The hard part would be reimplementing the Pl/PgSQL stored procedures
we require, as well as fixing any postgresql-specific dialect
problems.  Plus a few places (in the installer and such) that we check
for PostgreSQL-specific things.

My guess would be it's still another 4 or 5 man-months to make it all
work properly (which is why we haven't gotten there yet... Especially
since there isn't a strong need to move off PostgreSQL, it's a great
and powerful OZ^H^Hdatabase.)
