This discussion stalled.  I think we should do *something* for 
PostgreSQL 15.

I suspect at this point, the Meson move isn't going to happen for 
PostgreSQL 15.  Even if the code were ready, which it is not, then this 
kind of thing would surely be something more sensible to put into PG16 
early rather than PG15 late.  So I'm setting aside any concerns about 
which Python 3.x is the appropriate minimum level.

There is the discussion [0], which involves raising the minimum Python 
version from 2.6 to 2.7, which would affect some build farm members. 
But if we're going to drop 2.x anyway for PG15, say, then we don't need 
to spend time organizing a 2.6 to 2.7 transition.  (Although 
backpatching might be required.)

Also, I was recently doing some bug fixing work in PL/Python, and just 
getting a Python 2 installation is not straightforward these days on the 
sort of OS that might be on a development machine.  So there is also 
that driver for dropping Python 2.

I think what I wrote in the message I'm responding to is the best way 
forward, although maybe with less than 60 days now.

Thoughts?
