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?

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