Yes. Works just fine. You might end up with some fun with
applications finding the client libraries (generally better
to let them all find the new libraries, even when you're
expecting them to talk to the older server, I think) but
apart from that running different versions on different
ports seems to just work.
If you use some sort of binary package to install, rather
than installing from source all bets are off, and it likely
won't work, but that's just a packaging limitation.
