Re: Postgresql performance and tuning questions

I do understand your school of thinking. But let me say this, from just
a user point of view who had used 7.4.x, 8.0, and 8.1, I'd highly
recommend to start off with 8.1. I can comment on performance in
particular among other great stuff such as scalability, robustness etc.
The performance in 8.1 compared with previous releases (even 8.0) is
remarkable and frankly like the difference between day and light,
specially when it comes to complex queries in large databases.  From a
technical point of view, you can view the docs to find out more about
the great improvements with 8.1, such as
http://www.postgresql.org/docs/whatsnew

Just my two cents  :)

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?
