[ADMIN] where would I find the files I need?

Hi everybody,

I am running postgres 8.3.0 on linux (hardware is dell).
When I issue: cat /etc/redhat-release
It comes back with: Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
and when I issue: uname -r
It says: 2.6.9-42.ELsmp

Given that, would somebody please tell me where I can go
to grab the correct set of files to upgrade to the latest
postgres, v8.3.3?

I have been to the postgres website and via File Browser, I got to:
Top → binary → v8.3.3 → linux → rpms → redhat → rhel-4-x86_64

Am I at the right place?
Please advise.

Many thanks.
