Ugh.  We could fix pg_dump to output the commands in a better order,
but that won't help for dumps from existing releases.

Given that rbt is the owner of the object, I'm not sure that it is
sensible to interpret the above as revoking his ability to grant
privileges to others.  Seems to me that his ability to GRANT is inherent
in being the owner, and as such his "grant option" bits are irrelevant.
So maybe the commands are okay and the backend's interpretation is
bogus.

Peter, any thoughts?
