NAME

       ALTER_POLICY - change the definition of a row level security policy

SYNOPSIS

       ALTER POLICY name ON table_name RENAME TO new_name

       ALTER POLICY name ON table_name
           [ TO { role_name | PUBLIC | CURRENT_USER | SESSION_USER } [, ...] ]
           [ USING ( using_expression ) ]
           [ WITH CHECK ( check_expression ) ]

DESCRIPTION

       ALTER POLICY changes the definition of an existing row-level security policy.

       To use ALTER POLICY, you must own the table that the policy applies to.

       In the second form of ALTER POLICY, the role list, using_expression, and check_expression
       are replaced independently if specified. When one of those clauses is omitted, the
       corresponding part of the policy is unchanged.

PARAMETERS

       name
           The name of an existing policy to alter.

       table_name
           The name (optionally schema-qualified) of the table that the policy is on.

       new_name
           The new name for the policy.

       role_name
           The role(s) to which the policy applies. Multiple roles can be specified at one time.
           To apply the policy to all roles, use PUBLIC.

       using_expression
           The USING expression for the policy. See CREATE POLICY (CREATE_POLICY(7)) for details.

       check_expression
           The WITH CHECK expression for the policy. See CREATE POLICY (CREATE_POLICY(7)) for
           details.
