No support has been dropped at the source level, so any PG version ought to work there. But you might have to build it yourself --- which versions are available in binary form from prebuilt repositories is a very different question. I'd try grabbing the SRPM for whichever version you want and seeing if it doesn't build on your machine. Building from SRPMs is not hard, and it's a good skill to acquire if you're using non-mainstream hardware. regards, tom lane
