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.
