Are you sure? If we remove a type, then its oid becomes up for grabs by
the unused_oids script.
We have removed a few functions in 7.4 (oidsrand, etc.) and I wouldn't
be surprised if we haven't _already_ reused those oids...
I think the core should mandate it as policy never to reuse oids and
perhaps make the unused_oids script "remember" what has been used...
