Hello, I have two postgresql servers 9.1.5 and 8.4.8 running on ubuntu machine, both are fresh installs and both has the same configuration files and databases.
I am running queries sequentially on each machine using a database dumped from a life server , and 9.1 server is much slower than 8.4. I am wondering what might be the cause for this behaviour? Does 9.1 requires more attention on setting some parameters .. ? Regards
