SYNOPSIS
ALTER POLICY \nname\n ON \ntable_name\n RENAME TO \nnew_name\n
ALTER POLICY \nname\n ON \ntable_name\n
\n
[ TO { \nrole_name\n | PUBLIC | CURRENT_ROLE | CURRENT_USER | SESSION_USER } [, ...] ]
\n
[ USING ( \nusing_expression\n ) ]
\n
[ WITH CHECK ( \ncheck_expression\n ) ]DESCRIPTION
ALTER POLICY changes the definition of an existing row-level security policy. Note that ALTER POLICY only allows the set of roles to which the policy applies and the USING and WITH CHECK expressions to be modified. To change other properties of a policy, such as the command to which it applies or whether it is permissive or restrictive, the policy must be dropped and recreated.
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.
