Log message:
    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.
