Re: Postgresql performance and tuning questions

Our philosophy is to use products that have been established, tested and
stable. We tend to not go with newer versions until they have time to
mature and have the bugs worked out. This is the version of the DB that
was packaged with the version of Linux we're using. So our thinking is
that we will go with that until we learn better. Our experience is more
with mainframes where habitually we proceed methodically. (That
translates to: slower than what we see with open source.)

Is there an impelling reason why we should migrate to a newer version
before we begin to use, observe, and experience Postgres of our own?

Thanks, Bob

Why are you not starting with a reasonably up-to-date version of
Postgres?
