I am using Dell Hardware on Redhat Enterprise
Linux and wanting to go from 8.2.4 to 8.3.0.
Would you please tell me where I might find
documentation/references to run multiple versions
of postgreSQL on one OS?

I don't think this is particularly critical for 8.2 to 8.3, but in cases
where you're trying to jump multiple major versions in one step, it's
often the case that it will go smoother with the later pg_dump.

If your platform doesn't make it easy to have two versions installed
concurrently, one simple way to do this is to install the newer PG code
on another machine and do the dump across the network.
