Probably DROP ROLE for global users too.

We've been asked quite often for a not-quite-superuser, as in, one which
can bypass the normal GRANT-based permission system but which can't do
things like create untrusted functions or do other particularly bad
activities. I can certainly see value in that. Another oft-requested
option is a read-only role which pg_dump or an auditor could use.
Anyway, this is getting a bit far afield from the original discussion,
which looked like it might actually be heading somewhere interesting..
