Yeah, we could consider the views a transitional thing, and get rid of
them after a release or two.  Tell people to change over to either look
in the pg_sequence catalog, or use the information_schema view.  Does
that view expose everything that there is, though, or will we have
proprietary extensions that are not in SQL2003?
