Slightly older versions, which do work to build postgres with the proposed
patchset, run on python3 3.5. I don't think it's likely we could make the
versions that only required 3.4 work reasonably.


Is RHEL7 really an issue? I only have Centos 7 around, but that has python
3.6.

I don't know much about AIX, but according to https://repology.org/project/python/versions
the AIX toolbox has 3.7.11. I don't know enough about AIX to know whether
there's other sources of python3, bison, etc that are common. On the AIX
system I have access to they all seem to be symlinked to /opt/freeware, which
I understand is that toolbox stuff?

Greetings,

Andres Freund
