Thanks for the fast response!

The hardware was the same of the previous, but I'm not sure about
Ubuntu version.
As I got the whole old server backup, I know that the Postgres version
is 8.2 by looking at the PGVERSION file. Not sure if it is 8.2.5, but
I imagined that it wouldn't make much difference.

I installed the postgres via apt-get, and the installation structure
was the same of the previous one. I even tried to copy the whole
Postgres installation from the backup, but when I try to start the
server with the postgres command, I receive an error from the OS
saying it was impossible to execute the binaries. Now I'm thinking
that a 64bit version was installed.

I'll try to investigate this a little further and keep up with you.

Thanks for the help!
