REVOKE bypasser FROM anon failed with Expected: a privilege keyword, found: bypasser, since REVOKE only knew the privilege form. PostgreSQL revokes a role membership by naming the role without a keyword (REVOKE).

The statement now parses into a new Statement::RevokeRole with GRANTED BY and CASCADE or RESTRICT. It goes through the same privilege-first fallback as the role membership GRANT, so existing statements and their errors are unchanged.
