But we currently don't allow to drop. Which is confusingly
inconsistent. And allowing object creation withing pg_catalog only from
within extension scripts and not from normal SQL sounds like a *very*
poor workaround giving problems to quite some people upgrading from
earlier releases. Especially from those where we didn't have extensions.

And I don't see why allowing consistent relation creation/removal from
pg_catalog is conflicting with fixing the issue at hand?
