For those who provided some guidance, I say "thank you." You comments helped out a lot. All of our customers who are using the older release are now very pleased with the performance of the database now that we were able to give them meaningful configuration settings. I'm also pleased to se

Thanks for the link. I'll look into those. I'm going only on what my engineers are telling me, but they say upgrading breaks a lot of source code with some SQL commands that are a pain to hunt down and kill. Not sure if that's true, but that's what I'm told. Todd On Jun 16, 2005, at 10:0

We run the RPM's for RH 7.3 on our 7.2 install base with no problems. RPM's as recent as for PostgreSQL 7.4.2 are available here: ftp://ftp10.us.postgresql.org/pub/postgresql/binary/v7.4.2/redhat/redhat-7.3/ Or you can always compile from source. There isn't any such thing as a 'supported' packag

Yes, it is 7.2. Why? because an older version of our software runs on RH7.3 and that was the latest supported release of Postgresql for RH7.3 (that we can find). We're currently ported to 8, but we still have a large installed base with the other version. On Jun 15, 2005, at 7:18 AM, Tom L

I deeply apologize if this has been covered with some similar topic before, but I need a little guidance in the optimization department. We use Postgres as our database and we're having some issues dealing with customers who are, shall we say, "thrifty" when it comes to buying RAM. We tel
