triggers of the same kind are defined for the same event, they will be fired in alphabetical order by name\&.
+.PP
+When the
+CONSTRAINT
+option is specified, this command creates a
+constraint trigger\&.
+This is the same as a regular trigger except that the timing of the trigger firing can be adjusted using
+\fBSET CONSTRAINTS\fR\&. Constraint triggers must be
+AFTER ROW
+triggers on plain tables (not foreign tables)\&. They can be fired either at the end of the statement causing the triggering event, or at the end of the containing transaction; in the latter case they are said to be
+deferred\&. A pending deferred\-trigger firing can also be forced to happen immediately by using
+\fBSET CONSTRAINTS\fR\&. Constraint triggers are expected to raise an exception when the constraints they implement are violated\&.
+.PP
+The
+REFERENCING
+option enables collection of
+transition relations, which are row sets that include all of the rows inserted, deleted, or modified by the current SQL statement\&. This feature lets the trigger see a global view of what the statement did, not just one row at a time\&. This option is only allowed for an
+AFTER
+trigger that is not a constraint trigger; also, if the trigger is an
+UPDATE
+trigger, it must not specify a
+\fIcolumn_name\fR
+list\&.
+OLD TABLE
+may only be specified once, and only for a trigger that can fire on
+UPDATE
+or
+DELETE; it creates a transition relation containing the
+before\-images
+of all rows updated or deleted by the statement\&. Similarly,
+NEW TABLE

+UPDATE
+or
+INSERT; it creates a transition relation containing the
+after\-images
+of all rows updated or inserted by the statement\&.

+.RE
+.SH "NOTES"
+.PP
+To create or replace a trigger on a table, the user must have the
+TRIGGER
+privilege on the table\&. The user must also have
+EXECUTE
+privilege on the trigger function\&.
+.PP
+Use
+\fBDROP TRIGGER\fR
+to remove a trigger\&.
+.PP
+Creating a row\-level trigger on a partitioned table will cause an identical
+\(lqclone\(rq
+trigger to be created on each of its existing partitions; and any partitions created or attached later will have an identical trigger, too\&. If there is a conflictingly\-named trigger on a child partition already, an error occurs unless
+\fBCREATE OR REPLACE TRIGGER\fR
+is used, in which case that trigger is replaced with a clone trigger\&. When a partition is detached from its parent, its clone triggers are removed\&.
+.PP
+A column\-specific trigger (one defined using the
+UPDATE OF \fIcolumn_name\fR
+syntax) will fire when any of its columns are listed as targets in the
+\fBUPDATE\fR
+command\*(Aqs
+SET
+list\&. It is possible for a column\*(Aqs value to change even when the trigger is not fired, because changes made to the row\*(Aqs contents by
+BEFORE UPDATE
+triggers are not considered\&. Conversely, a command such as
+UPDATE \&.\&.\&. SET x = x \&.\&.\&.
+will fire a trigger on column
+x, even though the column\*(Aqs value did not change\&.
+.PP
+In a
+BEFORE
+trigger, the
+WHEN
+condition is evaluated just before the function is or would be executed, so using
+WHEN
+is not materially different from testing the same condition at the beginning of the trigger function\&. Note in particular that the
+NEW
+row seen by the condition is the current value, as possibly modified by earlier triggers\&. Also, a
+BEFORE
+trigger\*(Aqs
+WHEN
+condition is not allowed to examine the system columns of the
+NEW
+row (such as
+ctid), because those won\*(Aqt have been set yet\&.
+.PP
+In an
+AFTER
+trigger, the
+WHEN
+condition is evaluated just after the row update occurs, and it determines whether an event is queued to fire the trigger at the end of statement\&. So when an
+AFTER
+trigger\*(Aqs
+WHEN
+condition does not return true, it is not necessary to queue an event nor to re\-fetch the row at end of statement\&. This can result in significant speedups in statements that modify many rows, if the trigger only needs to be fired for a few of the rows\&.
+.PP
+In some cases it is possible for a single SQL command to fire more than one kind of trigger\&. For instance an
+\fBINSERT\fR
+with an
+ON CONFLICT DO UPDATE
+clause may cause both insert and update operations, so it will fire both kinds of triggers as needed\&. The transition relations supplied to triggers are specific to their event type; thus an
+\fBINSERT\fR
+trigger will see only the inserted rows, while an
+\fBUPDATE\fR
+trigger will see only the updated rows\&.
+.PP
+Row updates or deletions caused by foreign\-key enforcement actions, such as
+ON UPDATE CASCADE
+or
+ON DELETE SET NULL, are treated as part of the SQL command that caused them (note that such actions are never deferred)\&. Relevant triggers on the affected table will be fired, so that this provides another way in which an SQL command might fire triggers not directly matching its type\&. In simple cases, triggers that request transition relations will see all changes caused in their table by a single original SQL command as a single transition relation\&. However, there are cases in which the presence of an
+AFTER ROW
+trigger that requests transition relations will cause the foreign\-key enforcement actions triggered by a single SQL command to be split into multiple steps, each with its own transition relation(s)\&. In such cases, any statement\-level triggers that are present will be fired once per creation of a transition relation set, ensuring that the triggers see each affected row in a transition relation once and only once\&.
+.PP
+Statement\-level triggers on a view are fired only if the action on the view is handled by a row\-level
+INSTEAD OF
+trigger\&. If the action is handled by an
+INSTEAD
+rule, then whatever statements are emitted by the rule are executed in place of the original statement naming the view, so that the triggers that will be fired are those on tables named in the replacement statements\&. Similarly, if the view is automatically updatable, then the action is handled by automatically rewriting the statement into an action on the view\*(Aqs base table, so that the base table\*(Aqs statement\-level triggers are the ones that are fired\&.
+.PP
+Modifying a partitioned table or a table with inheritance children fires statement\-level triggers attached to the explicitly named table, but not statement\-level triggers for its partitions or child tables\&. In contrast, row\-level triggers are fired on the rows in affected partitions or child tables, even if they are not explicitly named in the query\&. If a statement\-level trigger has been defined with transition relations named by a
+REFERENCING
+clause, then before and after images of rows are visible from all affected partitions or child tables\&. In the case of inheritance children, the row images include only columns that are present in the table that the trigger is attached to\&.
+.PP
+Currently, row\-level triggers with transition relations cannot be defined on partitions or inheritance child tables\&. Also, triggers on partitioned tables may not be
+INSTEAD OF\&.
+.PP
+Currently, the
+OR REPLACE
+option is not supported for constraint triggers\&.
+.PP
+Replacing an existing trigger within a transaction that has already performed updating actions on the trigger\*(Aqs table is not recommended\&. Trigger firing decisions, or portions of firing decisions, that have already been made will not be reconsidered, so the effects could be surprising\&.
+.PP
+There are a few built\-in trigger functions that can be used to solve common problems without having to write your own trigger code; see

+.SH "DESCRIPTION"
+.PP
+\fBCREATE TYPE\fR
+registers a new data type for use in the current database\&. The user who defines a type becomes its owner\&.
+.PP
+If a schema name is given then the type is created in the specified schema\&. Otherwise it is created in the current schema\&. The type name must be distinct from the name of any existing type or domain in the same schema\&. (Because tables have associated data types, the type name must also be distinct from the name of any existing table in the same schema\&.)
+.PP
+There are five forms of
+\fBCREATE TYPE\fR, as shown in the syntax synopsis above\&. They respectively create a
+composite type, an
+enum type, a
+range type, a
+base type, or a
+shell type\&. The first four of these are discussed in turn below\&. A shell type is simply a placeholder for a type to be defined later; it is created by issuing
+\fBCREATE TYPE\fR
+with no parameters except for the type name\&. Shell types are needed as forward references when creating range types and base types, as discussed in those sections\&.
+.SS "Composite Types"
+.PP
+The first form of
+\fBCREATE TYPE\fR
+creates a composite type\&. The composite type is specified by a list of attribute names and data types\&. An attribute\*(Aqs collation can be specified too, if its data type is collatable\&. A composite type is essentially the same as the row type of a table, but using
+\fBCREATE TYPE\fR
+avoids the need to create an actual table when all that is wanted is to define a type\&. A stand\-alone composite type is useful, for example, as the argument or return type of a function\&.
+.PP
+To be able to create a composite type, you must have
+USAGE
+privilege on all attribute types\&.
+.SS "Enumerated Types"
+.PP
+The second form of
+\fBCREATE TYPE\fR
+creates an enumerated (enum) type, as described in
+Section\ \&8.7\&. Enum types take a list of quoted labels, each of which must be less than
+NAMEDATALEN
+bytes long (64 bytes in a standard
+PostgreSQL
+build)\&. (It is possible to create an enumerated type with zero labels, but such a type cannot be used to hold values before at least one label is added using
+\fBALTER TYPE\fR\&.)
+.SS "Range Types"
+.PP
+The third form of
+\fBCREATE TYPE\fR
+creates a new range type, as described in
+Section\ \&8.17\&.
+.PP
+The range type\*(Aqs
+\fIsubtype\fR
+can be any type with an associated b\-tree operator class (to determine the ordering of values for the range type)\&. Normally the subtype\*(Aqs default b\-tree operator class is used to determine ordering; to use a non\-default operator class, specify its name with
+\fIsubtype_opclass\fR\&. If the subtype is collatable, and you want to use a non\-default collation in the range\*(Aqs ordering, specify the desired collation with the
+\fIcollation\fR
+option\&.
+.PP
+The optional
+\fIcanonical\fR
+function must take one argument of the range type being defined, and return a value of the same type\&. This is used to convert range values to a canonical form, when applicable\&. See
+Section\ \&8.17.8
+for more information\&. Creating a
+\fIcanonical\fR
+function is a bit tricky, since it must be defined before the range type can be declared\&. To do this, you must first create a shell type, which is a placeholder type that has no properties except a name and an owner\&. This is done by issuing the command
+CREATE TYPE \fIname\fR, with no additional parameters\&. Then the function can be declared using the shell type as argument and result, and finally the range type can be declared using the same name\&. This automatically replaces the shell type entry with a valid range type\&.
+.PP
+The optional
+\fIsubtype_diff\fR
+function must take two values of the
+\fIsubtype\fR
+type as argument, and return a
+double precision
+value representing the difference between the two given values\&. While this is optional, providing it allows much greater efficiency of GiST indexes on columns of the range type\&. See
+Section\ \&8.17.8
+for more information\&.
+.PP
+The optional
+\fImultirange_type_name\fR
+parameter specifies the name of the corresponding multirange type\&. If not specified, this name is chosen automatically as follows\&. If the range type name contains the substring
+range, then the multirange type name is formed by replacement of the
+range
+substring with
+multirange
+in the range type name\&. Otherwise, the multirange type name is formed by appending a
+_multirange
+suffix to the range type name\&.
+.SS "Base Types"
+.PP
+The fourth form of
+\fBCREATE TYPE\fR
+creates a new base type (scalar type)\&. To create a new base type, you must be a superuser\&. (This restriction is made because an erroneous type definition could confuse or even crash the server\&.)
+.PP
+The parameters can appear in any order, not only that illustrated above, and most are optional\&. You must register two or more functions (using
+\fBCREATE FUNCTION\fR) before defining the type\&. The support functions
+\fIinput_function\fR
+and
+\fIoutput_function\fR
+are required, while the functions
+\fIreceive_function\fR,
+\fIsend_function\fR,
+\fItype_modifier_input_function\fR,
+\fItype_modifier_output_function\fR,
+\fIanalyze_function\fR, and
+\fIsubscript_function\fR
+are optional\&. Generally these functions have to be coded in C or another low\-level language\&.
+.PP
+The
+\fIinput_function\fR
+converts the type\*(Aqs external textual representation to the internal representation used by the operators and functions defined for the type\&.
+\fIoutput_function\fR
+performs the reverse transformation\&. The input function can be declared as taking one argument of type
+cstring, or as taking three arguments of types
+cstring,
+oid,
+integer\&. The first argument is the input text as a C string, the second argument is the type\*(Aqs own OID (except for array types, which instead receive their element type\*(Aqs OID), and the third is the
+typmod
+of the destination column, if known (\-1 will be passed if not)\&. The input function must return a value of the data type itself\&. Usually, an input function should be declared STRICT; if it is not, it will be called with a NULL first parameter when reading a NULL input value\&. The function must still return NULL in this case, unless it raises an error\&. (This case is mainly meant to support domain input functions, which might need to reject NULL inputs\&.) The output function must be declared as taking one argument of the new data type\&. The output function must return type
+cstring\&. Output functions are not invoked for NULL values\&.
+.PP
+The optional
+\fIreceive_function\fR
+converts the type\*(Aqs external binary representation to the internal representation\&. If this function is not supplied, the type cannot participate in binary input\&. The binary representation should be chosen to be cheap to convert to internal form, while being reasonably portable\&. (For example, the standard integer data types use network byte order as the external binary representation, while the internal representation is in the machine\*(Aqs native byte order\&.) The receive function should perform adequate checking to ensure that the value is valid\&. The receive function can be declared as taking one argument of type
+internal, or as taking three arguments of types
+internal,
+oid,
+integer\&. The first argument is a pointer to a
+StringInfo
+buffer holding the received byte string; the optional arguments are the same as for the text input function\&. The receive function must return a value of the data type itself\&. Usually, a receive function should be declared STRICT; if it is not, it will be called with a NULL first parameter when reading a NULL input value\&. The function must still return NULL in this case, unless it raises an error\&. (This case is mainly meant to support domain receive functions, which might need to reject NULL inputs\&.) Similarly, the optional
+\fIsend_function\fR
+converts from the internal representation to the external binary representation\&. If this function is not supplied, the type cannot participate in binary output\&. The send function must be declared as taking one argument of the new data type\&. The send function must return type
+bytea\&. Send functions are not invoked for NULL values\&.
+.PP
+You should at this point be wondering how the input and output functions can be declared to have results or arguments of the new type, when they have to be created before the new type can be created\&. The answer is that the type should first be defined as a
+shell type, which is a placeholder type that has no properties except a name and an owner\&. This is done by issuing the command
+CREATE TYPE \fIname\fR, with no additional parameters\&. Then the C I/O functions can be defined referencing the shell type\&. Finally,
+\fBCREATE TYPE\fR
+with a full definition replaces the shell entry with a complete, valid type definition, after which the new type can be used normally\&.
+.PP
+The optional
+\fItype_modifier_input_function\fR
+and
+\fItype_modifier_output_function\fR
+are needed if the type supports modifiers, that is optional constraints attached to a type declaration, such as
+char(5)
+or
+numeric(30,2)\&.
+PostgreSQL
+allows user\-defined types to take one or more simple constants or identifiers as modifiers\&. However, this information must be capable of being packed into a single non\-negative integer value for storage in the system catalogs\&. The
+\fItype_modifier_input_function\fR
+is passed the declared modifier(s) in the form of a
+cstring
+array\&. It must check the values for validity (throwing an error if they are wrong), and if they are correct, return a single non\-negative
+integer
+value that will be stored as the column
+\(lqtypmod\(rq\&. Type modifiers will be rejected if the type does not have a
+\fItype_modifier_input_function\fR\&. The
+\fItype_modifier_output_function\fR
+converts the internal integer typmod value back to the correct form for user display\&. It must return a
+cstring
+value that is the exact string to append to the type name; for example
+numeric\*(Aqs function might return
+(30,2)\&. It is allowed to omit the
+\fItype_modifier_output_function\fR, in which case the default display format is just the stored typmod integer value enclosed in parentheses\&.
+.PP
+The optional
+\fIanalyze_function\fR
+performs type\-specific statistics collection for columns of the data type\&. By default,
+\fBANALYZE\fR
+will attempt to gather statistics using the type\*(Aqs
+\(lqequals\(rq
+and
+\(lqless\-than\(rq
+operators, if there is a default b\-tree operator class for the type\&. For non\-scalar types this behavior is likely to be unsuitable, so it can be overridden by specifying a custom analysis function\&. The analysis function must be declared to take a single argument of type
+internal, and return a
+boolean
+result\&. The detailed API for analysis functions appears in
+src/include/commands/vacuum\&.h\&.
+.PP
+The optional
+\fIsubscript_function\fR
+allows the data type to be subscripted in SQL commands\&. Specifying this function does not cause the type to be considered a
+\(lqtrue\(rq
+array type; for example, it will not be a candidate for the result type of
+ARRAY[]
+constructs\&. But if subscripting a value of the type is a natural notation for extracting data from it, then a
+\fIsubscript_function\fR
+can be written to define what that means\&. The subscript function must be declared to take a single argument of type
+internal, and return an
+internal
+result, which is a pointer to a struct of methods (functions) that implement subscripting\&. The detailed API for subscript functions appears in
+src/include/nodes/subscripting\&.h\&. It may also be useful to read the array implementation in
+src/backend/utils/adt/arraysubs\&.c, or the simpler code in
+contrib/hstore/hstore_subs\&.c\&. Additional information appears in
+Array Types
+below\&.
+.PP
+While the details of the new type\*(Aqs internal representation are only known to the I/O functions and other functions you create to work with the type, there are several properties of the internal representation that must be declared to
+PostgreSQL\&. Foremost of these is
+\fIinternallength\fR\&. Base data types can be fixed\-length, in which case
+\fIinternallength\fR
+is a positive integer, or variable\-length, indicated by setting
+\fIinternallength\fR
+to
+VARIABLE\&. (Internally, this is represented by setting
+typlen
+to \-1\&.) The internal representation of all variable\-length types must start with a 4\-byte integer giving the total length of this value of the type\&. (Note that the length field is often encoded, as described in
+Section\ \&73.2; it\*(Aqs unwise to access it directly\&.)
+.PP
+The optional flag
+PASSEDBYVALUE
+indicates that values of this data type are passed by value, rather than by reference\&. Types passed by value must be fixed\-length, and their internal representation cannot be larger than the size of the
+Datum
+type (4 bytes on some machines, 8 bytes on others)\&.
+.PP
+The
+\fIalignment\fR
+parameter specifies the storage alignment required for the data type\&. The allowed values equate to alignment on 1, 2, 4, or 8 byte boundaries\&. Note that variable\-length types must have an alignment of at least 4, since they necessarily contain an
+int4
+as their first component\&.
+.PP
+The
+\fIstorage\fR
+parameter allows selection of storage strategies for variable\-length data types\&. (Only
+plain
+is allowed for fixed\-length types\&.)
+plain
+specifies that data of the type will always be stored in\-line and not compressed\&.
+extended
+specifies that the system will first try to compress a long data value, and will move the value out of the main table row if it\*(Aqs still too long\&.
+external
+allows the value to be moved out of the main table, but the system will not try to compress it\&.
+main
+allows compression, but discourages moving the value out of the main table\&. (Data items with this storage strategy might still be moved out of the main table if there is no other way to make a row fit, but they will be kept in the main table preferentially over
+extended
+and
+external
+items\&.)
+.PP
+All
+\fIstorage\fR
+values other than
+plain
+imply that the functions of the data type can handle values that have been
+toasted, as described in
+Section\ \&73.2
+and
+Section\ \&38.13.1\&. The specific other value given merely determines the default TOAST storage strategy for columns of a toastable data type; users can pick other strategies for individual columns using
+ALTER TABLE SET STORAGE\&.
+.PP
+The
+\fIlike_type\fR
+parameter provides an alternative method for specifying the basic representation properties of a data type: copy them from some existing type\&. The values of
+\fIinternallength\fR,
+\fIpassedbyvalue\fR,
+\fIalignment\fR, and
+\fIstorage\fR
+are copied from the named type\&. (It is possible, though usually undesirable, to override some of these values by specifying them along with the
+LIKE
+clause\&.) Specifying representation this way is especially useful when the low\-level implementation of the new type
+\(lqpiggybacks\(rq
+on an existing type in some fashion\&.
+.PP
+The
+\fIcategory\fR
+and
+\fIpreferred\fR
+parameters can be used to help control which implicit cast will be applied in ambiguous situations\&. Each data type belongs to a category named by a single ASCII character, and each type is either
+\(lqpreferred\(rq
+or not within its category\&. The parser will prefer casting to preferred types (but only from other types within the same category) when this rule is helpful in resolving overloaded functions or operators\&. For more details see
+Chapter\ \&10\&. For types that have no implicit casts to or from any other types, it is sufficient to leave these settings at the defaults\&. However, for a group of related types that have implicit casts, it is often helpful to mark them all as belonging to a category and select one or two of the
+\(lqmost general\(rq
+types as being preferred within the category\&. The
+\fIcategory\fR
+parameter is especially useful when adding a user\-defined type to an existing built\-in category, such as the numeric or string types\&. However, it is also possible to create new entirely\-user\-defined type categories\&. Select any ASCII character other than an upper\-case letter to name such a category\&.
+.PP
+A default value can be specified, in case a user wants columns of the data type to default to something other than the null value\&. Specify the default with the
+DEFAULT
+key word\&. (Such a default can be overridden by an explicit
+DEFAULT
+clause attached to a particular column\&.)
+.PP
+To indicate that a type is a fixed\-length array type, specify the type of the array elements using the
+ELEMENT
+key word\&. For example, to define an array of 4\-byte integers (int4), specify
+ELEMENT = int4\&. For more details, see
+Array Types
+below\&.
+.PP
+To indicate the delimiter to be used between values in the external representation of arrays of this type,
+\fIdelimiter\fR
+can be set to a specific character\&. The default delimiter is the comma (,)\&. Note that the delimiter is associated with the array element type, not the array type itself\&.
+.PP
+If the optional Boolean parameter
+\fIcollatable\fR
+is true, column definitions and expressions of the type may carry collation information through use of the
+COLLATE
+clause\&. It is up to the implementations of the functions operating on the type to actually make use of the collation information; this does not happen automatically merely by marking the type collatable\&.
+.SS "Array Types"
+.PP
+Whenever a user\-defined type is created,
+PostgreSQL
+automatically creates an associated array type, whose name consists of the element type\*(Aqs name prepended with an underscore, and truncated if necessary to keep it less than
+NAMEDATALEN
+bytes long\&. (If the name so generated collides with an existing type name, the process is repeated until a non\-colliding name is found\&.) This implicitly\-created array type is variable length and uses the built\-in input and output functions
+array_in
+and
+array_out\&. Furthermore, this type is what the system uses for constructs such as
+ARRAY[]
+over the user\-defined type\&. The array type tracks any changes in its element type\*(Aqs owner or schema, and is dropped if the element type is\&.
+.PP
+You might reasonably ask why there is an
+\fBELEMENT\fR
+option, if the system makes the correct array type automatically\&. The main case where it\*(Aqs useful to use
+\fBELEMENT\fR
+is when you are making a fixed\-length type that happens to be internally an array of a number of identical things, and you want to allow these things to be accessed directly by subscripting, in addition to whatever operations you plan to provide for the type as a whole\&. For example, type
+point
+is represented as just two floating\-point numbers, which can be accessed using
+point[0]
+and
+point[1]\&. Note that this facility only works for fixed\-length types whose internal form is exactly a sequence of identical fixed\-length fields\&. For historical reasons (i\&.e\&., this is clearly wrong but it\*(Aqs far too late to change it), subscripting of fixed\-length array types starts from zero, rather than from one as for variable\-length arrays\&.
+.PP
+Specifying the
+\fBSUBSCRIPT\fR
+option allows a data type to be subscripted, even though the system does not otherwise regard it as an array type\&. The behavior just described for fixed\-length arrays is actually implemented by the
+\fBSUBSCRIPT\fR
+handler function
+\fBraw_array_subscript_handler\fR, which is used automatically if you specify
+\fBELEMENT\fR
+for a fixed\-length type without also writing
+\fBSUBSCRIPT\fR\&.
+.PP
+When specifying a custom
+\fBSUBSCRIPT\fR
+function, it is not necessary to specify
+\fBELEMENT\fR
+unless the
+\fBSUBSCRIPT\fR
+handler function needs to consult
+typelem
+to find out what to return\&. Be aware that specifying
+\fBELEMENT\fR
+causes the system to assume that the new type contains, or is somehow physically dependent on, the element type; thus for example changing properties of the element type won\*(Aqt be allowed if there are any columns of the dependent type\&.

+.SH "NOTES"
+.PP
+Because there are no restrictions on use of a data type once it\*(Aqs been created, creating a base type or range type is tantamount to granting public execute permission on the functions mentioned in the type definition\&. This is usually not an issue for the sorts of functions that are useful in a type definition\&. But you might want to think twice before designing a type in a way that would require
+\(lqsecret\(rq
+information to be used while converting it to or from external form\&.
+.PP
+Before
+PostgreSQL
+version 8\&.3, the name of a generated array type was always exactly the element type\*(Aqs name with one underscore character (_) prepended\&. (Type names were therefore restricted in length to one fewer character than other names\&.) While this is still usually the case, the array type name may vary from this in case of maximum\-length names or collisions with user type names that begin with underscore\&. Writing code that depends on this convention is therefore deprecated\&. Instead, use
+pg_type\&.typarray
+to locate the array type associated with a given type\&.
+.PP
+It may be advisable to avoid using type and table names that begin with underscore\&. While the server will change generated array type names to avoid collisions with user\-given names, there is still risk of confusion, particularly with old client software that may assume that type names beginning with underscores always represent arrays\&.
+.PP
+Before
+PostgreSQL
+version 8\&.2, the shell\-type creation syntax
+CREATE TYPE \fIname\fR
+did not exist\&. The way to create a new base type was to create its input function first\&. In this approach,
+PostgreSQL
+will first see the name of the new data type as the return type of the input function\&. The shell type is implicitly created in this situation, and then it can be referenced in the definitions of the remaining I/O functions\&. This approach still works, but is deprecated and might be disallowed in some future release\&. Also, to avoid accidentally cluttering the catalogs with shell types as a result of simple typos in function definitions, a shell type will only be made this way when the input function is written in C\&.

+.PP
+\fBCREATE OR REPLACE VIEW\fR
+is similar, but if a view of the same name already exists, it is replaced\&.

+.PP
+If a schema name is given (for example,

Temporary views exist in a special schema, so a schema name cannot be given when creating a temporary view\&.

+This option controls the behavior of automatically updatable views\&. When this option is specified,

+Note that the
+CHECK OPTION
+is only supported on views that are automatically updatable, and do not have
+INSTEAD OF
+triggers or
+INSTEAD
+rules\&. If an automatically updatable view is defined on top of a base view that has
+INSTEAD OF
+triggers, then the
+LOCAL CHECK OPTION
+may be used to check the conditions on the automatically updatable view, but the conditions on the base view with
+INSTEAD OF
+triggers will not be checked (a cascaded check option will not cascade down to a trigger\-updatable view, and any check options defined directly on a trigger\-updatable view will be ignored)\&. If the view or any of its base relations has an
+INSTEAD
+rule that causes the
+\fBINSERT\fR
+or
+\fBUPDATE\fR
+command to be rewritten, then all check options will be ignored in the rewritten query, including any checks from automatically updatable views defined on top of the relation with the
+INSTEAD
+rule\&.
+.RE
+.SH "NOTES"
+.PP
+Use the
+\fBDROP VIEW\fR
+statement to drop views\&.
+.PP
+Be careful that the names and types of the view\*(Aqs columns will be assigned the way you want\&. For example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE VIEW vista AS SELECT \*(AqHello World\*(Aq;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+is bad form because the column name defaults to
+?column?; also, the column data type defaults to
+text, which might not be what you wanted\&. Better style for a string literal in a view\*(Aqs result is something like:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE VIEW vista AS SELECT text \*(AqHello World\*(Aq AS hello;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+By default, access to the underlying base relations referenced in the view is determined by the permissions of the view owner\&. In some cases, this can be used to provide secure but restricted access to the underlying tables\&. However, not all views are secure against tampering; see
+Section\ \&41.5
+for details\&.
+.PP
+If the view has the
+security_invoker
+property set to
+true, access to the underlying base relations is determined by the permissions of the user executing the query, rather than the view owner\&. Thus, the user of a security invoker view must have the relevant permissions on the view and its underlying base relations\&.
+.PP
+If any of the underlying base relations is a security invoker view, it will be treated as if it had been accessed directly from the original query\&. Thus, a security invoker view will always check its underlying base relations using the permissions of the current user, even if it is accessed from a view without the
+security_invoker
+property\&.
+.PP
+If any of the underlying base relations has
+row\-level security
+enabled, then by default, the row\-level security policies of the view owner are applied, and access to any additional relations referred to by those policies is determined by the permissions of the view owner\&. However, if the view has
+security_invoker
+set to
+true, then the policies and permissions of the invoking user are used instead, as if the base relations had been referenced directly from the query using the view\&.
+.PP
+Functions called in the view are treated the same as if they had been called directly from the query using the view\&. Therefore, the user of a view must have permissions to call all functions used by the view\&. Functions in the view are executed with the privileges of the user executing the query or the function owner, depending on whether the functions are defined as
+SECURITY INVOKER
+or
+SECURITY DEFINER\&. Thus, for example, calling
+CURRENT_USER
+directly in a view will always return the invoking user, not the view owner\&. This is not affected by the view\*(Aqs
+security_invoker
+setting, and so a view with
+security_invoker
+set to
+false
+is
+\fInot\fR
+equivalent to a
+SECURITY DEFINER
+function and those concepts should not be confused\&.
+.PP
+The user creating or replacing a view must have
+USAGE
+privileges on any schemas referred to in the view query, in order to look up the referenced objects in those schemas\&. Note, however, that this lookup only happens when the view is created or replaced\&. Therefore, the user of the view only requires the
+USAGE
+privilege on the schema containing the view, not on the schemas referred to in the view query, even for a security invoker view\&.
+.PP
+When
+\fBCREATE OR REPLACE VIEW\fR
+is used on an existing view, only the view\*(Aqs defining SELECT rule, plus any
+WITH ( \&.\&.\&. )
+parameters and its
+CHECK OPTION
+are changed\&. Other view properties, including ownership, permissions, and non\-SELECT rules, remain unchanged\&. You must own the view to replace it (this includes being a member of the owning role)\&.
+.SS "Updatable Views"
+.PP
+Simple views are automatically updatable: the system will allow
+\fBINSERT\fR,
+\fBUPDATE\fR
+and
+\fBDELETE\fR
+statements to be used on the view in the same way as on a regular table\&. A view is automatically updatable if it satisfies all of the following conditions:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The view must have exactly one entry in its
+FROM
+list, which must be a table or another updatable view\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The view definition must not contain
+WITH,
+DISTINCT,
+GROUP BY,
+HAVING,
+LIMIT, or
+OFFSET
+clauses at the top level\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The view definition must not contain set operations (UNION,
+INTERSECT
+or
+EXCEPT) at the top level\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+The view\*(Aqs select list must not contain any aggregates, window functions or set\-returning functions\&.
+.RE
+.PP
+An automatically updatable view may contain a mix of updatable and non\-updatable columns\&. A column is updatable if it is a simple reference to an updatable column of the underlying base relation; otherwise the column is read\-only, and an error will be raised if an
+\fBINSERT\fR
+or
+\fBUPDATE\fR
+statement attempts to assign a value to it\&.
+.PP
+If the view is automatically updatable the system will convert any
+\fBINSERT\fR,
+\fBUPDATE\fR
+or
+\fBDELETE\fR
+statement on the view into the corresponding statement on the underlying base relation\&.
+\fBINSERT\fR
+statements that have an
+ON CONFLICT UPDATE
+clause are fully supported\&.
+.PP
+If an automatically updatable view contains a
+WHERE
+condition, the condition restricts which rows of the base relation are available to be modified by
+\fBUPDATE\fR
+and
+\fBDELETE\fR
+statements on the view\&. However, an
+\fBUPDATE\fR
+is allowed to change a row so that it no longer satisfies the
+WHERE
+condition, and thus is no longer visible through the view\&. Similarly, an
+\fBINSERT\fR
+command can potentially insert base\-relation rows that do not satisfy the
+WHERE
+condition and thus are not visible through the view (ON CONFLICT UPDATE
+may similarly affect an existing row not visible through the view)\&. The
+CHECK OPTION
+may be used to prevent
+\fBINSERT\fR
+and
+\fBUPDATE\fR
+commands from creating such rows that are not visible through the view\&.
+.PP
+If an automatically updatable view is marked with the
+security_barrier
+property then all the view\*(Aqs
+WHERE
+conditions (and any conditions using operators which are marked as
+LEAKPROOF) will always be evaluated before any conditions that a user of the view has added\&. See
+Section\ \&41.5
+for full details\&. Note that, due to this, rows which are not ultimately returned (because they do not pass the user\*(Aqs
+WHERE
+conditions) may still end up being locked\&.
+\fBEXPLAIN\fR
+can be used to see which conditions are applied at the relation level (and therefore do not lock rows) and which are not\&.
+.PP
+A more complex view that does not satisfy all these conditions is read\-only by default: the system will not allow an insert, update, or delete on the view\&. You can get the effect of an updatable view by creating
+INSTEAD OF
+triggers on the view, which must convert attempted inserts, etc\&. on the view into appropriate actions on other tables\&. For more information see
+CREATE TRIGGER (\fBCREATE_TRIGGER\fR(7))\&. Another possibility is to create rules (see
+CREATE RULE (\fBCREATE_RULE\fR(7))), but in practice triggers are easier to understand and use correctly\&.
+.PP
+Note that the user performing the insert, update or delete on the view must have the corresponding insert, update or delete privilege on the view\&. In addition, by default, the view\*(Aqs owner must have the relevant privileges on the underlying base relations, whereas the user performing the update does not need any permissions on the underlying base relations (see
+Section\ \&41.5)\&. However, if the view has
+security_invoker
+set to
+true, the user performing the update, rather than the view owner, must have the relevant privileges on the underlying base relations\&.

As an example, if a query returns a value of one from an integer column, you would get a string of
+1
+with a default cursor, whereas with a binary cursor you would get a 4\-byte field containing the internal representation of the value (in big\-endian byte order)\&.

+When the client application uses the
+\(lqextended query\(rq

The concept of a binary cursor as such is thus obsolete when using extended query protocol \(em any cursor can be treated as either text or binary\&.
+.sp .5v
+.RE
+.PP
+Unless
+WITH HOLD
+is specified, the cursor created by this command can only be used within the current transaction\&. Thus,
+\fBDECLARE\fR
+without
+WITH HOLD
+is useless outside a transaction block: the cursor would survive only to the completion of the statement\&. Therefore
+PostgreSQL
+reports an error if such a command is used outside a transaction block\&. Use

+\fBROLLBACK\fR) to define a transaction block\&.
+.PP
+If
+WITH HOLD
+is specified and the transaction that created the cursor successfully commits, the cursor can continue to be accessed by subsequent transactions in the same session\&. (But if the creating transaction is aborted, the cursor is removed\&.) A cursor created with

+is closed when an explicit
+\fBCLOSE\fR
+command is issued on it, or the session ends\&. In the current implementation, the rows represented by a held cursor are copied into a temporary file or memory area so that they remain available for subsequent transactions\&.

+The

+PostgreSQL
+will allow backward fetches without
+SCROLL, if the cursor\*(Aqs query plan is simple enough that no extra overhead is needed to support it\&. However, application developers are advised not to rely on using backward fetches from a cursor that has not been created with
+SCROLL\&. If
+NO SCROLL
+is specified, then backward fetches are disallowed in any case\&.

+Scrollable cursors may give unexpected results if they invoke any volatile functions (see
+Section\ \&38.7)\&. When a previously fetched row is re\-fetched, the functions might be re\-executed, perhaps leading to results different from the first time\&. It\*(Aqs best to specify
+NO SCROLL
+for a query involving volatile functions\&. If that is not practical, one workaround is to declare the cursor
+SCROLL WITH HOLD
+and commit the transaction before reading any rows from it\&. This will force the entire output of the cursor to be materialized in temporary storage, so that volatile functions are executed exactly once for each row\&.

+It is generally recommended to use

+or
+\fBDELETE \&.\&.\&. WHERE CURRENT OF\fR\&. Using
+FOR UPDATE
+prevents other sessions from changing the rows between the time they are fetched and the time they are updated\&. Without
+FOR UPDATE, a subsequent
+WHERE CURRENT OF
+command will have no effect if the row was changed since the cursor was created\&.
+.PP
+Another reason to use
+FOR UPDATE
+is that without it, a subsequent
+WHERE CURRENT OF
+might fail if the cursor query does not meet the SQL standard\*(Aqs rules for being
+\(lqsimply updatable\(rq
+(in particular, the cursor must reference just one table and not use grouping or
+ORDER BY)\&. Cursors that are not simply updatable might work, or might not, depending on plan choice details; so in the worst case, an application might work in testing and then fail in production\&. If
+FOR UPDATE
+is specified, the cursor is guaranteed to be updatable\&.
+.PP
+The main reason not to use
+FOR UPDATE
+with
+WHERE CURRENT OF
+is if you need the cursor to be scrollable, or to be isolated from concurrent updates (that is, continue to show the old data)\&. If this is a requirement, pay close heed to the caveats shown above\&.
+.sp .5v
+.RE
+.PP
+The SQL standard only makes provisions for cursors in embedded
+SQL\&. The
+PostgreSQL
+server does not implement an
+\fBOPEN\fR
+statement for cursors; a cursor is considered to be open when it is declared\&. However,

+What is essentially happening here is a join between

+\fBDROP PROCEDURE\fR
+removes the definition of one or more existing procedures\&. To execute this command the user must be the owner of the procedure(s)\&. The argument types to the procedure(s) usually must be specified, since several different procedures can exist with the same name and different argument lists\&.

+.RE
+.SH "NOTES"
+.PP
+If there is only one procedure of the given name, the argument list can be omitted\&. Omit the parentheses too in this case\&.
+.PP
+In
+PostgreSQL, it\*(Aqs sufficient to list the input (including
+INOUT) arguments, because no two routines of the same name are allowed to share the same input\-argument list\&. Moreover, the
+\fBDROP\fR
+command will not actually check that you wrote the types of
+OUT
+arguments correctly; so any arguments that are explicitly marked
+OUT
+are just noise\&. But writing them is recommendable for consistency with the corresponding
+\fBCREATE\fR
+command\&.
+.PP
+For compatibility with the SQL standard, it is also allowed to write all the argument data types (including those of
+OUT
+arguments) without any
+\fIargmode\fR
+markers\&. When this is done, the types of the procedure\*(Aqs
+OUT
+argument(s)
+\fIwill\fR
+be verified against the command\&. This provision creates an ambiguity, in that when the argument list contains no
+\fIargmode\fR
+markers, it\*(Aqs unclear which rule is intended\&. The
+\fBDROP\fR
+command will attempt the lookup both ways, and will throw an error if two different procedures are found\&. To avoid the risk of such ambiguity, it\*(Aqs recommendable to write
+IN
+markers explicitly rather than letting them be defaulted, thus forcing the traditional
+PostgreSQL
+interpretation to be used\&.
+.PP
+The lookup rules just explained are also used by other commands that act on existing procedures, such as
+\fBALTER PROCEDURE\fR
+and
+\fBCOMMENT ON PROCEDURE\fR\&.
+.SH "EXAMPLES"

+do_db_maintenance, this command is sufficient to drop it:

+.SH "DESCRIPTION"
+.PP
+This command displays the execution plan that the
+PostgreSQL
+planner generates for the supplied statement\&. The execution plan shows how the table(s) referenced by the statement will be scanned \(em by plain sequential scan, index scan, etc\&. \(em and if multiple tables are referenced, what join algorithms will be used to bring together the required rows from each input table\&.
+.PP
+The most critical part of the display is the estimated statement execution cost, which is the planner\*(Aqs guess at how long it will take to run the statement (measured in cost units that are arbitrary, but conventionally mean disk page fetches)\&. Actually two numbers are shown: the start\-up cost before the first row can be returned, and the total cost to return all the rows\&. For most queries the total cost is what matters, but in contexts such as a subquery in
+EXISTS, the planner will choose the smallest start\-up cost instead of the smallest total cost (since the executor will stop after getting one row, anyway)\&. Also, if you limit the number of rows to return with a
+LIMIT
+clause, the planner makes an appropriate interpolation between the endpoint costs to estimate which plan is really the cheapest\&.
+.PP
+The
+ANALYZE
+option causes the statement to be actually executed, not only planned\&. Then actual run time statistics are added to the display, including the total elapsed time expended within each plan node (in milliseconds) and the total number of rows it actually returned\&. This is useful for seeing whether the planner\*(Aqs estimates are close to reality\&.

+Keep in mind that the statement is actually executed when the

+\fBEXPLAIN\fR
+will discard any output that a

+.SH "PARAMETERS"
+.PP
+ANALYZE
+.RS 4
+Carry out the command and show actual run times and other statistics\&. This parameter defaults to
+FALSE\&.
+.RE
+.PP
+VERBOSE
+.RS 4
+Display additional information regarding the plan\&. Specifically, include the output column list for each node in the plan tree, schema\-qualify table and function names, always label variables in expressions with their range table alias, and always print the name of each trigger for which statistics are displayed\&. The query identifier will also be displayed if one has been computed, see
+compute_query_id
+for more details\&. This parameter defaults to
+FALSE\&.
+.RE
+.PP
+COSTS
+.RS 4
+Include information on the estimated startup and total cost of each plan node, as well as the estimated number of rows and the estimated width of each row\&. This parameter defaults to
+TRUE\&.
+.RE
+.PP
+SETTINGS
+.RS 4
+Include information on configuration parameters\&. Specifically, include options affecting query planning with value different from the built\-in default value\&. This parameter defaults to
+FALSE\&.
+.RE
+.PP
+BUFFERS
+.RS 4
+Include information on buffer usage\&. Specifically, include the number of shared blocks hit, read, dirtied, and written, the number of local blocks hit, read, dirtied, and written, the number of temp blocks read and written, and the time spent reading and writing data file blocks and temporary file blocks (in milliseconds) if
+track_io_timing
+is enabled\&. A
+\fIhit\fR
+means that a read was avoided because the block was found already in cache when needed\&. Shared blocks contain data from regular tables and indexes; local blocks contain data from temporary tables and indexes; while temporary blocks contain short\-term working data used in sorts, hashes, Materialize plan nodes, and similar cases\&. The number of blocks
+\fIdirtied\fR
+indicates the number of previously unmodified blocks that were changed by this query; while the number of blocks
+\fIwritten\fR
+indicates the number of previously\-dirtied blocks evicted from cache by this backend during query processing\&. The number of blocks shown for an upper\-level node includes those used by all its child nodes\&. In text format, only non\-zero values are printed\&. It defaults to
+FALSE\&.
+.RE
+.PP
+WAL
+.RS 4
+Include information on WAL record generation\&. Specifically, include the number of records, number of full page images (fpi) and the amount of WAL generated in bytes\&. In text format, only non\-zero values are printed\&. This parameter may only be used when
+ANALYZE
+is also enabled\&. It defaults to
+FALSE\&.
+.RE
+.PP
+TIMING
+.RS 4
+Include actual startup time and time spent in each node in the output\&. The overhead of repeatedly reading the system clock can slow down the query significantly on some systems, so it may be useful to set this parameter to
+FALSE
+when only actual row counts, and not exact times, are needed\&. Run time of the entire statement is always measured, even when node\-level timing is turned off with this option\&. This parameter may only be used when
+ANALYZE
+is also enabled\&. It defaults to
+TRUE\&.
+.RE
+.PP
+SUMMARY
+.RS 4
+Include summary information (e\&.g\&., totaled timing information) after the query plan\&. Summary information is included by default when
+ANALYZE
+is used but otherwise is not included by default, but can be enabled using this option\&. Planning time in
+\fBEXPLAIN EXECUTE\fR
+includes the time required to fetch the plan from the cache and the time required for re\-planning, if necessary\&.
+.RE
+.PP
+FORMAT
+.RS 4
+Specify the output format, which can be TEXT, XML, JSON, or YAML\&. Non\-text output contains the same information as the text output format, but is easier for programs to parse\&. This parameter defaults to
+TEXT\&.
+.RE
+.PP
+\fIboolean\fR
+.RS 4
+Specifies whether the selected option should be turned on or off\&. You can write
+TRUE,
+ON, or
+1
+to enable the option, and
+FALSE,
+OFF, or
+0
+to disable it\&. The
+\fIboolean\fR
+value can also be omitted, in which case

+.SH "OUTPUTS"
+.PP
+The command\*(Aqs result is a textual description of the plan selected for the
+\fIstatement\fR, optionally annotated with execution statistics\&.
+Section\ \&14.1
+describes the information provided\&.
+.SH "NOTES"
+.PP
+In order to allow the
+PostgreSQL
+query planner to make reasonably informed decisions when optimizing queries, the
+pg_statistic
+data should be up\-to\-date for all tables used in the query\&. Normally the
+autovacuum daemon
+will take care of that automatically\&. But if a table has recently had substantial changes in its contents, you might need to do a manual
+\fBANALYZE\fR
+rather than wait for autovacuum to catch up with the changes\&.
+.PP
+In order to measure the run\-time cost of each node in the execution plan, the current implementation of
+\fBEXPLAIN ANALYZE\fR
+adds profiling overhead to query execution\&. As a result, running
+\fBEXPLAIN ANALYZE\fR
+on a query can sometimes take significantly longer than executing the query normally\&. The amount of overhead depends on the nature of the query, as well as the platform being used\&. The worst case occurs for plan nodes that in themselves require very little time per execution, and on machines that have relatively slow operating system calls for obtaining the time of day\&.

+.PP
+ABSOLUTE
+fetches are not any faster than navigating to the desired row with a relative move: the underlying implementation must traverse all the intermediate rows anyway\&. Negative absolute fetches are even worse: the query must be read to the end to find the last row, and then traversed backward from there\&. However, rewinding to the start of the query (as with

+.SH "DESCRIPTION"
+.PP
+The
+\fBGRANT\fR
+command has two basic variants: one that grants privileges on a database object (table, column, view, foreign table, sequence, database, foreign\-data wrapper, foreign server, function, procedure, procedural language, large object, configuration parameter, schema, tablespace, or type), and one that grants membership in a role\&. These variants are similar in many ways, but they are different enough to be described separately\&.
+.SS "GRANT on Database Objects"
+.PP
+This variant of the
+\fBGRANT\fR
+command gives specific privileges on a database object to one or more roles\&. These privileges are added to those already granted, if any\&.
+.PP
+The key word
+PUBLIC
+indicates that the privileges are to be granted to all roles, including those that might be created later\&.
+PUBLIC
+can be thought of as an implicitly defined group that always includes all roles\&. Any particular role will have the sum of privileges granted directly to it, privileges granted to any role it is presently a member of, and privileges granted to
+PUBLIC\&.
+.PP
+If
+WITH GRANT OPTION
+is specified, the recipient of the privilege can in turn grant it to others\&. Without a grant option, the recipient cannot do that\&. Grant options cannot be granted to
+PUBLIC\&.
+.PP
+If
+GRANTED BY
+is specified, the specified grantor must be the current user\&. This clause is currently present in this form only for SQL compatibility\&.
+.PP
+There is no need to grant privileges to the owner of an object (usually the user that created it), as the owner has all privileges by default\&. (The owner could, however, choose to revoke some of their own privileges for safety\&.)
+.PP
+The right to drop an object, or to alter its definition in any way, is not treated as a grantable privilege; it is inherent in the owner, and cannot be granted or revoked\&. (However, a similar effect can be obtained by granting or revoking membership in the role that owns the object; see below\&.) The owner implicitly has all grant options for the object, too\&.
+.PP
+The possible privileges are:
+.PP
+SELECT
+.br
+INSERT
+.br
+UPDATE
+.br
+DELETE
+.br
+TRUNCATE
+.br
+REFERENCES
+.br
+TRIGGER
+.br
+CREATE
+.br
+CONNECT
+.br
+TEMPORARY
+.br
+EXECUTE
+.br
+USAGE
+.br
+SET
+.br
+ALTER SYSTEM
+.RS 4
+Specific types of privileges, as defined in
+Section\ \&5.7\&.
+.RE
+.PP
+TEMP
+.RS 4
+Alternative spelling for
+TEMPORARY\&.
+.RE
+.PP
+ALL PRIVILEGES
+.RS 4
+Grant all of the privileges available for the object\*(Aqs type\&. The
+PRIVILEGES
+key word is optional in
+PostgreSQL, though it is required by strict SQL\&.
+.RE
+.PP
+The
+FUNCTION
+syntax works for plain functions, aggregate functions, and window functions, but not for procedures; use
+PROCEDURE
+for those\&. Alternatively, use
+ROUTINE
+to refer to a function, aggregate function, window function, or procedure regardless of its precise type\&.
+.PP
+There is also an option to grant privileges on all objects of the same type within one or more schemas\&. This functionality is currently supported only for tables, sequences, functions, and procedures\&.
+ALL TABLES
+also affects views and foreign tables, just like the specific\-object
+\fBGRANT\fR
+command\&.
+ALL FUNCTIONS
+also affects aggregate and window functions, but not procedures, again just like the specific\-object
+\fBGRANT\fR
+command\&. Use
+ALL ROUTINES
+to include procedures\&.
+.SS "GRANT on Roles"
+.PP
+This variant of the
+\fBGRANT\fR
+command grants membership in a role to one or more other roles\&. Membership in a role is significant because it conveys the privileges granted to a role to each of its members\&.
+.PP
+If
+WITH ADMIN OPTION
+is specified, the member can in turn grant membership in the role to others, and revoke membership in the role as well\&. Without the admin option, ordinary users cannot do that\&. A role is not considered to hold
+WITH ADMIN OPTION
+on itself\&. Database superusers can grant or revoke membership in any role to anyone\&. Roles having
+CREATEROLE
+privilege can grant or revoke membership in any role that is not a superuser\&.
+.PP
+If
+GRANTED BY
+is specified, the grant is recorded as having been done by the specified role\&. Only database superusers may use this option, except when it names the same role executing the command\&.
+.PP
+Unlike the case with privileges, membership in a role cannot be granted to
+PUBLIC\&. Note also that this form of the command does not allow the noise word
+GROUP
+in
+\fIrole_specification\fR\&.
+.SH "NOTES"
+.PP
+The
+\fBREVOKE\fR
+command is used to revoke access privileges\&.
+.PP
+Since
+PostgreSQL
+8\&.1, the concepts of users and groups have been unified into a single kind of entity called a role\&. It is therefore no longer necessary to use the keyword
+GROUP
+to identify whether a grantee is a user or a group\&.
+GROUP
+is still allowed in the command, but it is a noise word\&.
+.PP
+A user may perform
+\fBSELECT\fR,
+\fBINSERT\fR, etc\&. on a column if they hold that privilege for either the specific column or its whole table\&. Granting the privilege at the table level and then revoking it for one column will not do what one might wish: the table\-level grant is unaffected by a column\-level operation\&.
+.PP
+When a non\-owner of an object attempts to
+\fBGRANT\fR
+privileges on the object, the command will fail outright if the user has no privileges whatsoever on the object\&. As long as some privilege is available, the command will proceed, but it will grant only those privileges for which the user has grant options\&. The
+\fBGRANT ALL PRIVILEGES\fR
+forms will issue a warning message if no grant options are held, while the other forms will issue a warning if grant options for any of the privileges specifically named in the command are not held\&. (In principle these statements apply to the object owner as well, but since the owner is always treated as holding all grant options, the cases can never occur\&.)
+.PP
+It should be noted that database superusers can access all objects regardless of object privilege settings\&. This is comparable to the rights of
+root
+in a Unix system\&. As with
+root, it\*(Aqs unwise to operate as a superuser except when absolutely necessary\&.
+.PP
+If a superuser chooses to issue a
+\fBGRANT\fR
+or
+\fBREVOKE\fR
+command, the command is performed as though it were issued by the owner of the affected object\&. In particular, privileges granted via such a command will appear to have been granted by the object owner\&. (For role membership, the membership appears to have been granted by the containing role itself\&.)
+.PP
+\fBGRANT\fR
+and
+\fBREVOKE\fR
+can also be done by a role that is not the owner of the affected object, but is a member of the role that owns the object, or is a member of a role that holds privileges
+WITH GRANT OPTION
+on the object\&. In this case the privileges will be recorded as having been granted by the role that actually owns the object or holds the privileges
+WITH GRANT OPTION\&. For example, if table
+t1
+is owned by role
+g1, of which role
+u1
+is a member, then
+u1
+can grant privileges on
+t1
+to
+u2, but those privileges will appear to have been granted directly by
+g1\&. Any other member of role
+g1
+could revoke them later\&.
+.PP
+If the role executing
+\fBGRANT\fR
+holds the required privileges indirectly via more than one role membership path, it is unspecified which containing role will be recorded as having done the grant\&. In such cases it is best practice to use
+\fBSET ROLE\fR
+to become the specific role you want to do the
+\fBGRANT\fR
+as\&.
+.PP
+Granting permission on a table does not automatically extend permissions to any sequences used by the table, including sequences tied to
+SERIAL
+columns\&. Permissions on sequences must be set separately\&.
+.PP
+See
+Section\ \&5.7
+for more information about specific privilege types, as well as how to inspect objects\*(Aq privileges\&.
+.SH "EXAMPLES"
+.PP
+Grant insert privilege to all users on table
+films:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+GRANT INSERT ON films TO PUBLIC;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Grant all available privileges to user
+manuel
+on view
+kinds:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+GRANT ALL PRIVILEGES ON kinds TO manuel;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Note that while the above will indeed grant all privileges if executed by a superuser or the owner of
+kinds, when executed by someone else it will only grant those permissions for which the someone else has grant options\&.
+.PP
+Grant membership in role
+admins
+to user
+joe:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+GRANT admins TO joe;
+.fi
+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"
+.PP
+According to the SQL standard, the
+PRIVILEGES
+key word in
+ALL PRIVILEGES
+is required\&. The SQL standard does not support setting the privileges on more than one object per command\&.
+.PP
+PostgreSQL
+allows an object owner to revoke their own ordinary privileges: for example, a table owner can make the table read\-only to themselves by revoking their own
+INSERT,
+UPDATE,
+DELETE, and
+TRUNCATE
+privileges\&. This is not possible according to the SQL standard\&. The reason is that
+PostgreSQL
+treats the owner\*(Aqs privileges as having been granted by the owner to themselves; therefore they can revoke them too\&. In the SQL standard, the owner\*(Aqs privileges are granted by an assumed entity
+\(lq_SYSTEM\(rq\&. Not being
+\(lq_SYSTEM\(rq, the owner cannot revoke these rights\&.
+.PP
+According to the SQL standard, grant options can be granted to
+PUBLIC; PostgreSQL only supports granting grant options to roles\&.
+.PP
+The SQL standard allows the
+GRANTED BY
+option to specify only
+CURRENT_USER
+or
+CURRENT_ROLE\&. The other variants are PostgreSQL extensions\&.
+.PP
+The SQL standard provides for a
+USAGE
+privilege on other kinds of objects: character sets, collations, translations\&.
+.PP
+In the SQL standard, sequences only have a
+USAGE
+privilege, which controls the use of the
+NEXT VALUE FOR
+expression, which is equivalent to the function
+\fBnextval\fR
+in PostgreSQL\&. The sequence privileges
+SELECT
+and
+UPDATE
+are PostgreSQL extensions\&. The application of the sequence
+USAGE
+privilege to the
+currval
+function is also a PostgreSQL extension (as is the function itself)\&.
+.PP
+Privileges on databases, tablespaces, schemas, languages, and configuration parameters are
+PostgreSQL
+extensions\&.

+.SH "DESCRIPTION"
+.PP
+\fBINSERT\fR
+inserts new rows into a table\&. One can insert one or more rows specified by value expressions, or zero or more rows resulting from a query\&.
+.PP
+The target column names can be listed in any order\&. If no list of column names is given at all, the default is all the columns of the table in their declared order; or the first
+\fIN\fR
+column names, if there are only
+\fIN\fR
+columns supplied by the
+VALUES
+clause or
+\fIquery\fR\&. The values supplied by the
+VALUES
+clause or
+\fIquery\fR
+are associated with the explicit or implicit column list left\-to\-right\&.
+.PP
+Each column not present in the explicit or implicit column list will be filled with a default value, either its declared default value or null if there is none\&.
+.PP
+If the expression for any column is not of the correct data type, automatic type conversion will be attempted\&.
+.PP
+\fBINSERT\fR
+into tables that lack unique indexes will not be blocked by concurrent activity\&. Tables with unique indexes might block if concurrent sessions perform actions that lock or modify rows matching the unique index values being inserted; the details are covered in
+Section\ \&64.5\&.
+ON CONFLICT
+can be used to specify an alternative action to raising a unique constraint or exclusion constraint violation error\&. (See
+ON CONFLICT Clause
+below\&.)
+.PP
+The optional
+RETURNING
+clause causes
+\fBINSERT\fR
+to compute and return value(s) based on each row actually inserted (or updated, if an
+ON CONFLICT DO UPDATE
+clause was used)\&. This is primarily useful for obtaining values that were supplied by defaults, such as a serial sequence number\&. However, any expression using the table\*(Aqs columns is allowed\&. The syntax of the
+RETURNING
+list is identical to that of the output list of
+\fBSELECT\fR\&. Only rows that were successfully inserted or updated will be returned\&. For example, if a row was locked but not updated because an
+ON CONFLICT DO UPDATE \&.\&.\&. WHERE
+clause
+\fIcondition\fR
+was not satisfied, the row will not be returned\&.
+.PP
+You must have
+INSERT
+privilege on a table in order to insert into it\&. If
+ON CONFLICT DO UPDATE
+is present,
+UPDATE
+privilege on the table is also required\&.
+.PP
+If a column list is specified, you only need
+INSERT
+privilege on the listed columns\&. Similarly, when
+ON CONFLICT DO UPDATE
+is specified, you only need
+UPDATE
+privilege on the column(s) that are listed to be updated\&. However,
+ON CONFLICT DO UPDATE
+also requires
+SELECT
+privilege on any column whose values are read in the
+ON CONFLICT DO UPDATE
+expressions or
+\fIcondition\fR\&.
+.PP
+Use of the
+RETURNING
+clause requires
+SELECT
+privilege on all columns mentioned in
+RETURNING\&. If you use the
+\fIquery\fR
+clause to insert rows from a query, you of course need to have
+SELECT
+privilege on any table or column used in the query\&.
+.SH "PARAMETERS"
+.SS "Inserting"
+.PP
+This section covers parameters that may be used when only inserting new rows\&. Parameters
+\fIexclusively\fR
+used with the
+ON CONFLICT
+clause are described separately\&.
+.PP
+\fIwith_query\fR
+.RS 4
+The
+WITH
+clause allows you to specify one or more subqueries that can be referenced by name in the
+\fBINSERT\fR
+query\&. See
+Section\ \&7.8
+and
+\fBSELECT\fR(7)
+for details\&.
+.sp
+It is possible for the
+\fIquery\fR
+(\fBSELECT\fR
+statement) to also contain a
+WITH
+clause\&. In such a case both sets of
+\fIwith_query\fR
+can be referenced within the
+\fIquery\fR, but the second one takes precedence since it is more closely nested\&.
+.RE
+.PP
+\fItable_name\fR
+.RS 4
+The name (optionally schema\-qualified) of an existing table\&.
+.RE
+.PP
+\fIalias\fR
+.RS 4
+A substitute name for
+\fItable_name\fR\&. When an alias is provided, it completely hides the actual name of the table\&. This is particularly useful when
+ON CONFLICT DO UPDATE
+targets a table named
+\fIexcluded\fR, since that will otherwise be taken as the name of the special table representing the row proposed for insertion\&.
+.RE
+.PP
+\fIcolumn_name\fR
+.RS 4
+The name of a column in the table named by
+\fItable_name\fR\&. The column name can be qualified with a subfield name or array subscript, if needed\&. (Inserting into only some fields of a composite column leaves the other fields null\&.) When referencing a column with
+ON CONFLICT DO UPDATE, do not include the table\*(Aqs name in the specification of a target column\&. For example,
+INSERT INTO table_name \&.\&.\&. ON CONFLICT DO UPDATE SET table_name\&.col = 1
+is invalid (this follows the general behavior for
+\fBUPDATE\fR)\&.
+.RE
+.PP
+OVERRIDING SYSTEM VALUE
+.RS 4
+If this clause is specified, then any values supplied for identity columns will override the default sequence\-generated values\&.
+.sp
+For an identity column defined as
+GENERATED ALWAYS, it is an error to insert an explicit value (other than
+DEFAULT) without specifying either
+OVERRIDING SYSTEM VALUE
+or
+OVERRIDING USER VALUE\&. (For an identity column defined as
+GENERATED BY DEFAULT,
+OVERRIDING SYSTEM VALUE
+is the normal behavior and specifying it does nothing, but
+PostgreSQL
+allows it as an extension\&.)
+.RE
+.PP
+OVERRIDING USER VALUE
+.RS 4
+If this clause is specified, then any values supplied for identity columns are ignored and the default sequence\-generated values are applied\&.
+.sp
+This clause is useful for example when copying values between tables\&. Writing
+INSERT INTO tbl2 OVERRIDING USER VALUE SELECT * FROM tbl1
+will copy from
+tbl1
+all columns that are not identity columns in
+tbl2
+while values for the identity columns in
+tbl2
+will be generated by the sequences associated with
+tbl2\&.
+.RE
+.PP
+DEFAULT VALUES
+.RS 4
+All columns will be filled with their default values, as if
+DEFAULT
+were explicitly specified for each column\&. (An
+OVERRIDING
+clause is not permitted in this form\&.)
+.RE
+.PP
+\fIexpression\fR
+.RS 4
+An expression or value to assign to the corresponding column\&.
+.RE
+.PP
+DEFAULT
+.RS 4
+The corresponding column will be filled with its default value\&. An identity column will be filled with a new value generated by the associated sequence\&. For a generated column, specifying this is permitted but merely specifies the normal behavior of computing the column from its generation expression\&.
+.RE
+.PP
+\fIquery\fR
+.RS 4
+A query (\fBSELECT\fR
+statement) that supplies the rows to be inserted\&. Refer to the
+\fBSELECT\fR(7)
+statement for a description of the syntax\&.
+.RE
+.PP
+\fIoutput_expression\fR
+.RS 4
+An expression to be computed and returned by the
+\fBINSERT\fR
+command after each row is inserted or updated\&. The expression can use any column names of the table named by
+\fItable_name\fR\&. Write
+*
+to return all columns of the inserted or updated row(s)\&.
+.RE
+.PP
+\fIoutput_name\fR
+.RS 4
+A name to use for a returned column\&.
+.RE
+.SS "ON CONFLICT Clause"
+.PP
+The optional
+ON CONFLICT
+clause specifies an alternative action to raising a unique violation or exclusion constraint violation error\&. For each individual row proposed for insertion, either the insertion proceeds, or, if an
+\fIarbiter\fR
+constraint or index specified by
+\fIconflict_target\fR
+is violated, the alternative
+\fIconflict_action\fR
+is taken\&.
+ON CONFLICT DO NOTHING
+simply avoids inserting a row as its alternative action\&.
+ON CONFLICT DO UPDATE
+updates the existing row that conflicts with the row proposed for insertion as its alternative action\&.
+.PP
+\fIconflict_target\fR
+can perform
+\fIunique index inference\fR\&. When performing inference, it consists of one or more
+\fIindex_column_name\fR
+columns and/or
+\fIindex_expression\fR
+expressions, and an optional
+\fIindex_predicate\fR\&. All
+\fItable_name\fR
+unique indexes that, without regard to order, contain exactly the
+\fIconflict_target\fR\-specified columns/expressions are inferred (chosen) as arbiter indexes\&. If an
+\fIindex_predicate\fR
+is specified, it must, as a further requirement for inference, satisfy arbiter indexes\&. Note that this means a non\-partial unique index (a unique index without a predicate) will be inferred (and thus used by
+ON CONFLICT) if such an index satisfying every other criteria is available\&. If an attempt at inference is unsuccessful, an error is raised\&.
+.PP
+ON CONFLICT DO UPDATE
+guarantees an atomic
+\fBINSERT\fR
+or
+\fBUPDATE\fR
+outcome; provided there is no independent error, one of those two outcomes is guaranteed, even under high concurrency\&. This is also known as
+UPSERT
+\(em
+\(lqUPDATE or INSERT\(rq\&.
+.PP
+\fIconflict_target\fR
+.RS 4
+Specifies which conflicts
+ON CONFLICT
+takes the alternative action on by choosing
+arbiter indexes\&. Either performs
+\fIunique index inference\fR, or names a constraint explicitly\&. For
+ON CONFLICT DO NOTHING, it is optional to specify a
+\fIconflict_target\fR; when omitted, conflicts with all usable constraints (and unique indexes) are handled\&. For
+ON CONFLICT DO UPDATE, a
+\fIconflict_target\fR
+\fImust\fR
+be provided\&.
+.RE
+.PP
+\fIconflict_action\fR
+.RS 4
+\fIconflict_action\fR
+specifies an alternative
+ON CONFLICT
+action\&. It can be either
+DO NOTHING, or a
+DO UPDATE
+clause specifying the exact details of the
+UPDATE
+action to be performed in case of a conflict\&. The
+SET
+and
+WHERE
+clauses in
+ON CONFLICT DO UPDATE
+have access to the existing row using the table\*(Aqs name (or an alias), and to the row proposed for insertion using the special
+\fIexcluded\fR
+table\&.
+SELECT
+privilege is required on any column in the target table where corresponding
+\fIexcluded\fR
+columns are read\&.
+.sp
+Note that the effects of all per\-row
+BEFORE INSERT
+triggers are reflected in
+\fIexcluded\fR
+values, since those effects may have contributed to the row being excluded from insertion\&.

+\fIopclass\fR
+.RS 4
+When specified, mandates that corresponding
+\fIindex_column_name\fR

+\fIindex_expression\fR
+use particular operator class in order to be matched during inference\&. Typically this is omitted, as the
+\fIequality\fR
+semantics are often equivalent across a type\*(Aqs operator classes anyway, or because it\*(Aqs sufficient to trust that the defined unique indexes have the pertinent definition of equality\&. Follows
+\fBCREATE INDEX\fR
+format\&.
+.RE
+.PP
+\fIindex_predicate\fR
+.RS 4
+Used to allow inference of partial unique indexes\&. Any indexes that satisfy the predicate (which need not actually be partial indexes) can be inferred\&. Follows

+SELECT
+privilege on any column appearing within
+\fIindex_predicate\fR
+is required\&.
+.RE
+.PP
+\fIconstraint_name\fR
+.RS 4
+Explicitly specifies an arbiter
+\fIconstraint\fR
+by name, rather than inferring a constraint or index\&.
+.RE
+.PP
+\fIcondition\fR
+.RS 4
+An expression that returns a value of type
+boolean\&. Only rows for which this expression returns
+true
+will be updated, although all rows will be locked when the
+ON CONFLICT DO UPDATE
+action is taken\&. Note that
+\fIcondition\fR
+is evaluated last, after a conflict has been identified as a candidate to update\&.
+.RE
+.PP
+Note that exclusion constraints are not supported as arbiters with
+ON CONFLICT DO UPDATE\&. In all cases, only
+NOT DEFERRABLE
+constraints and unique indexes are supported as arbiters\&.
+.PP
+\fBINSERT\fR
+with an
+ON CONFLICT DO UPDATE
+clause is a
+\(lqdeterministic\(rq
+statement\&. This means that the command will not be allowed to affect any single existing row more than once; a cardinality violation error will be raised when this situation arises\&. Rows proposed for insertion should not duplicate each other in terms of attributes constrained by an arbiter index or constraint\&.
+.PP
+Note that it is currently not supported for the
+ON CONFLICT DO UPDATE
+clause of an
+\fBINSERT\fR
+applied to a partitioned table to update the partition key of a conflicting row such that it requires the row be moved to a new partition\&.

+It is often preferable to use unique index inference rather than naming a constraint directly using
+ON CONFLICT ON CONSTRAINT
+\fI constraint_name\fR\&. Inference will continue to work correctly when the underlying index is replaced by another more or less equivalent index in an overlapping way, for example when using

+There is a race condition when first setting up a listening session: if concurrently\-committing transactions are sending notify events, exactly which of those will the newly listening session receive? The answer is that the session will receive all events committed after an instant during the transaction\*(Aqs commit step\&. But that is slightly later than any database state that the transaction could have observed in queries\&. This leads to the following rule for using
+\fBLISTEN\fR: first execute (and commit!) that command, then in a new transaction inspect the database state as needed by the application logic, then rely on notifications to find out about subsequent changes to the database state\&.

+LOCK [ TABLE ] [ ONLY ] \fIname\fR [ * ] [, \&.\&.\&.] [ IN \fIlockmode\fR MODE ] [ NOWAIT ]
+
+where \fIlockmode\fR is one of:
+
+    ACCESS SHARE | ROW SHARE | ROW EXCLUSIVE | SHARE UPDATE EXCLUSIVE
+    | SHARE | SHARE ROW EXCLUSIVE | EXCLUSIVE | ACCESS EXCLUSIVE
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBLOCK TABLE\fR
+obtains a table\-level lock, waiting if necessary for any conflicting locks to be released\&. If
+NOWAIT
+is specified,
+\fBLOCK TABLE\fR
+does not wait to acquire the desired lock: if it cannot be acquired immediately, the command is aborted and an error is emitted\&. Once obtained, the lock is held for the remainder of the current transaction\&. (There is no
+\fBUNLOCK TABLE\fR
+command; locks are always released at transaction end\&.)
+.PP
+When a view is locked, all relations appearing in the view definition query are also locked recursively with the same lock mode\&.
+.PP
+When acquiring locks automatically for commands that reference tables,
+PostgreSQL
+always uses the least restrictive lock mode possible\&.
+\fBLOCK TABLE\fR
+provides for cases when you might need more restrictive locking\&. For example, suppose an application runs a transaction at the
+READ COMMITTED
+isolation level and needs to ensure that data in a table remains stable for the duration of the transaction\&. To achieve this you could obtain
+SHARE
+lock mode over the table before querying\&. This will prevent concurrent data changes and ensure subsequent reads of the table see a stable view of committed data, because
+SHARE
+lock mode conflicts with the
+ROW EXCLUSIVE
+lock acquired by writers, and your
+\fBLOCK TABLE \fR\fB\fIname\fR\fR\fB IN SHARE MODE\fR
+statement will wait until any concurrent holders of
+ROW EXCLUSIVE
+mode locks commit or roll back\&. Thus, once you obtain the lock, there are no uncommitted writes outstanding; furthermore none can begin until you release the lock\&.
+.PP
+To achieve a similar effect when running a transaction at the
+REPEATABLE READ
+or
+SERIALIZABLE
+isolation level, you have to execute the
+\fBLOCK TABLE\fR
+statement before executing any
+\fBSELECT\fR
+or data modification statement\&. A
+REPEATABLE READ
+or
+SERIALIZABLE
+transaction\*(Aqs view of data will be frozen when its first
+\fBSELECT\fR
+or data modification statement begins\&. A
+\fBLOCK TABLE\fR
+later in the transaction will still prevent concurrent writes \(em but it won\*(Aqt ensure that what the transaction reads corresponds to the latest committed values\&.
+.PP
+If a transaction of this sort is going to change the data in the table, then it should use
+SHARE ROW EXCLUSIVE
+lock mode instead of
+SHARE
+mode\&. This ensures that only one transaction of this type runs at a time\&. Without this, a deadlock is possible: two transactions might both acquire
+SHARE
+mode, and then be unable to also acquire
+ROW EXCLUSIVE
+mode to actually perform their updates\&. (Note that a transaction\*(Aqs own locks never conflict, so a transaction can acquire
+ROW EXCLUSIVE
+mode when it holds
+SHARE
+mode \(em but not if anyone else holds
+SHARE
+mode\&.) To avoid deadlocks, make sure all transactions acquire locks on the same objects in the same order, and if multiple lock modes are involved for a single object, then transactions should always acquire the most restrictive mode first\&.
+.PP
+More information about the lock modes and locking strategies can be found in
+Section\ \&13.3\&.

+.PP
+The user performing the lock on the view must have the corresponding privilege on the view\&. In addition, by default, the view\*(Aqs owner must have the relevant privileges on the underlying base relations, whereas the user performing the lock does not need any permissions on the underlying base relations\&. However, if the view has

+true
+(see
+\fBCREATE VIEW\fR), the user performing the lock, rather than the view owner, must have the relevant privileges on the underlying base relations\&.
+.PP
+\fBLOCK TABLE\fR
+is useless outside a transaction block: the lock would remain held only to the completion of the statement\&. Therefore

+\fBLOCK\fR
+is used outside a transaction block\&. Use
+\fBBEGIN\fR
+and
+\fBCOMMIT\fR
+(or
+\fBROLLBACK\fR) to define a transaction block\&.
+.PP
+\fBLOCK TABLE\fR
+only deals with table\-level locks, and so the mode names involving
+ROW
+are all misnomers\&. These mode names should generally be read as indicating the intention of the user to acquire row\-level locks within the locked table\&. Also,
+ROW EXCLUSIVE
+mode is a shareable table lock\&. Keep in mind that all the lock modes have identical semantics so far as
+\fBLOCK TABLE\fR
+is concerned, differing only in the rules about which modes conflict with which\&. For information on how to acquire an actual row\-level lock, see

+\fBMERGE\fR
+provides a single

+statement that can conditionally
+\fBINSERT\fR,
+\fBUPDATE\fR

+rows, a task that would otherwise require multiple procedural language statements\&.
+.PP
+First, the
+\fBMERGE\fR
+command performs a join from
+\fIdata_source\fR
+to
+\fItarget_table_name\fR
+producing zero or more candidate change rows\&. For each candidate change row, the status of
+MATCHED
+or
+NOT MATCHED
+is set just once, after which
+WHEN
+clauses are evaluated in the order specified\&. For each candidate change row, the first clause to evaluate as true is executed\&. No more than one
+WHEN
+clause is executed for any candidate change row\&.
+.PP
+\fBMERGE\fR
+actions have the same effect as regular
+\fBUPDATE\fR,
+\fBINSERT\fR, or
+\fBDELETE\fR
+commands of the same names\&. The syntax of those commands is different, notably that there is no
+WHERE
+clause and no table name is specified\&. All actions refer to the
+\fItarget_table_name\fR, though modifications to other tables may be made using triggers\&.
+.PP
+When
+DO NOTHING
+is specified, the source row is skipped\&. Since actions are evaluated in their specified order,
+DO NOTHING
+can be handy to skip non\-interesting source rows before more fine\-grained handling\&.
+.PP
+There is no separate
+MERGE
+privilege\&. If you specify an update action, you must have the
+UPDATE
+privilege on the column(s) of the
+\fItarget_table_name\fR
+that are referred to in the
+SET
+clause\&. If you specify an insert action, you must have the
+INSERT
+privilege on the
+\fItarget_table_name\fR\&. If you specify an delete action, you must have the
+DELETE
+privilege on the
+\fItarget_table_name\fR\&. Privileges are tested once at statement start and are checked whether or not particular
+WHEN
+clauses are executed\&. You will require the

+\fItarget_table_name\fR
+referred to in a

+\fBINSERT\fR, even though only
+\fBUPDATE\fR
+row triggers were fired\&.
+.PP
+You should ensure that the join produces at most one candidate change row for each target row\&. In other words, a target row shouldn\*(Aqt join to more than one data source row\&. If it does, then only one of the candidate change rows will be used to modify the target row; later attempts to modify the row will cause an error\&. This can also occur if row triggers make changes to the target table and the rows so modified are then subsequently also modified by
+\fBMERGE\fR\&. If the repeated action is an
+\fBINSERT\fR, this will cause a uniqueness violation, while a repeated
+\fBUPDATE\fR
+or
+\fBDELETE\fR
+will cause a cardinality violation; the latter behavior is required by the
+SQL
+standard\&. This differs from historical
+PostgreSQL
+behavior of joins in
+\fBUPDATE\fR
+and
+\fBDELETE\fR
+statements where second and subsequent attempts to modify the same row are simply ignored\&.
+.PP
+If a
+WHEN
+clause omits an
+AND
+sub\-clause, it becomes the final reachable clause of that kind (MATCHED
+or
+NOT MATCHED)\&. If a later
+WHEN
+clause of that kind is specified it would be provably unreachable and an error is raised\&. If no final reachable clause is specified of either kind, it is possible that no action will be taken for a candidate change row\&.
+.PP
+The order in which rows are generated from the data source is indeterminate by default\&. A

+NOTIFY \- generate a notification
+.SH "SYNOPSIS"
+.sp
+.nf
+NOTIFY \fIchannel\fR [ , \fIpayload\fR ]
+.fi
+.SH "DESCRIPTION"
+.PP
+The
+\fBNOTIFY\fR
+command sends a notification event together with an optional
+\(lqpayload\(rq
+string to each client application that has previously executed
+\fBLISTEN \fR\fB\fIchannel\fR\fR
+for the specified channel name in the current database\&. Notifications are visible to all users\&.
+.PP
+\fBNOTIFY\fR
+provides a simple interprocess communication mechanism for a collection of processes accessing the same
+PostgreSQL
+database\&. A payload string can be sent along with the notification, and higher\-level mechanisms for passing structured data can be built by using tables in the database to pass additional data from notifier to listener(s)\&.
+.PP
+The information passed to the client for a notification event includes the notification channel name, the notifying session\*(Aqs server process
+PID, and the payload string, which is an empty string if it has not been specified\&.
+.PP
+It is up to the database designer to define the channel names that will be used in a given database and what each one means\&. Commonly, the channel name is the same as the name of some table in the database, and the notify event essentially means,
+\(lqI changed this table, take a look at it to see what\*(Aqs new\(rq\&. But no such association is enforced by the
+\fBNOTIFY\fR
+and
+\fBLISTEN\fR
+commands\&. For example, a database designer could use several different channel names to signal different sorts of changes to a single table\&. Alternatively, the payload string could be used to differentiate various cases\&.
+.PP
+When
+\fBNOTIFY\fR
+is used to signal the occurrence of changes to a particular table, a useful programming technique is to put the
+\fBNOTIFY\fR
+in a statement trigger that is triggered by table updates\&. In this way, notification happens automatically when the table is changed, and the application programmer cannot accidentally forget to do it\&.
+.PP
+\fBNOTIFY\fR
+interacts with SQL transactions in some important ways\&. Firstly, if a
+\fBNOTIFY\fR
+is executed inside a transaction, the notify events are not delivered until and unless the transaction is committed\&. This is appropriate, since if the transaction is aborted, all the commands within it have had no effect, including
+\fBNOTIFY\fR\&. But it can be disconcerting if one is expecting the notification events to be delivered immediately\&. Secondly, if a listening session receives a notification signal while it is within a transaction, the notification event will not be delivered to its connected client until just after the transaction is completed (either committed or aborted)\&. Again, the reasoning is that if a notification were delivered within a transaction that was later aborted, one would want the notification to be undone somehow \(em but the server cannot
+\(lqtake back\(rq
+a notification once it has sent it to the client\&. So notification events are only delivered between transactions\&. The upshot of this is that applications using
+\fBNOTIFY\fR
+for real\-time signaling should try to keep their transactions short\&.
+.PP
+If the same channel name is signaled multiple times with identical payload strings within the same transaction, only one instance of the notification event is delivered to listeners\&. On the other hand, notifications with distinct payload strings will always be delivered as distinct notifications\&. Similarly, notifications from different transactions will never get folded into one notification\&. Except for dropping later instances of duplicate notifications,
+\fBNOTIFY\fR
+guarantees that notifications from the same transaction get delivered in the order they were sent\&. It is also guaranteed that messages from different transactions are delivered in the order in which the transactions committed\&.
+.PP
+It is common for a client that executes
+\fBNOTIFY\fR
+to be listening on the same notification channel itself\&. In that case it will get back a notification event, just like all the other listening sessions\&. Depending on the application logic, this could result in useless work, for example, reading a database table to find the same updates that that session just wrote out\&. It is possible to avoid such extra work by noticing whether the notifying session\*(Aqs server process
+PID
+(supplied in the notification event message) is the same as one\*(Aqs own session\*(Aqs
+PID
+(available from
+libpq)\&. When they are the same, the notification event is one\*(Aqs own work bouncing back, and can be ignored\&.
+.SH "PARAMETERS"
+.PP
+\fIchannel\fR
+.RS 4
+Name of the notification channel to be signaled (any identifier)\&.
+.RE
+.PP
+\fIpayload\fR
+.RS 4
+The
+\(lqpayload\(rq
+string to be communicated along with the notification\&. This must be specified as a simple string literal\&. In the default configuration it must be shorter than 8000 bytes\&. (If binary data or large amounts of information need to be communicated, it\*(Aqs best to put it in a database table and send the key of the record\&.)
+.RE
+.SH "NOTES"
+.PP
+There is a queue that holds notifications that have been sent but not yet processed by all listening sessions\&. If this queue becomes full, transactions calling
+\fBNOTIFY\fR
+will fail at commit\&. The queue is quite large (8GB in a standard installation) and should be sufficiently sized for almost every use case\&. However, no cleanup can take place if a session executes
+\fBLISTEN\fR
+and then enters a transaction for a very long time\&. Once the queue is half full you will see warnings in the log file pointing you to the session that is preventing cleanup\&. In this case you should make sure that this session ends its current transaction so that cleanup can proceed\&.
+.PP
+The function
+\fBpg_notification_queue_usage\fR
+returns the fraction of the queue that is currently occupied by pending notifications\&. See
+Section\ \&9.26
+for more information\&.
+.PP
+A transaction that has executed
+\fBNOTIFY\fR
+cannot be prepared for two\-phase commit\&.
+.SS "pg_notify"
+.PP
+To send a notification you can also use the function
+\fBpg_notify\fR(text, text)\&. The function takes the channel name as the first argument and the payload as the second\&. The function is much easier to use than the
+\fBNOTIFY\fR

+PREPARE \- prepare a statement for execution
+.SH "SYNOPSIS"
+.sp
+.nf
+PREPARE \fIname\fR [ ( \fIdata_type\fR [, \&.\&.\&.] ) ] AS \fIstatement\fR
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBPREPARE\fR
+creates a prepared statement\&. A prepared statement is a server\-side object that can be used to optimize performance\&. When the
+\fBPREPARE\fR
+statement is executed, the specified statement is parsed, analyzed, and rewritten\&. When an
+\fBEXECUTE\fR
+command is subsequently issued, the prepared statement is planned and executed\&. This division of labor avoids repetitive parse analysis work, while allowing the execution plan to depend on the specific parameter values supplied\&.
+.PP
+Prepared statements can take parameters: values that are substituted into the statement when it is executed\&. When creating the prepared statement, refer to parameters by position, using
+$1,
+$2, etc\&. A corresponding list of parameter data types can optionally be specified\&. When a parameter\*(Aqs data type is not specified or is declared as
+unknown, the type is inferred from the context in which the parameter is first referenced (if possible)\&. When executing the statement, specify the actual values for these parameters in the
+\fBEXECUTE\fR
+statement\&. Refer to
+\fBEXECUTE\fR(7)
+for more information about that\&.
+.PP
+Prepared statements only last for the duration of the current database session\&. When the session ends, the prepared statement is forgotten, so it must be recreated before being used again\&. This also means that a single prepared statement cannot be used by multiple simultaneous database clients; however, each client can create their own prepared statement to use\&. Prepared statements can be manually cleaned up using the
+\fBDEALLOCATE\fR
+command\&.
+.PP
+Prepared statements potentially have the largest performance advantage when a single session is being used to execute a large number of similar statements\&. The performance difference will be particularly significant if the statements are complex to plan or rewrite, e\&.g\&., if the query involves a join of many tables or requires the application of several rules\&. If the statement is relatively simple to plan and rewrite but relatively expensive to execute, the performance advantage of prepared statements will be less noticeable\&.
+.SH "PARAMETERS"
+.PP
+\fIname\fR
+.RS 4
+An arbitrary name given to this particular prepared statement\&. It must be unique within a single session and is subsequently used to execute or deallocate a previously prepared statement\&.
+.RE
+.PP
+\fIdata_type\fR
+.RS 4
+The data type of a parameter to the prepared statement\&. If the data type of a particular parameter is unspecified or is specified as
+unknown, it will be inferred from the context in which the parameter is first referenced\&. To refer to the parameters in the prepared statement itself, use
+$1,
+$2, etc\&.
+.RE
+.PP
+\fIstatement\fR
+.RS 4
+Any
+\fBSELECT\fR,
+\fBINSERT\fR,
+\fBUPDATE\fR,
+\fBDELETE\fR,
+\fBMERGE\fR, or
+\fBVALUES\fR
+statement\&.
+.RE
+.SH "NOTES"
+.PP
+A prepared statement can be executed with either a
+generic plan
+or a
+custom plan\&. A generic plan is the same across all executions, while a custom plan is generated for a specific execution using the parameter values given in that call\&. Use of a generic plan avoids planning overhead, but in some situations a custom plan will be much more efficient to execute because the planner can make use of knowledge of the parameter values\&. (Of course, if the prepared statement has no parameters, then this is moot and a generic plan is always used\&.)
+.PP
+By default (that is, when
+plan_cache_mode
+is set to
+auto), the server will automatically choose whether to use a generic or custom plan for a prepared statement that has parameters\&. The current rule for this is that the first five executions are done with custom plans and the average estimated cost of those plans is calculated\&. Then a generic plan is created and its estimated cost is compared to the average custom\-plan cost\&. Subsequent executions use the generic plan if its cost is not so much higher than the average custom\-plan cost as to make repeated replanning seem preferable\&.
+.PP
+This heuristic can be overridden, forcing the server to use either generic or custom plans, by setting
+\fIplan_cache_mode\fR
+to
+force_generic_plan
+or
+force_custom_plan
+respectively\&. This setting is primarily useful if the generic plan\*(Aqs cost estimate is badly off for some reason, allowing it to be chosen even though its actual cost is much more than that of a custom plan\&.
+.PP
+To examine the query plan
+PostgreSQL
+is using for a prepared statement, use
+\fBEXPLAIN\fR, for example
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+EXPLAIN EXECUTE \fIname\fR(\fIparameter_values\fR);
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+If a generic plan is in use, it will contain parameter symbols
+$\fIn\fR, while a custom plan will have the supplied parameter values substituted into it\&.
+.PP
+For more information on query planning and the statistics collected by
+PostgreSQL
+for that purpose, see the
+\fBANALYZE\fR(7)
+documentation\&.
+.PP
+Although the main point of a prepared statement is to avoid repeated parse analysis and planning of the statement,
+PostgreSQL
+will force re\-analysis and re\-planning of the statement before using it whenever database objects used in the statement have undergone definitional (DDL) changes or their planner statistics have been updated since the previous use of the prepared statement\&. Also, if the value of
+search_path
+changes from one use to the next, the statement will be re\-parsed using the new
+\fIsearch_path\fR\&. (This latter behavior is new as of
+PostgreSQL
+9\&.3\&.) These rules make use of a prepared statement semantically almost equivalent to re\-submitting the same query text over and over, but with a performance benefit if no object definitions are changed, especially if the best plan remains the same across uses\&. An example of a case where the semantic equivalence is not perfect is that if the statement refers to a table by an unqualified name, and then a new table of the same name is created in a schema appearing earlier in the
+\fIsearch_path\fR, no automatic re\-parse will occur since no object used in the statement changed\&. However, if some other change forces a re\-parse, the new table will be referenced in subsequent uses\&.
+.PP
+You can see all prepared statements available in the session by querying the
+pg_prepared_statements
+system view\&.
+.SH "EXAMPLES"
+.PP
+Create a prepared statement for an
+\fBINSERT\fR
+statement, and then execute it:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+PREPARE fooplan (int, text, bool, numeric) AS
+    INSERT INTO foo VALUES($1, $2, $3, $4);
+EXECUTE fooplan(1, \*(AqHunter Valley\*(Aq, \*(Aqt\*(Aq, 200\&.00);
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Create a prepared statement for a
+\fBSELECT\fR
+statement, and then execute it:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+PREPARE usrrptplan (int) AS
+    SELECT * FROM users u, logs l WHERE u\&.usrid=$1 AND u\&.usrid=l\&.usrid
+    AND l\&.date = $2;
+EXECUTE usrrptplan(1, current_date);
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+In this example, the data type of the second parameter is not specified, so it is inferred from the context in which
+$2
+is used\&.
+.SH "COMPATIBILITY"
+.PP
+The SQL standard includes a
+\fBPREPARE\fR
+statement, but it is only for use in embedded SQL\&. This version of the
+\fBPREPARE\fR
+statement also uses a somewhat different syntax\&.

+PREPARE_TRANSACTION \- prepare the current transaction for two\-phase commit
+.SH "SYNOPSIS"
+.sp
+.nf
+PREPARE TRANSACTION \fItransaction_id\fR
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBPREPARE TRANSACTION\fR
+prepares the current transaction for two\-phase commit\&. After this command, the transaction is no longer associated with the current session; instead, its state is fully stored on disk, and there is a very high probability that it can be committed successfully, even if a database crash occurs before the commit is requested\&.
+.PP
+Once prepared, a transaction can later be committed or rolled back with
+\fBCOMMIT PREPARED\fR
+or
+\fBROLLBACK PREPARED\fR, respectively\&. Those commands can be issued from any session, not only the one that executed the original transaction\&.
+.PP
+From the point of view of the issuing session,
+\fBPREPARE TRANSACTION\fR
+is not unlike a
+\fBROLLBACK\fR
+command: after executing it, there is no active current transaction, and the effects of the prepared transaction are no longer visible\&. (The effects will become visible again if the transaction is committed\&.)
+.PP
+If the
+\fBPREPARE TRANSACTION\fR
+command fails for any reason, it becomes a
+\fBROLLBACK\fR: the current transaction is canceled\&.
+.SH "PARAMETERS"
+.PP
+\fItransaction_id\fR
+.RS 4
+An arbitrary identifier that later identifies this transaction for
+\fBCOMMIT PREPARED\fR
+or
+\fBROLLBACK PREPARED\fR\&. The identifier must be written as a string literal, and must be less than 200 bytes long\&. It must not be the same as the identifier used for any currently prepared transaction\&.
+.RE
+.SH "NOTES"
+.PP
+\fBPREPARE TRANSACTION\fR
+is not intended for use in applications or interactive sessions\&. Its purpose is to allow an external transaction manager to perform atomic global transactions across multiple databases or other transactional resources\&. Unless you\*(Aqre writing a transaction manager, you probably shouldn\*(Aqt be using
+\fBPREPARE TRANSACTION\fR\&.
+.PP
+This command must be used inside a transaction block\&. Use
+\fBBEGIN\fR
+to start one\&.
+.PP
+It is not currently allowed to
+\fBPREPARE\fR
+a transaction that has executed any operations involving temporary tables or the session\*(Aqs temporary namespace, created any cursors
+WITH HOLD, or executed
+\fBLISTEN\fR,
+\fBUNLISTEN\fR, or
+\fBNOTIFY\fR\&. Those features are too tightly tied to the current session to be useful in a transaction to be prepared\&.
+.PP
+If the transaction modified any run\-time parameters with
+\fBSET\fR
+(without the
+LOCAL
+option), those effects persist after
+\fBPREPARE TRANSACTION\fR, and will not be affected by any later
+\fBCOMMIT PREPARED\fR
+or
+\fBROLLBACK PREPARED\fR\&. Thus, in this one respect
+\fBPREPARE TRANSACTION\fR
+acts more like
+\fBCOMMIT\fR
+than
+\fBROLLBACK\fR\&.
+.PP
+All currently available prepared transactions are listed in the
+pg_prepared_xacts
+system view\&.

+.PP
+It is unwise to leave transactions in the prepared state for a long time\&. This will interfere with the ability of
+\fBVACUUM\fR
+to reclaim storage, and in extreme cases could cause the database to shut down to prevent transaction ID wraparound (see
+Section\ \&25.1.5)\&. Keep in mind also that the transaction continues to hold whatever locks it held\&. The intended usage of the feature is that a prepared transaction will normally be committed or rolled back as soon as an external transaction manager has verified that other databases are also prepared to commit\&.
+.PP
+If you have not set up an external transaction manager to track prepared transactions and ensure they get closed out promptly, it is best to keep the prepared\-transaction feature disabled by setting
+max_prepared_transactions
+to zero\&. This will prevent accidental creation of prepared transactions that might then be forgotten and eventually cause problems\&.

+.SH "NOTES"
+.PP
+If you suspect corruption of an index on a user table, you can simply rebuild that index, or all indexes on the table, using
+\fBREINDEX INDEX\fR
+or
+\fBREINDEX TABLE\fR\&.
+.PP
+Things are more difficult if you need to recover from corruption of an index on a system table\&. In this case it\*(Aqs important for the system to not have used any of the suspect indexes itself\&. (Indeed, in this sort of scenario you might find that server processes are crashing immediately at start\-up, due to reliance on the corrupted indexes\&.) To recover safely, the server must be started with the
+\fB\-P\fR
+option, which prevents it from using indexes for system catalog lookups\&.
+.PP
+One way to do this is to shut down the server and start a single\-user
+PostgreSQL
+server with the
+\fB\-P\fR
+option included on its command line\&. Then,
+\fBREINDEX DATABASE\fR,
+\fBREINDEX SYSTEM\fR,
+\fBREINDEX TABLE\fR, or
+\fBREINDEX INDEX\fR
+can be issued, depending on how much you want to reconstruct\&. If in doubt, use
+\fBREINDEX SYSTEM\fR
+to select reconstruction of all system indexes in the database\&. Then quit the single\-user server session and restart the regular server\&. See the
+\fBpostgres\fR(1)
+reference page for more information about how to interact with the single\-user server interface\&.
+.PP
+Alternatively, a regular server session can be started with
+\fB\-P\fR
+included in its command line options\&. The method for doing this varies across clients, but in all
+libpq\-based clients, it is possible to set the
+\fBPGOPTIONS\fR
+environment variable to
+\-P
+before starting the client\&. Note that while this method does not require locking out other clients, it might still be wise to prevent other users from connecting to the damaged database until repairs have been completed\&.
+.PP
+\fBREINDEX\fR
+is similar to a drop and recreate of the index in that the index contents are rebuilt from scratch\&. However, the locking considerations are rather different\&.
+\fBREINDEX\fR
+locks out writes but not reads of the index\*(Aqs parent table\&. It also takes an
+ACCESS EXCLUSIVE
+lock on the specific index being processed, which will block reads that attempt to use that index\&. In particular, the query planner tries to take an
+ACCESS SHARE
+lock on every index of the table, regardless of the query, and so
+\fBREINDEX\fR
+blocks virtually any queries except for some prepared queries whose plan has been cached and which don\*(Aqt use this very index\&. In contrast,
+\fBDROP INDEX\fR
+momentarily takes an
+ACCESS EXCLUSIVE
+lock on the parent table, blocking both writes and reads\&. The subsequent
+\fBCREATE INDEX\fR
+locks out writes but not reads; since the index is not there, no read will attempt to use it, meaning that there will be no blocking but reads might be forced into expensive sequential scans\&.
+.PP
+Reindexing a single index or table requires being the owner of that index or table\&. Reindexing a schema or database requires being the owner of that schema or database\&. Note specifically that it\*(Aqs thus possible for non\-superusers to rebuild indexes of tables owned by other users\&. However, as a special exception, when
+\fBREINDEX DATABASE\fR,
+\fBREINDEX SCHEMA\fR
+or
+\fBREINDEX SYSTEM\fR
+is issued by a non\-superuser, indexes on shared catalogs will be skipped unless the user owns the catalog (which typically won\*(Aqt be the case)\&. Of course, superusers can always reindex anything\&.
+.PP
+Reindexing partitioned indexes or partitioned tables is supported with
+\fBREINDEX INDEX\fR
+or
+\fBREINDEX TABLE\fR, respectively\&. Each partition of the specified partitioned relation is reindexed in a separate transaction\&. Those commands cannot be used inside a transaction block when working on a partitioned table or index\&.
+.PP
+When using the
+TABLESPACE
+clause with
+\fBREINDEX\fR
+on a partitioned index or table, only the tablespace references of the leaf partitions are updated\&. As partitioned indexes are not updated, it is recommended to separately use
+\fBALTER TABLE ONLY\fR
+on them so as any new partitions attached inherit the new tablespace\&. On failure, it may not have moved all the indexes to the new tablespace\&. Re\-running the command will rebuild all the leaf partitions and move previously\-unprocessed indexes to the new tablespace\&.
+.PP
+If
+SCHEMA,
+DATABASE
+or
+SYSTEM
+is used with
+TABLESPACE, system relations are skipped and a single
+WARNING
+will be generated\&. Indexes on TOAST tables are rebuilt, but not moved to the new tablespace\&.
+.SS "Rebuilding Indexes Concurrently"
+.PP
+Rebuilding an index can interfere with regular operation of a database\&. Normally
+PostgreSQL
+locks the table whose index is rebuilt against writes and performs the entire index build with a single scan of the table\&. Other transactions can still read the table, but if they try to insert, update, or delete rows in the table they will block until the index rebuild is finished\&. This could have a severe effect if the system is a live production database\&. Very large tables can take many hours to be indexed, and even for smaller tables, an index rebuild can lock out writers for periods that are unacceptably long for a production system\&.
+.PP
+PostgreSQL
+supports rebuilding indexes with minimum locking of writes\&. This method is invoked by specifying the
+CONCURRENTLY
+option of
+\fBREINDEX\fR\&. When this option is used,
+PostgreSQL
+must perform two scans of the table for each index that needs to be rebuilt and wait for termination of all existing transactions that could potentially use the index\&. This method requires more total work than a standard index rebuild and takes significantly longer to complete as it needs to wait for unfinished transactions that might modify the index\&. However, since it allows normal operations to continue while the index is being rebuilt, this method is useful for rebuilding indexes in a production environment\&. Of course, the extra CPU, memory and I/O load imposed by the index rebuild may slow down other operations\&.
+.PP
+The following steps occur in a concurrent reindex\&. Each step is run in a separate transaction\&. If there are multiple indexes to be rebuilt, then each step loops through all the indexes before moving to the next step\&.
+.sp
+.RS 4
+.ie n \{\
+\h'-04' 1.\h'+01'\c
+.\}
+.el \{\
+.sp -1
+.IP "  1." 4.2
+.\}
+A new transient index definition is added to the catalog
+pg_index\&. This definition will be used to replace the old index\&. A
+SHARE UPDATE EXCLUSIVE
+lock at session level is taken on the indexes being reindexed as well as their associated tables to prevent any schema modification while processing\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04' 2.\h'+01'\c
+.\}
+.el \{\
+.sp -1
+.IP "  2." 4.2
+.\}
+A first pass to build the index is done for each new index\&. Once the index is built, its flag
+pg_index\&.indisready
+is switched to
+\(lqtrue\(rq
+to make it ready for inserts, making it visible to other sessions once the transaction that performed the build is finished\&. This step is done in a separate transaction for each index\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04' 3.\h'+01'\c
+.\}
+.el \{\
+.sp -1
+.IP "  3." 4.2
+.\}
+Then a second pass is performed to add tuples that were added while the first pass was running\&. This step is also done in a separate transaction for each index\&.
+.RE

+\h'-04' 4.\h'+01'\c
+.\}
+.el \{\
+.sp -1
+.IP "  4." 4.2

+pg_index\&.indisvalid
+is switched to
+\(lqtrue\(rq
+for the new index and to
+\(lqfalse\(rq
+for the old, and a cache invalidation is done causing all sessions that referenced the old index to be invalidated\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04' 5.\h'+01'\c
+.\}
+.el \{\
+.sp -1
+.IP "  5." 4.2

+The old indexes have
+pg_index\&.indisready
+switched to

+.ie n \{\

+.\}
+.el \{\
+.sp -1
+.IP "  6." 4.2
+.\}
+The old indexes are dropped\&. The
+SHARE UPDATE EXCLUSIVE
+session locks for the indexes and the table are released\&.
+.RE
+.PP
+If a problem arises while rebuilding the indexes, such as a uniqueness violation in a unique index, the
+\fBREINDEX\fR
+command will fail but leave behind an
+\(lqinvalid\(rq
+new index in addition to the pre\-existing one\&. This index will be ignored for querying purposes because it might be incomplete; however it will still consume update overhead\&. The
+psql
+\fB\ed\fR
+command will report such an index as
+INVALID:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+postgres=# \ed tab
+       Table "public\&.tab"
+ Column |  Type   | Modifiers
+\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-\-\-\-
+ col    | integer |
+Indexes:
+    "idx" btree (col)
+    "idx_ccnew" btree (col) INVALID
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+If the index marked
+INVALID
+is suffixed
+ccnew, then it corresponds to the transient index created during the concurrent operation, and the recommended recovery method is to drop it using
+DROP INDEX, then attempt
+\fBREINDEX CONCURRENTLY\fR
+again\&. If the invalid index is instead suffixed
+ccold, it corresponds to the original index which could not be dropped; the recommended recovery method is to just drop said index, since the rebuild proper has been successful\&.
+.PP
+Regular index builds permit other regular index builds on the same table to occur simultaneously, but only one concurrent index build can occur on a table at a time\&. In both cases, no other types of schema modification on the table are allowed meanwhile\&. Another difference is that a regular
+\fBREINDEX TABLE\fR
+or
+\fBREINDEX INDEX\fR
+command can be performed within a transaction block, but
+\fBREINDEX CONCURRENTLY\fR
+cannot\&.
+.PP
+Like any long\-running transaction,
+\fBREINDEX\fR
+on a table can affect which tuples can be removed by concurrent
+\fBVACUUM\fR
+on any other table\&.
+.PP
+\fBREINDEX SYSTEM\fR
+does not support
+\fBCONCURRENTLY\fR
+since system catalogs cannot be reindexed concurrently\&.
+.PP
+Furthermore, indexes for exclusion constraints cannot be reindexed concurrently\&. If such an index is named directly in this command, an error is raised\&. If a table or database with exclusion constraint indexes is reindexed concurrently, those indexes will be skipped\&. (It is possible to reindex such indexes without the
+\fBCONCURRENTLY\fR

+.SH "DESCRIPTION"
+.PP
+The
+\fBREVOKE\fR
+command revokes previously granted privileges from one or more roles\&. The key word
+PUBLIC
+refers to the implicitly defined group of all roles\&.
+.PP
+See the description of the
+\fBGRANT\fR
+command for the meaning of the privilege types\&.
+.PP
+Note that any particular role will have the sum of privileges granted directly to it, privileges granted to any role it is presently a member of, and privileges granted to
+PUBLIC\&. Thus, for example, revoking
+SELECT
+privilege from
+PUBLIC
+does not necessarily mean that all roles have lost
+SELECT
+privilege on the object: those who have it granted directly or via another role will still have it\&. Similarly, revoking
+SELECT
+from a user might not prevent that user from using
+SELECT
+if
+PUBLIC
+or another membership role still has
+SELECT
+rights\&.
+.PP
+If
+GRANT OPTION FOR
+is specified, only the grant option for the privilege is revoked, not the privilege itself\&. Otherwise, both the privilege and the grant option are revoked\&.
+.PP
+If a user holds a privilege with grant option and has granted it to other users then the privileges held by those other users are called dependent privileges\&. If the privilege or the grant option held by the first user is being revoked and dependent privileges exist, those dependent privileges are also revoked if
+CASCADE
+is specified; if it is not, the revoke action will fail\&. This recursive revocation only affects privileges that were granted through a chain of users that is traceable to the user that is the subject of this
+REVOKE
+command\&. Thus, the affected users might effectively keep the privilege if it was also granted through other users\&.
+.PP
+When revoking privileges on a table, the corresponding column privileges (if any) are automatically revoked on each column of the table, as well\&. On the other hand, if a role has been granted privileges on a table, then revoking the same privileges from individual columns will have no effect\&.
+.PP
+When revoking membership in a role,
+GRANT OPTION
+is instead called
+ADMIN OPTION, but the behavior is similar\&. This form of the command also allows a
+GRANTED BY
+option, but that option is currently ignored (except for checking the existence of the named role)\&. Note also that this form of the command does not allow the noise word
+GROUP
+in
+\fIrole_specification\fR\&.
+.SH "NOTES"
+.PP
+A user can only revoke privileges that were granted directly by that user\&. If, for example, user A has granted a privilege with grant option to user B, and user B has in turn granted it to user C, then user A cannot revoke the privilege directly from C\&. Instead, user A could revoke the grant option from user B and use the
+CASCADE
+option so that the privilege is in turn revoked from user C\&. For another example, if both A and B have granted the same privilege to C, A can revoke their own grant but not B\*(Aqs grant, so C will still effectively have the privilege\&.
+.PP
+When a non\-owner of an object attempts to
+\fBREVOKE\fR
+privileges on the object, the command will fail outright if the user has no privileges whatsoever on the object\&. As long as some privilege is available, the command will proceed, but it will revoke only those privileges for which the user has grant options\&. The
+\fBREVOKE ALL PRIVILEGES\fR
+forms will issue a warning message if no grant options are held, while the other forms will issue a warning if grant options for any of the privileges specifically named in the command are not held\&. (In principle these statements apply to the object owner as well, but since the owner is always treated as holding all grant options, the cases can never occur\&.)
+.PP
+If a superuser chooses to issue a
+\fBGRANT\fR
+or
+\fBREVOKE\fR
+command, the command is performed as though it were issued by the owner of the affected object\&. Since all privileges ultimately come from the object owner (possibly indirectly via chains of grant options), it is possible for a superuser to revoke all privileges, but this might require use of
+CASCADE
+as stated above\&.
+.PP
+\fBREVOKE\fR
+can also be done by a role that is not the owner of the affected object, but is a member of the role that owns the object, or is a member of a role that holds privileges
+WITH GRANT OPTION
+on the object\&. In this case the command is performed as though it were issued by the containing role that actually owns the object or holds the privileges
+WITH GRANT OPTION\&. For example, if table
+t1
+is owned by role
+g1, of which role
+u1
+is a member, then
+u1
+can revoke privileges on
+t1
+that are recorded as being granted by
+g1\&. This would include grants made by
+u1
+as well as by other members of role
+g1\&.
+.PP
+If the role executing
+\fBREVOKE\fR
+holds privileges indirectly via more than one role membership path, it is unspecified which containing role will be used to perform the command\&. In such cases it is best practice to use
+\fBSET ROLE\fR
+to become the specific role you want to do the
+\fBREVOKE\fR
+as\&. Failure to do so might lead to revoking privileges other than the ones you intended, or not revoking anything at all\&.
+.PP
+See
+Section\ \&5.7
+for more information about specific privilege types, as well as how to inspect objects\*(Aq privileges\&.
+.SH "EXAMPLES"
+.PP
+Revoke insert privilege for the public on table
+films:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+REVOKE INSERT ON films FROM PUBLIC;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Revoke all privileges from user
+manuel

+kinds:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+REVOKE ALL PRIVILEGES ON kinds FROM manuel;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Note that this actually means
+\(lqrevoke all privileges that I granted\(rq\&.
+.PP
+Revoke membership in role
+admins
+from user
+joe:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+REVOKE admins FROM joe;
+.fi
+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"
+.PP
+The compatibility notes of the
+\fBGRANT\fR
+command apply analogously to
+\fBREVOKE\fR\&. The keyword
+RESTRICT
+or
+CASCADE
+is required according to the standard, but
+PostgreSQL
+assumes
+RESTRICT
+by default\&.

+The label provider determines whether a given label is valid and whether it is permissible to assign that label to a given object\&. The meaning of a given label is likewise at the discretion of the label provider\&.
+PostgreSQL
+places no restrictions on whether or how a label provider must interpret security labels; it merely provides a mechanism for storing them\&. In practice, this facility is intended to allow integration with label\-based mandatory access control (MAC) systems such as
+SELinux\&. Such systems make all access control decisions based on object labels, rather than traditional discretionary access control (DAC) concepts such as users and groups\&.

+requires

+.SH "PARAMETERS"
+.SS "WITH Clause"
+.PP
+The
+WITH
+clause allows you to specify one or more subqueries that can be referenced by name in the primary query\&. The subqueries effectively act as temporary tables or views for the duration of the primary query\&. Each subquery can be a
+\fBSELECT\fR,
+\fBTABLE\fR,
+\fBVALUES\fR,
+\fBINSERT\fR,
+\fBUPDATE\fR
+or
+\fBDELETE\fR
+statement\&. When writing a data\-modifying statement (\fBINSERT\fR,
+\fBUPDATE\fR
+or
+\fBDELETE\fR) in
+WITH, it is usual to include a
+RETURNING
+clause\&. It is the output of
+RETURNING,
+\fInot\fR
+the underlying table that the statement modifies, that forms the temporary table that is read by the primary query\&. If
+RETURNING
+is omitted, the statement is still executed, but it produces no output so it cannot be referenced as a table by the primary query\&.
+.PP
+A name (without schema qualification) must be specified for each
+WITH
+query\&. Optionally, a list of column names can be specified; if this is omitted, the column names are inferred from the subquery\&.
+.PP
+If
+RECURSIVE
+is specified, it allows a
+\fBSELECT\fR
+subquery to reference itself by name\&. Such a subquery must have the form
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+\fInon_recursive_term\fR UNION [ ALL | DISTINCT ] \fIrecursive_term\fR
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+where the recursive self\-reference must appear on the right\-hand side of the
+UNION\&. Only one recursive self\-reference is permitted per query\&. Recursive data\-modifying statements are not supported, but you can use the results of a recursive
+\fBSELECT\fR
+query in a data\-modifying statement\&. See
+Section\ \&7.8
+for an example\&.
+.PP
+Another effect of
+RECURSIVE
+is that
+WITH
+queries need not be ordered: a query can reference another one that is later in the list\&. (However, circular references, or mutual recursion, are not implemented\&.) Without
+RECURSIVE,
+WITH
+queries can only reference sibling
+WITH
+queries that are earlier in the
+WITH
+list\&.
+.PP
+When there are multiple queries in the
+WITH
+clause,
+RECURSIVE
+should be written only once, immediately after
+WITH\&. It applies to all queries in the
+WITH
+clause, though it has no effect on queries that do not use recursion or forward references\&.
+.PP
+The optional
+SEARCH
+clause computes a
+search sequence column
+that can be used for ordering the results of a recursive query in either breadth\-first or depth\-first order\&. The supplied column name list specifies the row key that is to be used for keeping track of visited rows\&. A column named
+\fIsearch_seq_col_name\fR
+will be added to the result column list of the
+WITH
+query\&. This column can be ordered by in the outer query to achieve the respective ordering\&. See
+Section\ \&7.8.2.1
+for examples\&.
+.PP
+The optional
+CYCLE
+clause is used to detect cycles in recursive queries\&. The supplied column name list specifies the row key that is to be used for keeping track of visited rows\&. A column named
+\fIcycle_mark_col_name\fR
+will be added to the result column list of the
+WITH
+query\&. This column will be set to
+\fIcycle_mark_value\fR
+when a cycle has been detected, else to
+\fIcycle_mark_default\fR\&. Furthermore, processing of the recursive union will stop when a cycle has been detected\&.
+\fIcycle_mark_value\fR
+and
+\fIcycle_mark_default\fR
+must be constants and they must be coercible to a common data type, and the data type must have an inequality operator\&. (The SQL standard requires that they be Boolean constants or character strings, but PostgreSQL does not require that\&.) By default,
+TRUE
+and
+FALSE
+(of type
+boolean) are used\&. Furthermore, a column named
+\fIcycle_path_col_name\fR
+will be added to the result column list of the
+WITH
+query\&. This column is used internally for tracking visited rows\&. See
+Section\ \&7.8.2.2
+for examples\&.
+.PP
+Both the
+SEARCH
+and the
+CYCLE
+clause are only valid for recursive
+WITH
+queries\&. The
+\fIwith_query\fR
+must be a
+UNION
+(or
+UNION ALL) of two
+SELECT
+(or equivalent) commands (no nested
+UNIONs)\&. If both clauses are used, the column added by the
+SEARCH
+clause appears before the columns added by the
+CYCLE
+clause\&.
+.PP
+The primary query and the
+WITH
+queries are all (notionally) executed at the same time\&. This implies that the effects of a data\-modifying statement in
+WITH
+cannot be seen from other parts of the query, other than by reading its
+RETURNING
+output\&. If two such data\-modifying statements attempt to modify the same row, the results are unspecified\&.
+.PP
+A key property of
+WITH
+queries is that they are normally evaluated only once per execution of the primary query, even if the primary query refers to them more than once\&. In particular, data\-modifying statements are guaranteed to be executed once and only once, regardless of whether the primary query reads all or any of their output\&.
+.PP
+However, a
+WITH
+query can be marked
+NOT MATERIALIZED
+to remove this guarantee\&. In that case, the
+WITH
+query can be folded into the primary query much as though it were a simple sub\-SELECT
+in the primary query\*(Aqs
+FROM
+clause\&. This results in duplicate computations if the primary query refers to that
+WITH
+query more than once; but if each such use requires only a few rows of the
+WITH
+query\*(Aqs total output,
+NOT MATERIALIZED
+can provide a net savings by allowing the queries to be optimized jointly\&.
+NOT MATERIALIZED
+is ignored if it is attached to a
+WITH
+query that is recursive or is not side\-effect\-free (i\&.e\&., is not a plain
+SELECT
+containing no volatile functions)\&.
+.PP
+By default, a side\-effect\-free
+WITH
+query is folded into the primary query if it is used exactly once in the primary query\*(Aqs
+FROM
+clause\&. This allows joint optimization of the two query levels in situations where that should be semantically invisible\&. However, such folding can be prevented by marking the
+WITH
+query as
+MATERIALIZED\&. That might be useful, for example, if the
+WITH
+query is being used as an optimization fence to prevent the planner from choosing a bad plan\&.
+PostgreSQL
+versions before v12 never did such folding, so queries written for older versions might rely on
+WITH
+to act as an optimization fence\&.
+.PP
+See
+Section\ \&7.8
+for additional information\&.
+.SS "FROM Clause"
+.PP
+The
+FROM
+clause specifies one or more source tables for the
+\fBSELECT\fR\&. If multiple sources are specified, the result is the Cartesian product (cross join) of all the sources\&. But usually qualification conditions are added (via
+WHERE) to restrict the returned rows to a small subset of the Cartesian product\&.
+.PP
+The
+FROM
+clause can contain the following elements:
+.PP
+\fItable_name\fR
+.RS 4
+The name (optionally schema\-qualified) of an existing table or view\&. If
+ONLY
+is specified before the table name, only that table is scanned\&. If
+ONLY
+is not specified, the table and all its descendant tables (if any) are scanned\&. Optionally,
+*
+can be specified after the table name to explicitly indicate that descendant tables are included\&.
+.RE
+.PP
+\fIalias\fR
+.RS 4
+A substitute name for the
+FROM
+item containing the alias\&. An alias is used for brevity or to eliminate ambiguity for self\-joins (where the same table is scanned multiple times)\&. When an alias is provided, it completely hides the actual name of the table or function; for example given
+FROM foo AS f, the remainder of the
+\fBSELECT\fR
+must refer to this
+FROM
+item as
+f
+not
+foo\&. If an alias is written, a column alias list can also be written to provide substitute names for one or more columns of the table\&.
+.RE
+.PP
+TABLESAMPLE \fIsampling_method\fR ( \fIargument\fR [, \&.\&.\&.] ) [ REPEATABLE ( \fIseed\fR ) ]
+.RS 4
+A
+TABLESAMPLE
+clause after a
+\fItable_name\fR
+indicates that the specified
+\fIsampling_method\fR
+should be used to retrieve a subset of the rows in that table\&. This sampling precedes the application of any other filters such as
+WHERE
+clauses\&. The standard
+PostgreSQL
+distribution includes two sampling methods,
+BERNOULLI
+and
+SYSTEM, and other sampling methods can be installed in the database via extensions\&.
+.sp
+The
+BERNOULLI
+and
+SYSTEM
+sampling methods each accept a single
+\fIargument\fR
+which is the fraction of the table to sample, expressed as a percentage between 0 and 100\&. This argument can be any

+.SS "ORDER BY Clause"
+.PP
+The optional
+ORDER BY
+clause has this general form:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ORDER BY \fIexpression\fR [ ASC | DESC | USING \fIoperator\fR ] [ NULLS { FIRST | LAST } ] [, \&.\&.\&.]
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The
+ORDER BY
+clause causes the result rows to be sorted according to the specified expression(s)\&. If two rows are equal according to the leftmost expression, they are compared according to the next expression and so on\&. If they are equal according to all specified expressions, they are returned in an implementation\-dependent order\&.
+.PP
+Each
+\fIexpression\fR
+can be the name or ordinal number of an output column (\fBSELECT\fR
+list item), or it can be an arbitrary expression formed from input\-column values\&.
+.PP
+The ordinal number refers to the ordinal (left\-to\-right) position of the output column\&. This feature makes it possible to define an ordering on the basis of a column that does not have a unique name\&. This is never absolutely necessary because it is always possible to assign a name to an output column using the
+AS
+clause\&.
+.PP
+It is also possible to use arbitrary expressions in the
+ORDER BY
+clause, including columns that do not appear in the
+\fBSELECT\fR
+output list\&. Thus the following statement is valid:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT name FROM distributors ORDER BY code;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+A limitation of this feature is that an
+ORDER BY
+clause applying to the result of a
+UNION,
+INTERSECT, or
+EXCEPT
+clause can only specify an output column name or number, not an expression\&.
+.PP
+If an
+ORDER BY
+expression is a simple name that matches both an output column name and an input column name,
+ORDER BY
+will interpret it as the output column name\&. This is the opposite of the choice that
+GROUP BY
+will make in the same situation\&. This inconsistency is made to be compatible with the SQL standard\&.
+.PP
+Optionally one can add the key word
+ASC
+(ascending) or
+DESC
+(descending) after any expression in the
+ORDER BY
+clause\&. If not specified,
+ASC
+is assumed by default\&. Alternatively, a specific ordering operator name can be specified in the
+USING
+clause\&. An ordering operator must be a less\-than or greater\-than member of some B\-tree operator family\&.
+ASC
+is usually equivalent to
+USING <
+and
+DESC
+is usually equivalent to
+USING >\&. (But the creator of a user\-defined data type can define exactly what the default sort ordering is, and it might correspond to operators with other names\&.)
+.PP
+If
+NULLS LAST
+is specified, null values sort after all non\-null values; if
+NULLS FIRST
+is specified, null values sort before all non\-null values\&. If neither is specified, the default behavior is
+NULLS LAST
+when
+ASC
+is specified or implied, and
+NULLS FIRST
+when
+DESC
+is specified (thus, the default is to act as though nulls are larger than non\-nulls)\&. When
+USING
+is specified, the default nulls ordering depends on whether the operator is a less\-than or greater\-than operator\&.
+.PP
+Note that ordering options apply only to the expression they follow; for example
+ORDER BY x, y DESC
+does not mean the same thing as
+ORDER BY x DESC, y DESC\&.
+.PP
+Character\-string data is sorted according to the collation that applies to the column being sorted\&. That can be overridden at need by including a
+COLLATE
+clause in the
+\fIexpression\fR, for example
+ORDER BY mycolumn COLLATE "en_US"\&. For more information see
+Section\ \&4.2.10
+and
+Section\ \&24.2\&.
+.SS "LIMIT Clause"
+.PP
+The
+LIMIT
+clause consists of two independent sub\-clauses:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+LIMIT { \fIcount\fR | ALL }
+OFFSET \fIstart\fR
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+The parameter
+\fIcount\fR
+specifies the maximum number of rows to return, while
+\fIstart\fR
+specifies the number of rows to skip before starting to return rows\&. When both are specified,
+\fIstart\fR
+rows are skipped before starting to count the
+\fIcount\fR
+rows to be returned\&.
+.PP
+If the
+\fIcount\fR
+expression evaluates to NULL, it is treated as
+LIMIT ALL, i\&.e\&., no limit\&. If
+\fIstart\fR
+evaluates to NULL, it is treated the same as
+OFFSET 0\&.
+.PP
+SQL:2008 introduced a different syntax to achieve the same result, which
+PostgreSQL
+also supports\&. It is:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+OFFSET \fIstart\fR { ROW | ROWS }
+FETCH { FIRST | NEXT } [ \fIcount\fR ] { ROW | ROWS } { ONLY | WITH TIES }
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+In this syntax, the
+\fIstart\fR
+or
+\fIcount\fR
+value is required by the standard to be a literal constant, a parameter, or a variable name; as a
+PostgreSQL
+extension, other expressions are allowed, but will generally need to be enclosed in parentheses to avoid ambiguity\&. If
+\fIcount\fR
+is omitted in a
+FETCH
+clause, it defaults to 1\&. The
+WITH TIES
+option is used to return any additional rows that tie for the last place in the result set according to the
+ORDER BY
+clause;
+ORDER BY
+is mandatory in this case, and
+SKIP LOCKED
+is not allowed\&.
+ROW
+and
+ROWS
+as well as
+FIRST
+and
+NEXT
+are noise words that don\*(Aqt influence the effects of these clauses\&. According to the standard, the
+OFFSET
+clause must come before the
+FETCH
+clause if both are present; but
+PostgreSQL
+is laxer and allows either order\&.
+.PP
+When using
+LIMIT, it is a good idea to use an
+ORDER BY
+clause that constrains the result rows into a unique order\&. Otherwise you will get an unpredictable subset of the query\*(Aqs rows \(em you might be asking for the tenth through twentieth rows, but tenth through twentieth in what ordering? You don\*(Aqt know what ordering unless you specify
+ORDER BY\&.
+.PP
+The query planner takes
+LIMIT
+into account when generating a query plan, so you are very likely to get different plans (yielding different row orders) depending on what you use for
+LIMIT
+and
+OFFSET\&. Thus, using different
+LIMIT/OFFSET
+values to select different subsets of a query result
+\fIwill give inconsistent results\fR
+unless you enforce a predictable result ordering with
+ORDER BY\&. This is not a bug; it is an inherent consequence of the fact that SQL does not promise to deliver the results of a query in any particular order unless
+ORDER BY
+is used to constrain the order\&.
+.PP
+It is even possible for repeated executions of the same
+LIMIT
+query to return different subsets of the rows of a table, if there is not an
+ORDER BY
+to enforce selection of a deterministic subset\&. Again, this is not a bug; determinism of the results is simply not guaranteed in such a case\&.
+.SS "The Locking Clause"
+.PP
+FOR UPDATE,
+FOR NO KEY UPDATE,
+FOR SHARE
+and
+FOR KEY SHARE
+are
+locking clauses; they affect how
+SELECT
+locks rows as they are obtained from the table\&.
+.PP
+The locking clause has the general form
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+FOR \fIlock_strength\fR [ OF \fItable_name\fR [, \&.\&.\&.] ] [ NOWAIT | SKIP LOCKED ]
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+where
+\fIlock_strength\fR
+can be one of
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+UPDATE
+NO KEY UPDATE
+SHARE
+KEY SHARE
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+For more information on each row\-level lock mode, refer to
+Section\ \&13.3.2\&.
+.PP
+To prevent the operation from waiting for other transactions to commit, use either the
+NOWAIT
+or
+SKIP LOCKED
+option\&. With
+NOWAIT, the statement reports an error, rather than waiting, if a selected row cannot be locked immediately\&. With
+SKIP LOCKED, any selected rows that cannot be immediately locked are skipped\&. Skipping locked rows provides an inconsistent view of the data, so this is not suitable for general purpose work, but can be used to avoid lock contention with multiple consumers accessing a queue\-like table\&. Note that
+NOWAIT
+and
+SKIP LOCKED
+apply only to the row\-level lock(s) \(em the required
+ROW SHARE
+table\-level lock is still taken in the ordinary way (see
+Chapter\ \&13)\&. You can use
+\fBLOCK\fR
+with the
+NOWAIT
+option first, if you need to acquire the table\-level lock without waiting\&.
+.PP
+If specific tables are named in a locking clause, then only rows coming from those tables are locked; any other tables used in the
+\fBSELECT\fR
+are simply read as usual\&. A locking clause without a table list affects all tables used in the statement\&. If a locking clause is applied to a view or sub\-query, it affects all tables used in the view or sub\-query\&. However, these clauses do not apply to
+WITH
+queries referenced by the primary query\&. If you want row locking to occur within a
+WITH
+query, specify a locking clause within the
+WITH
+query\&.
+.PP
+Multiple locking clauses can be written if it is necessary to specify different locking behavior for different tables\&. If the same table is mentioned (or implicitly affected) by more than one locking clause, then it is processed as if it was only specified by the strongest one\&. Similarly, a table is processed as
+NOWAIT
+if that is specified in any of the clauses affecting it\&. Otherwise, it is processed as
+SKIP LOCKED
+if that is specified in any of the clauses affecting it\&.
+.PP
+The locking clauses cannot be used in contexts where returned rows cannot be clearly identified with individual table rows; for example they cannot be used with aggregation\&.
+.PP
+When a locking clause appears at the top level of a
+\fBSELECT\fR
+query, the rows that are locked are exactly those that are returned by the query; in the case of a join query, the rows locked are those that contribute to returned join rows\&. In addition, rows that satisfied the query conditions as of the query snapshot will be locked, although they will not be returned if they were updated after the snapshot and no longer satisfy the query conditions\&. If a
+LIMIT
+is used, locking stops once enough rows have been returned to satisfy the limit (but note that rows skipped over by
+OFFSET
+will get locked)\&. Similarly, if a locking clause is used in a cursor\*(Aqs query, only rows actually fetched or stepped past by the cursor will be locked\&.
+.PP
+When a locking clause appears in a sub\-\fBSELECT\fR, the rows locked are those returned to the outer query by the sub\-query\&. This might involve fewer rows than inspection of the sub\-query alone would suggest, since conditions from the outer query might be used to optimize execution of the sub\-query\&. For example,
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT * FROM (SELECT * FROM mytable FOR UPDATE) ss WHERE col1 = 5;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+will lock only rows having
+col1 = 5, even though that condition is not textually within the sub\-query\&.
+.PP
+Previous releases failed to preserve a lock which is upgraded by a later savepoint\&. For example, this code:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+BEGIN;
+SELECT * FROM mytable WHERE key = 1 FOR UPDATE;
+SAVEPOINT s;
+UPDATE mytable SET \&.\&.\&. WHERE key = 1;
+ROLLBACK TO s;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+would fail to preserve the
+FOR UPDATE
+lock after the
+\fBROLLBACK TO\fR\&. This has been fixed in release 9\&.3\&.
+.if n \{\
+.sp
+.\}

+.br
+.PP
+It is possible for a
+\fBSELECT\fR
+command running at the
+READ COMMITTED
+transaction isolation level and using
+ORDER BY
+and a locking clause to return rows out of order\&. This is because
+ORDER BY
+is applied first\&. The command sorts the result, but might then block trying to obtain a lock on one or more of the rows\&. Once the
+SELECT
+unblocks, some of the ordering column values might have been modified, leading to those rows appearing to be out of order (though they are in order in terms of the original column values)\&. This can be worked around at need by placing the
+FOR UPDATE/SHARE
+clause in a sub\-query, for example
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT * FROM (SELECT * FROM mytable FOR UPDATE) ss ORDER BY column1;
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Note that this will result in locking all rows of
+mytable, whereas
+FOR UPDATE
+at the top level would lock only the actually returned rows\&. This can make for a significant performance difference, particularly if the
+ORDER BY
+is combined with
+LIMIT
+or other restrictions\&. So this technique is recommended only if concurrent updates of the ordering columns are expected and a strictly sorted result is required\&.
+.PP
+At the
+REPEATABLE READ
+or
+SERIALIZABLE
+transaction isolation level this would cause a serialization failure (with an
+SQLSTATE
+of
+\*(Aq40001\*(Aq), so there is no possibility of receiving rows out of order under these isolation levels\&.

+Notice that the

+.SH "COMPATIBILITY"
+.PP
+Of course, the
+\fBSELECT\fR
+statement is compatible with the SQL standard\&. But there are some extensions and some missing features\&.
+.SS "Omitted FROM Clauses"
+.PP
+PostgreSQL
+allows one to omit the
+FROM
+clause\&. It has a straightforward use to compute the results of simple expressions:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT 2+2;
+
+ ?column?
+\-\-\-\-\-\-\-\-\-\-
+        4
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Some other
+SQL
+databases cannot do this except by introducing a dummy one\-row table from which to do the
+\fBSELECT\fR\&.
+.SS "Empty SELECT Lists"
+.PP
+The list of output expressions after
+SELECT
+can be empty, producing a zero\-column result table\&. This is not valid syntax according to the SQL standard\&.
+PostgreSQL
+allows it to be consistent with allowing zero\-column tables\&. However, an empty list is not allowed when
+DISTINCT
+is used\&.
+.SS "Omitting the AS Key Word"
+.PP
+In the SQL standard, the optional key word
+AS
+can be omitted before an output column name whenever the new column name is a valid column name (that is, not the same as any reserved keyword)\&.
+PostgreSQL
+is slightly more restrictive:
+AS
+is required if the new column name matches any keyword at all, reserved or not\&. Recommended practice is to use
+AS
+or double\-quote output column names, to prevent any possible conflict against future keyword additions\&.
+.PP
+In
+FROM
+items, both the standard and
+PostgreSQL
+allow
+AS
+to be omitted before an alias that is an unreserved keyword\&. But this is impractical for output column names, because of syntactic ambiguities\&.
+.SS "ONLY and Inheritance"
+.PP
+The SQL standard requires parentheses around the table name when writing
+ONLY, for example
+SELECT * FROM ONLY (tab1), ONLY (tab2) WHERE \&.\&.\&.\&.
+PostgreSQL
+considers these parentheses to be optional\&.
+.PP
+PostgreSQL
+allows a trailing
+*
+to be written to explicitly specify the non\-ONLY
+behavior of including child tables\&. The standard does not allow this\&.
+.PP
+(These points apply equally to all SQL commands supporting the
+ONLY
+option\&.)
+.SS "TABLESAMPLE Clause Restrictions"
+.PP
+The
+TABLESAMPLE
+clause is currently accepted only on regular tables and materialized views\&. According to the SQL standard it should be possible to apply it to any
+FROM
+item\&.
+.SS "Function Calls in FROM"
+.PP
+PostgreSQL
+allows a function call to be written directly as a member of the
+FROM
+list\&. In the SQL standard it would be necessary to wrap such a function call in a sub\-\fBSELECT\fR; that is, the syntax
+FROM \fIfunc\fR(\&.\&.\&.) \fIalias\fR
+is approximately equivalent to
+FROM LATERAL (SELECT \fIfunc\fR(\&.\&.\&.)) \fIalias\fR\&. Note that
+LATERAL
+is considered to be implicit; this is because the standard requires
+LATERAL
+semantics for an
+UNNEST()
+item in
+FROM\&.
+PostgreSQL
+treats
+UNNEST()
+the same as other set\-returning functions\&.
+.SS "Namespace Available to GROUP BY and ORDER BY"
+.PP
+In the SQL\-92 standard, an
+ORDER BY
+clause can only use output column names or numbers, while a
+GROUP BY
+clause can only use expressions based on input column names\&.
+PostgreSQL
+extends each of these clauses to allow the other choice as well (but it uses the standard\*(Aqs interpretation if there is ambiguity)\&.
+PostgreSQL
+also allows both clauses to specify arbitrary expressions\&. Note that names appearing in an expression will always be taken as input\-column names, not as output\-column names\&.
+.PP
+SQL:1999 and later use a slightly different definition which is not entirely upward compatible with SQL\-92\&. In most cases, however,
+PostgreSQL
+will interpret an
+ORDER BY
+or
+GROUP BY
+expression the same way SQL:1999 does\&.
+.SS "Functional Dependencies"
+.PP
+PostgreSQL
+recognizes functional dependency (allowing columns to be omitted from
+GROUP BY) only when a table\*(Aqs primary key is included in the
+GROUP BY
+list\&. The SQL standard specifies additional conditions that should be recognized\&.
+.SS "LIMIT and OFFSET"
+.PP
+The clauses
+LIMIT
+and
+OFFSET
+are
+PostgreSQL\-specific syntax, also used by
+MySQL\&. The SQL:2008 standard has introduced the clauses
+OFFSET \&.\&.\&. FETCH {FIRST|NEXT} \&.\&.\&.
+for the same functionality, as shown above in
+LIMIT Clause\&. This syntax is also used by
+IBM DB2\&. (Applications written for
+Oracle
+frequently use a workaround involving the automatically generated
+rownum
+column, which is not available in PostgreSQL, to implement the effects of these clauses\&.)
+.SS "FOR NO KEY UPDATE, FOR UPDATE, FOR SHARE, FOR KEY SHARE"
+.PP
+Although
+FOR UPDATE
+appears in the SQL standard, the standard allows it only as an option of
+\fBDECLARE CURSOR\fR\&.
+PostgreSQL
+allows it in any
+\fBSELECT\fR
+query as well as in sub\-\fBSELECT\fRs, but this is an extension\&. The
+FOR NO KEY UPDATE,
+FOR SHARE
+and
+FOR KEY SHARE
+variants, as well as the
+NOWAIT
+and
+SKIP LOCKED
+options, do not appear in the standard\&.
+.SS "Data\-Modifying Statements in WITH"
+.PP
+PostgreSQL
+allows
+\fBINSERT\fR,
+\fBUPDATE\fR, and
+\fBDELETE\fR
+to be used as
+WITH
+queries\&. This is not found in the SQL standard\&.
+.SS "Nonstandard Clauses"
+.PP
+DISTINCT ON ( \&.\&.\&. )
+is an extension of the SQL standard\&.
+.PP
+ROWS FROM( \&.\&.\&. )
+is an extension of the SQL standard\&.
+.PP
+The
+MATERIALIZED
+and
+NOT MATERIALIZED
+options of
+WITH
+are extensions of the SQL standard\&.

+.SH "DESCRIPTION"
+.PP
+\fBSELECT INTO\fR
+creates a new table and fills it with data computed by a query\&. The data is not returned to the client, as it is with a normal
+\fBSELECT\fR\&. The new table\*(Aqs columns have the names and data types associated with the output columns of the
+\fBSELECT\fR\&.
+.SH "PARAMETERS"
+.PP
+TEMPORARY or TEMP
+.RS 4
+If specified, the table is created as a temporary table\&. Refer to
+CREATE TABLE (\fBCREATE_TABLE\fR(7))
+for details\&.
+.RE
+.PP
+UNLOGGED
+.RS 4
+If specified, the table is created as an unlogged table\&. Refer to
+CREATE TABLE (\fBCREATE_TABLE\fR(7))
+for details\&.
+.RE
+.PP
+\fInew_table\fR
+.RS 4
+The name (optionally schema\-qualified) of the table to be created\&.
+.RE
+.PP
+All other parameters are described in detail under
+\fBSELECT\fR(7)\&.
+.SH "NOTES"
+.PP
+\fBCREATE TABLE AS\fR
+is functionally similar to
+\fBSELECT INTO\fR\&.
+\fBCREATE TABLE AS\fR
+is the recommended syntax, since this form of
+\fBSELECT INTO\fR
+is not available in
+ECPG
+or
+PL/pgSQL, because they interpret the
+INTO
+clause differently\&. Furthermore,
+\fBCREATE TABLE AS\fR
+offers a superset of the functionality provided by
+\fBSELECT INTO\fR\&.
+.PP
+In contrast to
+\fBCREATE TABLE AS\fR,
+\fBSELECT INTO\fR
+does not allow specifying properties like a table\*(Aqs access method with
+USING \fImethod\fR
+or the table\*(Aqs tablespace with
+TABLESPACE \fItablespace_name\fR\&. Use
+\fBCREATE TABLE AS\fR
+if necessary\&. Therefore, the default table access method is chosen for the new table\&. See
+default_table_access_method
+for more information\&.
+.SH "EXAMPLES"
+.PP
+Create a new table
+films_recent
+consisting of only recent entries from the table
+films:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+SELECT * INTO films_recent FROM films WHERE date_prod >= \*(Aq2002\-01\-01\*(Aq;
+.fi
+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"
+.PP
+The SQL standard uses
+\fBSELECT INTO\fR
+to represent selecting values into scalar variables of a host program, rather than creating a new table\&. This indeed is the usage found in
+ECPG
+(see
+Chapter\ \&36) and
+PL/pgSQL
+(see
+Chapter\ \&43)\&. The
+PostgreSQL
+usage of
+\fBSELECT INTO\fR
+to represent table creation is historical\&. Some other SQL implementations also use
+\fBSELECT INTO\fR
+in this way (but most SQL implementations support
+\fBCREATE TABLE AS\fR
+instead)\&. Apart from such compatibility considerations, it is best to use
+\fBCREATE TABLE AS\fR
+for this purpose in new code\&.

+.fi
+.SH "DESCRIPTION"
+.PP
+The
+\fBSET\fR
+command changes run\-time configuration parameters\&. Many of the run\-time parameters listed in
+Chapter\ \&20
+can be changed on\-the\-fly with
+\fBSET\fR\&. (Some parameters can only be changed by superusers and users who have been granted
+SET
+privilege on that parameter\&. There are also parameters that cannot be changed after server or session start\&.)
+\fBSET\fR
+only affects the value used by the current session\&.
+.PP
+If
+\fBSET\fR
+(or equivalently
+\fBSET SESSION\fR) is issued within a transaction that is later aborted, the effects of the
+\fBSET\fR
+command disappear when the transaction is rolled back\&. Once the surrounding transaction is committed, the effects will persist until the end of the session, unless overridden by another
+\fBSET\fR\&.
+.PP
+The effects of
+\fBSET LOCAL\fR
+last only till the end of the current transaction, whether committed or not\&. A special case is
+\fBSET\fR
+followed by
+\fBSET LOCAL\fR
+within a single transaction: the
+\fBSET LOCAL\fR
+value will be seen until the end of the transaction, but afterwards (if the transaction is committed) the
+\fBSET\fR
+value will take effect\&.
+.PP
+The effects of
+\fBSET\fR
+or
+\fBSET LOCAL\fR
+are also canceled by rolling back to a savepoint that is earlier than the command\&.
+.PP
+If
+\fBSET LOCAL\fR
+is used within a function that has a
+SET
+option for the same variable (see
+CREATE FUNCTION (\fBCREATE_FUNCTION\fR(7))), the effects of the
+\fBSET LOCAL\fR
+command disappear at function exit; that is, the value in effect when the function was called is restored anyway\&. This allows
+\fBSET LOCAL\fR
+to be used for dynamic or repeated changes of a parameter within a function, while still having the convenience of using the
+SET
+option to save and restore the caller\*(Aqs value\&. However, a regular
+\fBSET\fR
+command overrides any surrounding function\*(Aqs
+SET
+option; its effects will persist unless rolled back\&.

+DEFERRABLE INITIALLY IMMEDIATE, or
+NOT DEFERRABLE\&. The third class is always
+IMMEDIATE
+and is not affected by the
+\fBSET CONSTRAINTS\fR
+command\&. The first two classes start every transaction in the indicated mode, but their behavior can be changed within a transaction by
+\fBSET CONSTRAINTS\fR\&.
+.PP
+\fBSET CONSTRAINTS\fR
+with a list of constraint names changes the mode of just those constraints (which must all be deferrable)\&. Each constraint name can be schema\-qualified\&. The current schema search path is used to find the first matching name if no schema name is specified\&.
+\fBSET CONSTRAINTS ALL\fR
+changes the mode of all deferrable constraints\&.
+.PP
+When
+\fBSET CONSTRAINTS\fR
+changes the mode of a constraint from
+DEFERRED
+to
+IMMEDIATE, the new mode takes effect retroactively: any outstanding data modifications that would have been checked at the end of the transaction are instead checked during the execution of the
+\fBSET CONSTRAINTS\fR
+command\&. If any such constraint is violated, the
+\fBSET CONSTRAINTS\fR
+fails (and does not change the constraint mode)\&. Thus,
+\fBSET CONSTRAINTS\fR
+can be used to force checking of constraints to occur at a specific point in a transaction\&.
+.PP
+Currently, only
+UNIQUE,
+PRIMARY KEY,
+REFERENCES
+(foreign key), and
+EXCLUDE
+constraints are affected by this setting\&.
+NOT NULL
+and
+CHECK
+constraints are always checked immediately when a row is inserted or modified (\fInot\fR
+at the end of the statement)\&. Uniqueness and exclusion constraints that have not been declared
+DEFERRABLE
+are also checked immediately\&.
+.PP
+The firing of triggers that are declared as
+\(lqconstraint triggers\(rq
+is also controlled by this setting \(em they fire at the same time that the associated constraint should be checked\&.
+.SH "NOTES"
+.PP
+Because
+PostgreSQL
+does not require constraint names to be unique within a schema (but only per\-table), it is possible that there is more than one match for a specified constraint name\&. In this case
+\fBSET CONSTRAINTS\fR
+will act on all matches\&. For a non\-schema\-qualified name, once a match or matches have been found in some schema in the search path, schemas appearing later in the path are not searched\&.
+.PP
+This command only alters the behavior of constraints within the current transaction\&. Issuing this outside of a transaction block emits a warning and otherwise has no effect\&.
+.SH "COMPATIBILITY"
+.PP
+This command complies with the behavior defined in the SQL standard, except for the limitation that, in
+PostgreSQL, it does not apply to
+NOT NULL
+and
+CHECK
+constraints\&. Also,
+PostgreSQL
+checks non\-deferrable uniqueness constraints immediately, not at end of statement as the standard would suggest\&.

+.fi
+.SH "DESCRIPTION"
+.PP
+This command sets the current user identifier of the current SQL session to be
+\fIrole_name\fR\&. The role name can be written as either an identifier or a string literal\&. After
+\fBSET ROLE\fR, permissions checking for SQL commands is carried out as though the named role were the one that had logged in originally\&.
+.PP
+The specified
+\fIrole_name\fR
+must be a role that the current session user is a member of\&. (If the session user is a superuser, any role can be selected\&.)
+.PP
+The
+SESSION
+and
+LOCAL
+modifiers act the same as for the regular
+\fBSET\fR
+command\&.
+.PP
+SET ROLE NONE
+sets the current user identifier to the current session user identifier, as returned by
+\fBsession_user\fR\&.
+RESET ROLE
+sets the current user identifier to the connection\-time setting specified by the
+command\-line options,
+\fBALTER ROLE\fR, or
+\fBALTER DATABASE\fR, if any such settings exist\&. Otherwise,
+RESET ROLE
+sets the current user identifier to the current session user identifier\&. These forms can be executed by any user\&.
+.SH "NOTES"
+.PP
+Using this command, it is possible to either add privileges or restrict one\*(Aqs privileges\&. If the session user role has the
+INHERIT
+attribute, then it automatically has all the privileges of every role that it could
+\fBSET ROLE\fR
+to; in this case
+\fBSET ROLE\fR
+effectively drops all the privileges assigned directly to the session user and to the other roles it is a member of, leaving only the privileges available to the named role\&. On the other hand, if the session user role has the
+NOINHERIT
+attribute,
+\fBSET ROLE\fR
+drops the privileges assigned directly to the session user and instead acquires the privileges available to the named role\&.
+.PP
+In particular, when a superuser chooses to
+\fBSET ROLE\fR
+to a non\-superuser role, they lose their superuser privileges\&.
+.PP
+\fBSET ROLE\fR
+has effects comparable to
+\fBSET SESSION AUTHORIZATION\fR, but the privilege checks involved are quite different\&. Also,
+\fBSET SESSION AUTHORIZATION\fR
+determines which roles are allowable for later
+\fBSET ROLE\fR
+commands, whereas changing roles with
+\fBSET ROLE\fR
+does not change the set of roles allowed to a later
+\fBSET ROLE\fR\&.
+.PP
+\fBSET ROLE\fR

+.fi
+.SH "DESCRIPTION"
+.PP
+The
+\fBSET TRANSACTION\fR
+command sets the characteristics of the current transaction\&. It has no effect on any subsequent transactions\&.
+\fBSET SESSION CHARACTERISTICS\fR
+sets the default transaction characteristics for subsequent transactions of a session\&. These defaults can be overridden by
+\fBSET TRANSACTION\fR
+for an individual transaction\&.
+.PP
+The available transaction characteristics are the transaction isolation level, the transaction access mode (read/write or read\-only), and the deferrable mode\&. In addition, a snapshot can be selected, though only for the current transaction, not as a session default\&.
+.PP
+The isolation level of a transaction determines what data the transaction can see when other transactions are running concurrently:
+.PP
+READ COMMITTED
+.RS 4
+A statement can only see rows committed before it began\&. This is the default\&.
+.RE
+.PP
+REPEATABLE READ
+.RS 4
+All statements of the current transaction can only see rows committed before the first query or data\-modification statement was executed in this transaction\&.
+.RE
+.PP
+SERIALIZABLE
+.RS 4
+All statements of the current transaction can only see rows committed before the first query or data\-modification statement was executed in this transaction\&. If a pattern of reads and writes among concurrent serializable transactions would create a situation which could not have occurred for any serial (one\-at\-a\-time) execution of those transactions, one of them will be rolled back with a
+serialization_failure
+error\&.
+.RE
+The SQL standard defines one additional level,
+READ UNCOMMITTED\&. In
+PostgreSQL
+READ UNCOMMITTED
+is treated as
+READ COMMITTED\&.
+.PP
+The transaction isolation level cannot be changed after the first query or data\-modification statement (\fBSELECT\fR,
+\fBINSERT\fR,
+\fBDELETE\fR,
+\fBUPDATE\fR,
+\fBMERGE\fR,
+\fBFETCH\fR, or
+\fBCOPY\fR) of a transaction has been executed\&. See
+Chapter\ \&13
+for more information about transaction isolation and concurrency control\&.
+.PP
+The transaction access mode determines whether the transaction is read/write or read\-only\&. Read/write is the default\&. When a transaction is read\-only, the following SQL commands are disallowed:
+\fBINSERT\fR,
+\fBUPDATE\fR,
+\fBDELETE\fR,
+\fBMERGE\fR, and
+\fBCOPY FROM\fR
+if the table they would write to is not a temporary table; all
+CREATE,
+ALTER, and
+DROP
+commands;
+COMMENT,
+GRANT,
+REVOKE,
+TRUNCATE; and
+EXPLAIN ANALYZE
+and
+EXECUTE
+if the command they would execute is among those listed\&. This is a high\-level notion of read\-only that does not prevent all writes to disk\&.
+.PP
+The
+DEFERRABLE
+transaction property has no effect unless the transaction is also
+SERIALIZABLE
+and
+READ ONLY\&. When all three of these properties are selected for a transaction, the transaction may block when first acquiring its snapshot, after which it is able to run without the normal overhead of a
+SERIALIZABLE
+transaction and without any risk of contributing to or being canceled by a serialization failure\&. This mode is well suited for long\-running reports or backups\&.
+.PP
+The
+SET TRANSACTION SNAPSHOT
+command allows a new transaction to run with the same
+snapshot
+as an existing transaction\&. The pre\-existing transaction must have exported its snapshot with the
+pg_export_snapshot
+function (see
+Section\ \&9.27.5)\&. That function returns a snapshot identifier, which must be given to
+SET TRANSACTION SNAPSHOT
+to specify which snapshot is to be imported\&. The identifier must be written as a string literal in this command, for example
+\*(Aq00000003\-0000001B\-1\*(Aq\&.
+SET TRANSACTION SNAPSHOT
+can only be executed at the start of a transaction, before the first query or data\-modification statement (\fBSELECT\fR,
+\fBINSERT\fR,
+\fBDELETE\fR,
+\fBUPDATE\fR,
+\fBMERGE\fR,
+\fBFETCH\fR, or
+\fBCOPY\fR) of the transaction\&. Furthermore, the transaction must already be set to
+SERIALIZABLE
+or
+REPEATABLE READ
+isolation level (otherwise, the snapshot would be discarded immediately, since
+READ COMMITTED
+mode takes a new snapshot for each command)\&. If the importing transaction uses
+SERIALIZABLE
+isolation level, then the transaction that exported the snapshot must also use that isolation level\&. Also, a non\-read\-only serializable transaction cannot import a snapshot from a read\-only transaction\&.
+.SH "NOTES"
+.PP
+If
+\fBSET TRANSACTION\fR
+is executed without a prior
+\fBSTART TRANSACTION\fR
+or
+\fBBEGIN\fR, it emits a warning and otherwise has no effect\&.
+.PP
+It is possible to dispense with
+\fBSET TRANSACTION\fR
+by instead specifying the desired
+\fItransaction_modes\fR
+in
+\fBBEGIN\fR
+or
+\fBSTART TRANSACTION\fR\&. But that option is not available for
+\fBSET TRANSACTION SNAPSHOT\fR\&.
+.PP
+The session default transaction modes can also be set or examined via the configuration parameters
+default_transaction_isolation,
+default_transaction_read_only, and
+default_transaction_deferrable\&. (In fact
+\fBSET SESSION CHARACTERISTICS\fR
+is just a verbose equivalent for setting these variables with
+\fBSET\fR\&.) This means the defaults can be set in the configuration file, via
+\fBALTER DATABASE\fR, etc\&. Consult
+Chapter\ \&20
+for more information\&.
+.PP
+The current transaction\*(Aqs modes can similarly be set or examined via the configuration parameters
+transaction_isolation,
+transaction_read_only, and
+transaction_deferrable\&. Setting one of these parameters acts the same as the corresponding
+\fBSET TRANSACTION\fR
+option, with the same restrictions on when it can be done\&. However, these parameters cannot be set in the configuration file, or from any source other than live SQL\&.
+.SH "EXAMPLES"
+.PP
+To begin a new transaction with the same snapshot as an already existing transaction, first export the snapshot from the existing transaction\&. That will return the snapshot identifier, for example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+BEGIN TRANSACTION ISOLATION LEVEL REPEATABLE READ;
+SELECT pg_export_snapshot();
+ pg_export_snapshot
+\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
+ 00000003\-0000001B\-1
+(1 row)
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+Then give the snapshot identifier in a
+\fBSET TRANSACTION SNAPSHOT\fR
+command at the beginning of the newly opened transaction:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+BEGIN TRANSACTION ISOLATION LEVEL REPEATABLE READ;
+SET TRANSACTION SNAPSHOT \*(Aq00000003\-0000001B\-1\*(Aq;
+.fi
+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"
+.PP
+These commands are defined in the
+SQL
+standard, except for the
+DEFERRABLE
+transaction mode and the
+\fBSET TRANSACTION SNAPSHOT\fR
+form, which are
+PostgreSQL
+extensions\&.
+.PP
+SERIALIZABLE
+is the default transaction isolation level in the standard\&. In
+PostgreSQL
+the default is ordinarily
+READ COMMITTED, but you can change it as mentioned above\&.
+.PP
+In the SQL standard, there is one other transaction characteristic that can be set with these commands: the size of the diagnostics area\&. This concept is specific to embedded SQL, and therefore is not implemented in the
+PostgreSQL
+server\&.
+.PP
+The SQL standard requires commas between successive
+\fItransaction_modes\fR, but for historical reasons
+PostgreSQL
+allows the commas to be omitted\&.

+.nf
+TRUNCATE [ TABLE ] [ ONLY ] \fIname\fR [ * ] [, \&.\&.\&. ]
+    [ RESTART IDENTITY | CONTINUE IDENTITY ] [ CASCADE | RESTRICT ]
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBTRUNCATE\fR
+quickly removes all rows from a set of tables\&. It has the same effect as an unqualified
+\fBDELETE\fR
+on each table, but since it does not actually scan the tables it is faster\&. Furthermore, it reclaims disk space immediately, rather than requiring a subsequent
+\fBVACUUM\fR
+operation\&. This is most useful on large tables\&.
+.SH "PARAMETERS"
+.PP
+\fIname\fR
+.RS 4
+The name (optionally schema\-qualified) of a table to truncate\&. If
+ONLY
+is specified before the table name, only that table is truncated\&. If
+ONLY
+is not specified, the table and all its descendant tables (if any) are truncated\&. Optionally,
+*
+can be specified after the table name to explicitly indicate that descendant tables are included\&.
+.RE
+.PP
+RESTART IDENTITY
+.RS 4
+Automatically restart sequences owned by columns of the truncated table(s)\&.
+.RE
+.PP
+CONTINUE IDENTITY
+.RS 4
+Do not change the values of sequences\&. This is the default\&.
+.RE
+.PP
+CASCADE
+.RS 4
+Automatically truncate all tables that have foreign\-key references to any of the named tables, or to any tables added to the group due to
+CASCADE\&.
+.RE
+.PP
+RESTRICT
+.RS 4
+Refuse to truncate if any of the tables have foreign\-key references from tables that are not listed in the command\&. This is the default\&.
+.RE
+.SH "NOTES"
+.PP
+You must have the
+TRUNCATE
+privilege on a table to truncate it\&.
+.PP
+\fBTRUNCATE\fR
+acquires an
+ACCESS EXCLUSIVE
+lock on each table it operates on, which blocks all other concurrent operations on the table\&. When
+RESTART IDENTITY
+is specified, any sequences that are to be restarted are likewise locked exclusively\&. If concurrent access to a table is required, then the
+\fBDELETE\fR
+command should be used instead\&.
+.PP
+\fBTRUNCATE\fR
+cannot be used on a table that has foreign\-key references from other tables, unless all such tables are also truncated in the same command\&. Checking validity in such cases would require table scans, and the whole point is not to do one\&. The
+CASCADE
+option can be used to automatically include all dependent tables \(em but be very careful when using this option, or else you might lose data you did not intend to! Note in particular that when the table to be truncated is a partition, siblings partitions are left untouched, but cascading occurs to all referencing tables and all their partitions with no distinction\&.
+.PP
+\fBTRUNCATE\fR
+will not fire any
+ON DELETE
+triggers that might exist for the tables\&. But it will fire
+ON TRUNCATE
+triggers\&. If
+ON TRUNCATE
+triggers are defined for any of the tables, then all
+BEFORE TRUNCATE
+triggers are fired before any truncation happens, and all
+AFTER TRUNCATE
+triggers are fired after the last truncation is performed and any sequences are reset\&. The triggers will fire in the order that the tables are to be processed (first those listed in the command, and then any that were added due to cascading)\&.
+.PP
+\fBTRUNCATE\fR
+is not MVCC\-safe\&. After truncation, the table will appear empty to concurrent transactions, if they are using a snapshot taken before the truncation occurred\&. See
+Section\ \&13.6
+for more details\&.
+.PP
+\fBTRUNCATE\fR
+is transaction\-safe with respect to the data in the tables: the truncation will be safely rolled back if the surrounding transaction does not commit\&.
+.PP
+When
+RESTART IDENTITY
+is specified, the implied
+\fBALTER SEQUENCE RESTART\fR
+operations are also done transactionally; that is, they will be rolled back if the surrounding transaction does not commit\&. Be aware that if any additional sequence operations are done on the restarted sequences before the transaction rolls back, the effects of these operations on the sequences will be rolled back, but not their effects on
+\fBcurrval()\fR; that is, after the transaction
+\fBcurrval()\fR
+will continue to reflect the last sequence value obtained inside the failed transaction, even though the sequence itself may no longer be consistent with that\&. This is similar to the usual behavior of
+\fBcurrval()\fR
+after a failed transaction\&.
+.PP
+\fBTRUNCATE\fR
+can be used for foreign tables if supported by the foreign data wrapper, for instance, see
+postgres_fdw\&.
+.SH "EXAMPLES"
+.PP
+Truncate the tables
+bigtable
+and
+fattable:
+.sp
+.if n \{\

+.nf
+TRUNCATE othertable CASCADE;
+.fi
+.if n \{\
+.RE
+.\}
+.SH "COMPATIBILITY"
+.PP
+The SQL:2008 standard includes a
+\fBTRUNCATE\fR
+command with the syntax
+TRUNCATE TABLE \fItablename\fR\&. The clauses
+CONTINUE IDENTITY/RESTART IDENTITY
+also appear in that standard, but have slightly different though related meanings\&. Some of the concurrency behavior of this command is left implementation\-defined by the standard, so the above notes should be considered and compared with other implementations if necessary\&.

+.sp
+The

+is the number of rows updated, including matched rows whose values did not change\&. Note that the number may be less than the number of rows that matched the
+\fIcondition\fR
+when updates were suppressed by a
+BEFORE UPDATE
+trigger\&. If
+\fIcount\fR
+is 0, no rows were updated by the query (this is not considered an error)\&.
+.PP
+If the
+\fBUPDATE\fR
+command contains a
+RETURNING
+clause, the result will be similar to that of a
+\fBSELECT\fR
+statement containing the columns and values defined in the
+RETURNING
+list, computed over the row(s) updated by the command\&.
+.SH "NOTES"
+.PP
+When a
+FROM
+clause is present, what essentially happens is that the target table is joined to the tables mentioned in the
+\fIfrom_item\fR
+list, and each output row of the join represents an update operation for the target table\&. When using
+FROM
+you should ensure that the join produces at most one output row for each row to be modified\&. In other words, a target row shouldn\*(Aqt join to more than one row from the other table(s)\&. If it does, then only one of the join rows will be used to update the target row, but which one will be used is not readily predictable\&.
+.PP
+Because of this indeterminacy, referencing other tables only within sub\-selects is safer, though often harder to read and slower than using a join\&.
+.PP
+In the case of a partitioned table, updating a row might cause it to no longer satisfy the partition constraint of the containing partition\&. In that case, if there is some other partition in the partition tree for which this row satisfies its partition constraint, then the row is moved to that partition\&. If there is no such partition, an error will occur\&. Behind the scenes, the row movement is actually a
+\fBDELETE\fR
+and
+\fBINSERT\fR
+operation\&.
+.PP
+There is a possibility that a concurrent
+\fBUPDATE\fR
+or
+\fBDELETE\fR
+on the row being moved will get a serialization failure error\&. Suppose session 1 is performing an
+\fBUPDATE\fR
+on a partition key, and meanwhile a concurrent session 2 for which this row is visible performs an
+\fBUPDATE\fR
+or
+\fBDELETE\fR
+operation on this row\&. In such case, session 2\*(Aqs
+\fBUPDATE\fR
+or
+\fBDELETE\fR
+will detect the row movement and raise a serialization failure error (which always returns with an SQLSTATE code \*(Aq40001\*(Aq)\&. Applications may wish to retry the transaction if this occurs\&. In the usual case where the table is not partitioned, or where there is no row movement, session 2 would have identified the newly updated row and carried out the
+\fBUPDATE\fR/\fBDELETE\fR
+on this new row version\&.
+.PP
+Note that while rows can be moved from local partitions to a foreign\-table partition (provided the foreign data wrapper supports tuple routing), they cannot be moved from a foreign\-table partition to another partition\&.
+.PP
+An attempt of moving a row from one partition to another will fail if a foreign key is found to directly reference an ancestor of the source partition that is not the same as the ancestor that\*(Aqs mentioned in the

+.SH "DESCRIPTION"
+.PP
+\fBVACUUM\fR
+reclaims storage occupied by dead tuples\&. In normal
+PostgreSQL
+operation, tuples that are deleted or obsoleted by an update are not physically removed from their table; they remain present until a
+\fBVACUUM\fR
+is done\&. Therefore it\*(Aqs necessary to do
+\fBVACUUM\fR
+periodically, especially on frequently\-updated tables\&.
+.PP
+Without a
+\fItable_and_columns\fR
+list,
+\fBVACUUM\fR
+processes every table and materialized view in the current database that the current user has permission to vacuum\&. With a list,
+\fBVACUUM\fR
+processes only those table(s)\&.
+.PP
+\fBVACUUM ANALYZE\fR
+performs a
+\fBVACUUM\fR
+and then an
+\fBANALYZE\fR
+for each selected table\&. This is a handy combination form for routine maintenance scripts\&. See
+\fBANALYZE\fR(7)
+for more details about its processing\&.
+.PP
+Plain
+\fBVACUUM\fR
+(without
+FULL) simply reclaims space and makes it available for re\-use\&. This form of the command can operate in parallel with normal reading and writing of the table, as an exclusive lock is not obtained\&. However, extra space is not returned to the operating system (in most cases); it\*(Aqs just kept available for re\-use within the same table\&. It also allows us to leverage multiple CPUs in order to process indexes\&. This feature is known as
+parallel vacuum\&. To disable this feature, one can use
+PARALLEL
+option and specify parallel workers as zero\&.
+\fBVACUUM FULL\fR
+rewrites the entire contents of the table into a new disk file with no extra space, allowing unused space to be returned to the operating system\&. This form is much slower and requires an
+ACCESS EXCLUSIVE
+lock on each table while it is being processed\&.
+.PP
+When the option list is surrounded by parentheses, the options can be written in any order\&. Without parentheses, options must be specified in exactly the order shown above\&. The parenthesized syntax was added in
+PostgreSQL
+9\&.0; the unparenthesized syntax is deprecated\&.
+.SH "PARAMETERS"
+.PP
+FULL
+.RS 4
+Selects
+\(lqfull\(rq
+vacuum, which can reclaim more space, but takes much longer and exclusively locks the table\&. This method also requires extra disk space, since it writes a new copy of the table and doesn\*(Aqt release the old copy until the operation is complete\&. Usually this should only be used when a significant amount of space needs to be reclaimed from within the table\&.
+.RE
+.PP
+FREEZE
+.RS 4
+Selects aggressive
+\(lqfreezing\(rq
+of tuples\&. Specifying
+FREEZE
+is equivalent to performing
+\fBVACUUM\fR
+with the
+vacuum_freeze_min_age
+and
+vacuum_freeze_table_age
+parameters set to zero\&. Aggressive freezing is always performed when the table is rewritten, so this option is redundant when
+FULL
+is specified\&.
+.RE
+.PP
+VERBOSE
+.RS 4
+Prints a detailed vacuum activity report for each table\&.
+.RE
+.PP
+ANALYZE
+.RS 4
+Updates statistics used by the planner to determine the most efficient way to execute a query\&.
+.RE
+.PP
+DISABLE_PAGE_SKIPPING
+.RS 4
+Normally,
+\fBVACUUM\fR
+will skip pages based on the
+visibility map\&. Pages where all tuples are known to be frozen can always be skipped, and those where all tuples are known to be visible to all transactions may be skipped except when performing an aggressive vacuum\&. Furthermore, except when performing an aggressive vacuum, some pages may be skipped in order to avoid waiting for other sessions to finish using them\&. This option disables all page\-skipping behavior, and is intended to be used only when the contents of the visibility map are suspect, which should happen only if there is a hardware or software issue causing database corruption\&.
+.RE
+.PP
+SKIP_LOCKED
+.RS 4
+Specifies that
+\fBVACUUM\fR
+should not wait for any conflicting locks to be released when beginning work on a relation: if a relation cannot be locked immediately without waiting, the relation is skipped\&. Note that even with this option,
+\fBVACUUM\fR
+may still block when opening the relation\*(Aqs indexes\&. Additionally,
+\fBVACUUM ANALYZE\fR
+may still block when acquiring sample rows from partitions, table inheritance children, and some types of foreign tables\&. Also, while
+\fBVACUUM\fR
+ordinarily processes all partitions of specified partitioned tables, this option will cause
+\fBVACUUM\fR
+to skip all partitions if there is a conflicting lock on the partitioned table\&.
+.RE
+.PP
+INDEX_CLEANUP
+.RS 4
+Normally,
+\fBVACUUM\fR
+will skip index vacuuming when there are very few dead tuples in the table\&. The cost of processing all of the table\*(Aqs indexes is expected to greatly exceed the benefit of removing dead index tuples when this happens\&. This option can be used to force
+\fBVACUUM\fR
+to process indexes when there are more than zero dead tuples\&. The default is
+AUTO, which allows
+\fBVACUUM\fR
+to skip index vacuuming when appropriate\&. If
+INDEX_CLEANUP
+is set to
+ON,
+\fBVACUUM\fR
+will conservatively remove all dead tuples from indexes\&. This may be useful for backwards compatibility with earlier releases of
+PostgreSQL
+where this was the standard behavior\&.
+.sp
+INDEX_CLEANUP
+can also be set to
+OFF
+to force
+\fBVACUUM\fR
+to
+\fIalways\fR
+skip index vacuuming, even when there are many dead tuples in the table\&. This may be useful when it is necessary to make
+\fBVACUUM\fR
+run as quickly as possible to avoid imminent transaction ID wraparound (see
+Section\ \&25.1.5)\&. However, the wraparound failsafe mechanism controlled by
+vacuum_failsafe_age
+will generally trigger automatically to avoid transaction ID wraparound failure, and should be preferred\&. If index cleanup is not performed regularly, performance may suffer, because as the table is modified indexes will accumulate dead tuples and the table itself will accumulate dead line pointers that cannot be removed until index cleanup is completed\&.
+.sp
+This option has no effect for tables that have no index and is ignored if the
+FULL
+option is used\&. It also has no effect on the transaction ID wraparound failsafe mechanism\&. When triggered it will skip index vacuuming, even when
+INDEX_CLEANUP
+is set to
+ON\&.
+.RE
+.PP
+PROCESS_TOAST
+.RS 4
+Specifies that
+\fBVACUUM\fR
+should attempt to process the corresponding
+TOAST
+table for each relation, if one exists\&. This is usually the desired behavior and is the default\&. Setting this option to false may be useful when it is only necessary to vacuum the main relation\&. This option is required when the
+FULL
+option is used\&.
+.RE
+.PP
+TRUNCATE
+.RS 4
+Specifies that
+\fBVACUUM\fR
+should attempt to truncate off any empty pages at the end of the table and allow the disk space for the truncated pages to be returned to the operating system\&. This is normally the desired behavior and is the default unless the
+vacuum_truncate
+option has been set to false for the table to be vacuumed\&. Setting this option to false may be useful to avoid
+ACCESS EXCLUSIVE
+lock on the table that the truncation requires\&. This option is ignored if the
+FULL
+option is used\&.
+.RE
+.PP
+PARALLEL
+.RS 4
+Perform index vacuum and index cleanup phases of
+\fBVACUUM\fR
+in parallel using
+\fIinteger\fR
+background workers (for the details of each vacuum phase, please refer to
+Table\ \&28.41)\&. The number of workers used to perform the operation is equal to the number of indexes on the relation that support parallel vacuum which is limited by the number of workers specified with
+PARALLEL
+option if any which is further limited by
+max_parallel_maintenance_workers\&. An index can participate in parallel vacuum if and only if the size of the index is more than
+min_parallel_index_scan_size\&. Please note that it is not guaranteed that the number of parallel workers specified in
+\fIinteger\fR
+will be used during execution\&. It is possible for a vacuum to run with fewer workers than specified, or even with no workers at all\&. Only one worker can be used per index\&. So parallel workers are launched only when there are at least
+2
+indexes in the table\&. Workers for vacuum are launched before the start of each phase and exit at the end of the phase\&. These behaviors might change in a future release\&. This option can\*(Aqt be used with the
+FULL
+option\&.
+.RE
+.PP
+\fIboolean\fR
+.RS 4
+Specifies whether the selected option should be turned on or off\&. You can write
+TRUE,
+ON, or
+1
+to enable the option, and
+FALSE,
+OFF, or
+0
+to disable it\&. The
+\fIboolean\fR
+value can also be omitted, in which case
+TRUE
+is assumed\&.
+.RE
+.PP
+\fIinteger\fR
+.RS 4
+Specifies a non\-negative integer value passed to the selected option\&.
+.RE
+.PP
+\fItable_name\fR
+.RS 4
+The name (optionally schema\-qualified) of a specific table or materialized view to vacuum\&. If the specified table is a partitioned table, all of its leaf partitions are vacuumed\&.
+.RE
+.PP
+\fIcolumn_name\fR
+.RS 4
+The name of a specific column to analyze\&. Defaults to all columns\&. If a column list is specified,
+ANALYZE
+must also be specified\&.
+.RE
+.SH "OUTPUTS"
+.PP
+When
+VERBOSE
+is specified,
+\fBVACUUM\fR
+emits progress messages to indicate which table is currently being processed\&. Various statistics about the tables are printed as well\&.
+.SH "NOTES"
+.PP
+To vacuum a table, one must ordinarily be the table\*(Aqs owner or a superuser\&. However, database owners are allowed to vacuum all tables in their databases, except shared catalogs\&. (The restriction for shared catalogs means that a true database\-wide
+\fBVACUUM\fR
+can only be performed by a superuser\&.)
+\fBVACUUM\fR
+will skip over any tables that the calling user does not have permission to vacuum\&.
+.PP
+\fBVACUUM\fR
+cannot be executed inside a transaction block\&.
+.PP
+For tables with
+GIN
+indexes,
+\fBVACUUM\fR
+(in any form) also completes any pending index insertions, by moving pending index entries to the appropriate places in the main
+GIN
+index structure\&. See
+Section\ \&70.4.1
+for details\&.
+.PP
+We recommend that all databases be vacuumed regularly in order to remove dead rows\&.
+PostgreSQL
+includes an
+\(lqautovacuum\(rq
+facility which can automate routine vacuum maintenance\&. For more information about automatic and manual vacuuming, see
+Section\ \&25.1\&.
+.PP
+The
+\fBFULL\fR
+option is not recommended for routine use, but might be useful in special cases\&. An example is when you have deleted or updated most of the rows in a table and would like the table to physically shrink to occupy less disk space and allow faster table scans\&.
+\fBVACUUM FULL\fR
+will usually shrink the table more than a plain
+\fBVACUUM\fR
+would\&.
+.PP
+The
+\fBPARALLEL\fR
+option is used only for vacuum purposes\&. If this option is specified with the
+\fBANALYZE\fR
+option, it does not affect
+\fBANALYZE\fR\&.
+.PP
+\fBVACUUM\fR
+causes a substantial increase in I/O traffic, which might cause poor performance for other active sessions\&. Therefore, it is sometimes advisable to use the cost\-based vacuum delay feature\&. For parallel vacuum, each worker sleeps in proportion to the work done by that worker\&. See
+Section\ \&20.4.4
+for details\&.
+.PP
+Each backend running
+\fBVACUUM\fR
+without the
+FULL
+option will report its progress in the
+pg_stat_progress_vacuum
+view\&. Backends running
+\fBVACUUM FULL\fR
+will instead report their progress in the
+pg_stat_progress_cluster
+view\&. See
+Section\ \&28.4.3
+and
+Section\ \&28.4.4
