ALTER POLICY
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. Note that ALTER POLICY only allows modifying the set of roles that the policy applies to, and the USING and WITH CHECK expressions. To change other attributes of the policy, such as:
the commands it applies to, or whether it is permissive or restrictive, you must drop and recreate the policy.
To use ALTER POLICY, you must own the table that the policy applies to.
In the second form of ALTER POLICY, if the role list, using_expression, and check_expression are specified, they are replaced independently. When one of these clauses is omitted, the corresponding part of the policy is not changed.

new_name

role_name
The role(s) to which the policy applies. Multiple roles can be specified at once. To apply the policy to all roles, use PUBLIC.
using_expression
The USING expression for the policy. See CREATE POLICY for details.
check_expression
The WITH CHECK expression for the policy. See CREATE POLICY for details.
