I think you can just remove the join with pg_namespace and the associated
where clauses (the nspname one and the join condition one).  I'm not
sure if there'll be any other problems since I don't currently have a
7.1.x system to try against.

And, for good measure, if you're running 7.1.x, you should really upgrade
soon. ;)
