The GRANT statement can now specify WITH INHERIT TRUE or WITH INHERIT FALSE to control whether the member inherits the granted role's permissions. For symmetry, you can now likewise write WITH ADMIN TRUE or WITH ADMIN FALSE to turn ADMIN OPTION on or off. If a GRANT does not specify WITH INHERIT, the behavior based on whether the member role is marked INHERIT or NOINHERIT. This means that if all roles are marked INHERIT or NOINHERIT before any role grants are performed, the behavior is identical to what we had before; otherwise, it's different, because ALTER ROLE [NO]INHERIT now only changes the default behavior of future grants, and has no effect on existing ones. Patch by me. Reviewed and testing by Nathan Bossart and Tushar Ahuja, with design-level comments from various others.
