There is no effective difference between reindexing databases via this utility and via other methods for accessing the server\&. +.SH "OPTIONS" +.PP +reindexdb +accepts the following command\-line arguments: +.PP +\fB\-a\fR +.br +\fB\-\-all\fR +.RS 4 +Reindex all databases\&. +.RE +.PP +\fB\-\-concurrently\fR +.RS 4 +Use the +CONCURRENTLY +option\&.

If this is not specified, the database name is read from the environment variable +\fBPGDATABASE\fR\&. If that is not set, the user name specified for the connection is used\&. The +\fIdbname\fR +can be a +connection string\&. If so, connection string parameters will override any conflicting command line options\&. +.RE +.PP +\fB\-e\fR +.br +\fB\-\-echo\fR +.RS 4 +Echo the commands that +reindexdb +generates and sends to the server\&. +.RE +.PP +\fB\-i \fR\fB\fIindex\fR\fR +.br +\fB\-\-index=\fR\fB\fIindex\fR\fR +.RS 4 +Recreate +\fIindex\fR +only\&. Multiple indexes can be recreated by writing multiple +\fB\-i\fR +switches\&. +.RE +.PP +\fB\-j \fR\fB\fInjobs\fR\fR +.br +\fB\-\-jobs=\fR\fB\fInjobs\fR\fR +.RS 4 +Execute the reindex commands in parallel by running +\fInjobs\fR +commands simultaneously\&. This option may reduce the processing time but it also increases the load on the database server\&. +.sp +reindexdb +will open +\fInjobs\fR +connections to the database, so make sure your +max_connections +setting is high enough to accommodate all connections\&. +.sp +Note that this option is incompatible with the +\fB\-\-index\fR +and +\fB\-\-system\fR +options\&. +.RE +.PP +\fB\-q\fR +.br +\fB\-\-quiet\fR +.RS 4 +Do not display progress messages\&. +.RE +.PP +\fB\-s\fR +.br +\fB\-\-system\fR +.RS 4 +Reindex database\*(Aqs system catalogs only\&. +.RE +.PP +\fB\-S \fR\fB\fIschema\fR\fR +.br +\fB\-\-schema=\fR\fB\fIschema\fR\fR +.RS 4 +Reindex +\fIschema\fR +only\&.

Multiple tables can be reindexed by writing multiple +\fB\-t\fR +switches\&. +.RE +.PP +\fB\-\-tablespace=\fR\fB\fItablespace\fR\fR +.RS 4 +Specifies the tablespace where indexes are rebuilt\&.

If the value begins with a slash, it is used as the directory for the Unix domain socket\&. +.RE +.PP +\fB\-p \fR\fB\fIport\fR\fR +.br +\fB\-\-port=\fR\fB\fIport\fR\fR +.RS 4 +Specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections\&. +.RE +.PP +\fB\-U \fR\fB\fIusername\fR\fR +.br +\fB\-\-username=\fR\fB\fIusername\fR\fR +.RS 4 +User name to connect as\&. +.RE +.PP +\fB\-w\fR +.br +\fB\-\-no\-password\fR +.RS 4 +Never issue a password prompt\&. If the server requires password authentication and a password is not available by other means such as a +\&.pgpass +file, the connection attempt will fail\&. This option can be useful in batch jobs and scripts where no user is present to enter a password\&. +.RE +.PP +\fB\-W\fR +.br +\fB\-\-password\fR +.RS 4 +Force +reindexdb +to prompt for a password before connecting to a database\&. +.sp +This option is never essential, since +reindexdb +will automatically prompt for a password if the server demands password authentication\&. However, +reindexdb +will waste a connection attempt finding out that the server wants a password\&. In some cases it is worth typing +\fB\-W\fR +to avoid the extra connection attempt\&. +.RE +.PP +\fB\-\-maintenance\-db=\fR\fB\fIdbname\fR\fR +.RS 4 +Specifies the name of the database to connect to to discover which databases should be reindexed, when +\fB\-a\fR/\fB\-\-all\fR +is used\&. If not specified, the +postgres +database will be used, or if that does not exist, +template1 +will be used\&. This can be a +connection string\&. If so, connection string parameters will override any conflicting command line options\&. Also, connection string parameters other than the database name itself will be re\-used when connecting to other databases\&. +.RE +.SH "ENVIRONMENT" +.PP +\fBPGDATABASE\fR +.br +\fBPGHOST\fR +.br +\fBPGPORT\fR +.br +\fBPGUSER\fR +.RS 4 +Default connection parameters +.RE +.PP +\fBPG_COLOR\fR +.RS 4 +Specifies whether to use color in diagnostic messages\&.

The database server must be running at the targeted host\&. Also, any default connection settings and environment variables used by the +libpq +front\-end library will apply\&. +.SH "NOTES" +.PP +reindexdb +might need to connect several times to the +PostgreSQL +server, asking for a password each time\&. It is convenient to have a +~/\&.pgpass +file in such cases\&.
