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 :-()
