However, while you might be able to sit on an old libpq for awhile,
I don't think you could get away with not updating pg_dump for every
new server release. It would be better not to try to port pg_dump at
all than to distribute an obsolete one. psql is better, but not all
that much better :-( as both describe.c and tab-complete.c are pretty
dependent on the server version.
