I'll second that. It isn't just "the open source nature" of PostgreSQL
which will keep it viable, it is the active developer and user community
which has grown up around it which makes it unlikely that it will become
irrelevant. Other db efforts may try to get the open source gloss with
licensing and tarballs, but PostgreSQL actually has the process and
*people* which makes it successful.
