Give them separate install directories, separate data directories, and
different port numbers, and you're good to go. All of the principal PG
developers run multiple versions on the same machine. (The machine I'm
typing this on has 7.0, 7.1, 7.2, 7.3, 7.4, 8.0, and 8.1beta postmasters
alive right now...)
