From 6198420ad8a72e37f4fe4964616b17e0fd33b808 Mon Sep 17 00:00:00 2001 From: Joe Conway Date: Mon, 28 Mar 2022 15:10:04 -0400 Subject: Use has_privs_for_roles for predefined role checks Generally if a role is granted membership to another role with NOINHERIT they must use SET ROLE to access the privileges of that role, however with predefined roles the membership and privilege is conflated. Fix that by replacing is_member_of_role with has_privs_for_role for predefined roles. Patch does not remove is_member_of_role from acl.h, but it does add a warning not to use that function for privilege checking. Not backpatched based on hackers list discussion.
