I'm not so sure that was a great idea to begin with. If you create a private schema with a SECURITY DEFINER function in it, it's a bit odd to allow someone with pg_read_all_data to execute it. Granted, that's documented behavior, but I'm not sure the privileges should be bundled in that fashion. > > It might be reasonable to give implicit USAGE privileges on all > > schemas > > during maintenance commands to pg_maintain roles. That's an even more specific exception: having USAGE only in the context of a maintenance command. I think that's a new concept, right? Regards, Jeff Davis
