CREATE POLICY <em class="replaceable"><code>name</code></em> ON <em class="replaceable"><code>table_name</code></em>
    [ AS { PERMISSIVE | RESTRICTIVE } ]
    [ FOR { ALL | SELECT | INSERT | UPDATE | DELETE } ]
    [ TO { <em class="replaceable"><code>role_name</code></em> | PUBLIC | CURRENT_ROLE | CURRENT_USER | SESSION_USER } [, ...] ]
    [ USING ( <em class="replaceable"><code>using_expression</code></em> ) ]
    [ WITH CHECK ( <em class="replaceable"><code>check_expression</code></em> ) ]
</pre></div><div class="refsect1" id="id-1.9.3.75.5"><h2>Description</h2><p>
   The <code class="command">CREATE POLICY</code> command defines a new row-level
   security policy for a table.  Note that row-level security must be
   enabled on the table (using <code class="command">ALTER TABLE ... ENABLE ROW LEVEL
   SECURITY</code>) in order for created policies to be applied.
  </p><p>
   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 <code class="literal">USING</code>,
   while new rows that would be created via <code class="literal">INSERT</code>
   or <code class="literal">UPDATE</code> are checked against the expression specified
   in <code class="literal">WITH CHECK</code>.  When a <code class="literal">USING</code>
   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 <code class="literal">WITH CHECK</code> expression returns true for a row
   then that row is inserted or updated, while if false or null is returned
   then an error occurs.
  </p><p>
   For <code class="command">INSERT</code>, <code class="command">UPDATE</code>, and
   <code class="command">MERGE</code> statements,
   <code class="literal">WITH CHECK</code> expressions are enforced after
   <code class="literal">BEFORE</code> triggers are fired, and before any actual data
   modifications are made.  Thus a <code class="literal">BEFORE ROW</code> trigger may
   modify the data to be inserted, affecting the result of the security
   policy check.  <code class="literal">WITH CHECK</code> expressions are enforced
   before any other constraints.
  </p><p>
   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.
  </p><p>
   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.
   <a class="xref" href="sql-createpolicy.html#SQL-CREATEPOLICY-SUMMARY" title="Table 287. Policies Applied by Command Type">Table 287</a> summarizes how the different types
   of policy apply to specific commands.
  </p><p>
   For policies that can have both <code class="literal">USING</code>
   and <code class="literal">WITH CHECK</code> expressions (<code class="literal">ALL</code>
   and <code class="literal">UPDATE</code>), if no <code class="literal">WITH CHECK</code>
   expression is defined, then the <code class="literal">USING</code> expression will be
   used both to determine which rows are visible (normal
   <code class="literal">USING</code> case) and which new rows will be allowed to be
   added (<code class="literal">WITH CHECK</code> case).
  </p><p>
   If row-level security is enabled for a table, but no applicable policies
   exist, a <span class="quote"><span class="quote">default deny</span></span> policy is assumed, so that no rows will
   be visible or updatable.
  </p></div><div class="refsect1" id="id-1.9.3.75.6"><h2>Parameters</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>name</code></em></span></dt><dd><p>
      The name of the policy to be created.  This must be distinct from the
      name of any other policy for the table.
     </p></dd><dt><span class="term"><em class="replaceable"><code>table_name</code></em></span></dt><dd><p>
      The name (optionally schema-qualified) of the table the
      policy applies to.
     </p></dd><dt><span class="term"><code class="literal">PERMISSIVE</code></span></dt><dd><p>
      Specify that the policy is to be created as a permissive policy.
      All permissive policies which are applicable to a given query will
      be combined together using the Boolean <span class="quote"><span class="quote">OR</span></span> operator.  By creating
      permissive policies, administrators can add to the set of records
      which can be accessed.  Policies are permissive by default.
     </p></dd><dt><span class="term"><code class="literal">RESTRICTIVE</code></span></dt><dd><p>
      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 <span class="quote"><span class="quote">AND</span></span> operator.  By creating
      restrictive policies, administrators can reduce the set of records
      which can be accessed as all restrictive policies must be passed for
      each record.
     </p><p>
      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.
     </p></dd><dt><span class="term"><em class="replaceable"><code>command</code></em></span></dt><dd><p>
      The command to which the policy applies.  Valid options are
      <code class="command">ALL</code>, <code class="command">SELECT</code>,
      <code class="command">INSERT</code>, <code class="command">UPDATE</code>,
      and <code class="command">DELETE</code>.
      <code class="command">ALL</code> is the default.
      See below for specifics regarding how these are applied.
     </p></dd><dt><span class="term"><em class="replaceable"><code>role_name</code></em></span></dt><dd><p>
      The role(s) to which the policy is to be applied.  The default is

      to queries that refer to the table if row-level security is enabled.
      Rows for which the expression returns true will be visible.  Any
      rows for which the expression returns false or null will not be
      visible to the user (in a <code class="command">SELECT</code>), and will not be
      available for modification (in an <code class="command">UPDATE</code>

      Any <acronym class="acronym">SQL</acronym> conditional expression (returning

     </p></dd></dl></div><div class="refsect2" id="id-1.9.3.75.6.3"><h3>Per-Command Policies</h3><div class="variablelist"><dl class="variablelist"><dt id="SQL-CREATEPOLICY-ALL"><span class="term"><code class="literal">ALL</code></span></dt><dd><p>
         Using <code class="literal">ALL</code> for a policy means that it will apply
         to all commands, regardless of the type of command.  If an
         <code class="literal">ALL</code> policy exists and more specific policies
         exist, then both the <code class="literal">ALL</code> policy and the more
         specific policy (or policies) will be applied.
         Additionally, <code class="literal">ALL</code> policies will be applied to
         both the selection side of a query and the modification side, using
         the <code class="literal">USING</code> expression for both cases if only
         a <code class="literal">USING</code> expression has been defined.
       </p><p>
         As an example, if an <code class="literal">UPDATE</code> is issued, then the
         <code class="literal">ALL</code> policy will be applicable both to what the
         <code class="literal">UPDATE</code> will be able to select as rows to be
         updated (applying the <code class="literal">USING</code> expression),
         and to the resulting updated rows, to check if they are permitted
         to be added to the table (applying the <code class="literal">WITH CHECK</code>
         expression, if defined, and the <code class="literal">USING</code> expression
         otherwise).  If an <code class="command">INSERT</code>
         or <code class="command">UPDATE</code> command attempts to add rows to the
         table that do not pass the <code class="literal">ALL</code>
         policy's <code class="literal">WITH CHECK</code> expression, the entire
         command will be aborted.
       </p></dd><dt id="SQL-CREATEPOLICY-SELECT"><span class="term"><code class="literal">SELECT</code></span></dt><dd><p>
         Using <code class="literal">SELECT</code> for a policy means that it will apply
         to <code class="literal">SELECT</code> queries and whenever
         <code class="literal">SELECT</code> permissions are required on the relation the
         policy is defined for.  The result is that only those records from the
         relation that pass the <code class="literal">SELECT</code> policy will be
         returned during a <code class="literal">SELECT</code> query, and that queries
         that require <code class="literal">SELECT</code> permissions, such as
         <code class="literal">UPDATE</code>, will also only see those records
         that are allowed by the <code class="literal">SELECT</code> policy.
         A <code class="literal">SELECT</code> policy cannot have a <code class="literal">WITH
         CHECK</code> expression, as it only applies in cases where
         records are being retrieved from the relation.
       </p></dd><dt id="SQL-CREATEPOLICY-INSERT"><span class="term"><code class="literal">INSERT</code></span></dt><dd><p>
         Using <code class="literal">INSERT</code> for a policy means that it will apply
         to <code class="literal">INSERT</code> commands and <code class="literal">MERGE</code>
         commands that contain <code class="literal">INSERT</code> actions.
         Rows being inserted that do
         not pass this policy will result in a policy violation error, and the
         entire <code class="literal">INSERT</code> command will be aborted.
         An <code class="literal">INSERT</code> policy cannot have
         a <code class="literal">USING</code> expression, as it only applies in cases
         where records are being added to the relation.
       </p><p>
         Note that <code class="literal">INSERT</code> with <code class="literal">ON CONFLICT DO
         UPDATE</code> checks <code class="literal">INSERT</code> policies'
         <code class="literal">WITH CHECK</code> expressions only for rows appended
         to the relation by the <code class="literal">INSERT</code> path.
       </p></dd><dt id="SQL-CREATEPOLICY-UPDATE"><span class="term"><code class="literal">UPDATE</code></span></dt><dd><p>
         Using <code class="literal">UPDATE</code> for a policy means that it will apply
         to <code class="literal">UPDATE</code>, <code class="literal">SELECT FOR UPDATE</code>
         and <code class="literal">SELECT FOR SHARE</code> commands, as well as
         auxiliary <code class="literal">ON CONFLICT DO UPDATE</code> clauses of
         <code class="literal">INSERT</code> commands.
         <code class="literal">MERGE</code> commands containing <code class="literal">UPDATE</code>
         actions are affected as well.  Since <code class="literal">UPDATE</code>
         involves pulling an existing record and replacing it with a new
         modified record, <code class="literal">UPDATE</code>
         policies accept both a <code class="literal">USING</code> expression and
         a <code class="literal">WITH CHECK</code> expression.
         The <code class="literal">USING</code> expression determines which records
         the <code class="literal">UPDATE</code> command will see to operate against,
         while the <code class="literal">WITH CHECK</code> expression defines which
         modified rows are allowed to be stored back into the relation.
       </p><p>
         Any rows whose updated values do not pass the
         <code class="literal">WITH CHECK</code> expression will cause an error, and the
         entire command will be aborted.  If only a <code class="literal">USING</code>
         clause is specified, then that clause will be used for both
         <code class="literal">USING</code> and <code class="literal">WITH CHECK</code> cases.
       </p><p>
         Typically an <code class="literal">UPDATE</code> command also needs to read
         data from columns in the relation being updated (e.g., in a
         <code class="literal">WHERE</code> clause or a <code class="literal">RETURNING</code>
         clause, or in an expression on the right hand side of the
         <code class="literal">SET</code> clause).  In this case,
         <code class="literal">SELECT</code> rights are also required on the relation
         being updated, and the appropriate <code class="literal">SELECT</code> or
         <code class="literal">ALL</code> policies will be applied in addition to
         the <code class="literal">UPDATE</code> policies.  Thus the user must have
         access to the row(s) being updated through a <code class="literal">SELECT</code>
         or <code class="literal">ALL</code> policy in addition to being granted
         permission to update the row(s) via an <code class="literal">UPDATE</code>
         or <code class="literal">ALL</code> policy.
       </p><p>
         When an <code class="literal">INSERT</code> command has an auxiliary
         <code class="literal">ON CONFLICT DO UPDATE</code> clause, if the
         <code class="literal">UPDATE</code> path is taken, the row to be updated is
         first checked against the <code class="literal">USING</code> expressions of
         any <code class="literal">UPDATE</code> policies, and then the new updated row
         is checked against the <code class="literal">WITH CHECK</code> expressions.
         Note, however, that unlike a standalone <code class="literal">UPDATE</code>
         command, if the existing row does not pass the
         <code class="literal">USING</code> expressions, an error will be thrown (the
         <code class="literal">UPDATE</code> path will <span class="emphasis"><em>never</em></span> be silently
         avoided).
       </p></dd><dt id="SQL-CREATEPOLICY-DELETE"><span class="term"><code class="literal">DELETE</code></span></dt><dd><p>
         Using <code class="literal">DELETE</code> for a policy means that it will apply
         to <code class="literal">DELETE</code> commands.  Only rows that pass this
         policy will be seen by a <code class="literal">DELETE</code> command.  There can
         be rows that are visible through a <code class="literal">SELECT</code> that are
         not available for deletion, if they do not pass the
         <code class="literal">USING</code> expression for
         the <code class="literal">DELETE</code> policy.
       </p><p>
         In most cases a <code class="literal">DELETE</code> command also needs to read
         data from columns in the relation that it is deleting from (e.g.,
         in a <code class="literal">WHERE</code> clause or a
         <code class="literal">RETURNING</code> clause). In this case,
         <code class="literal">SELECT</code> rights are also required on the relation,
         and the appropriate <code class="literal">SELECT</code> or
         <code class="literal">ALL</code> policies will be applied in addition to
         the <code class="literal">DELETE</code> policies.  Thus the user must have
         access to the row(s) being deleted through a <code class="literal">SELECT</code>
         or <code class="literal">ALL</code> policy in addition to being granted
         permission to delete the row(s) via a <code class="literal">DELETE</code> or
         <code class="literal">ALL</code> policy.
       </p><p>

    When multiple policies of different command types apply to the same command
    (for example, <code class="literal">SELECT</code> and <code class="literal">UPDATE</code>
    policies applied to an <code class="literal">UPDATE</code> command), then the user
    must have both types of permissions (for example, permission to select rows
    from the relation as well as permission to update them).  Thus the
    expressions for one type of policy are combined with the expressions for
    the other type of policy using the <code class="literal">AND</code> operator.
   </p><p>
    When multiple policies of the same command type apply to the same command,
    then there must be at least one <code class="literal">PERMISSIVE</code> policy
    granting access to the relation, and all of the
    <code class="literal">RESTRICTIVE</code> policies must pass.  Thus all the
    <code class="literal">PERMISSIVE</code> policy expressions are combined using
    <code class="literal">OR</code>, all the <code class="literal">RESTRICTIVE</code> policy
    expressions are combined using <code class="literal">AND</code>, and the results are
    combined using <code class="literal">AND</code>.  If there are no
    <code class="literal">PERMISSIVE</code> policies, then access is denied.
   </p><p>
    Note that, for the purposes of combining multiple policies,
    <code class="literal">ALL</code> policies are treated as having the same type as
    whichever other type of policy is being applied.
   </p><p>
    For example, in an <code class="literal">UPDATE</code> command requiring both
    <code class="literal">SELECT</code> and <code class="literal">UPDATE</code> permissions, if
    there are multiple applicable policies of each type, they will be combined
    as follows:

</p><pre class="programlisting">
<em class="replaceable"><code>expression</code></em> from RESTRICTIVE SELECT/ALL policy 1
AND
<em class="replaceable"><code>expression</code></em> from RESTRICTIVE SELECT/ALL policy 2
AND

AND
(
  <em class="replaceable"><code>expression</code></em> from PERMISSIVE SELECT/ALL policy 1
  OR

</pre></div></div><div class="refsect1" id="id-1.9.3.75.7"><h2>Notes</h2><p>
   You must be the owner of a table to create or change policies for it.
  </p><p>
   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.
  </p><p>
   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 <code class="literal">LEAKPROOF</code> may be evaluated before
   policy expressions, as they are assumed to be trustworthy.
  </p><p>
   Since policy expressions
   are added to the user's 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's rights and any policies which apply to the view owner, except if
   the view is defined using the <code class="literal">security_invoker</code> option
   (see <a class="link" href="sql-createview.html" title="CREATE VIEW"><code class="command">CREATE VIEW</code></a>).
  </p><p>
   No separate policy exists for <code class="command">MERGE</code>. Instead, the policies
   defined for <code class="command">SELECT</code>, <code class="command">INSERT</code>,
   <code class="command">UPDATE</code>, and <code class="command">DELETE</code> are applied
   while executing <code class="command">MERGE</code>, depending on the actions that are
   performed.
