FYI, Linux isn't an OS, it's a kernel.

With RedHat, you'll either need to build your own RPMs from source
where each goes to a different directory etc OR compile from source
using a different --prefix and then use separate startup scripts that
set LD_LIBRARY_PATH and PATH etc... for each install on startup.

If you're running Debian, you can install >1 version of pgsql side by
side. Not sure how it's done exactly, but I've heard it repeated
enough to believe it's true.
