Tom Lane 27a54ae282 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.		2002-04-17 20:57:57 +00:00
