I agree a more general fix is needed, but I think excluding temp
tables as suggested is a good idea for performance, independently of
permissions concerns.  vacuum_rel() will ignore requests to vacuum
such tables, which is why we've not heard complaints before, but
nonetheless we're wasting server round trips by issuing those
requests.
