I think you are trying to use a 7.0 or older pg_dump against a 7.1 or
newer database. Or maybe it was 7.2 where we changed the layout of
pg_aggregate. Anyway, this is a version skew problem.
(Newer versions of pg_dump do complain if the server version isn't one
they recognize, btw. But you are invoking an old one :-()
