Opclasses live in namespaces. I also took the opportunity to create

an 'opclass owner' column in pg_opclass.  Nothing is done with it at
present, but since there are plans to invent a CREATE OPERATOR CLASS
command soon, we'll probably want DROP OPERATOR CLASS too, which
suggests that a notion of ownership would be a good idea.
