Ramiro,
Yes, this will pose no problem. We do it commonly. You can simply install your v9.0 server, as Szymon has suggested, on another port to effect your testing. Be sure you've set up a 9.0-compatible cluster of course; you can't share data.

Where can we found a paper for helping us? Our platform is Centos 5.4 x86 64 bits -- Ramiro Barreca [email protected] I think there is no paper on that, that's just too simple. Install another database, run it on another port (that needs changing one value in the postgresql.conf). regards Szymon
