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.

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.
