I think it'd be a good idea to add some more discoverability: what would
be deleted if an object X were to be deleted? I suppose this is just a
recursive query on pg_depend, but expecting users to handle that on
their own is preposterous. We could offer a simple function, to which
you pass classid, objid, objsubid, returns setof same plus obj_description.
