I'll take a look there. According to Meson, the following versions had
Python version bumps:

0.61.5: 3.6
0.56.2: 3.5
0.45.1: 3.4

Taking a look at pkgs.org, Debian 10, Ubuntu 20.04, and Oracle Linux
7 (a RHEL re-spin), and CentOS 7, all have >= Python 3.6.8. Granted,
this isn't the whole picture of what Postgres supports from version 16+.
To put things in perspective, Python 3.6 was released on December 23,
2016, which is coming up on 7 years. Python 3.6 reached end of life on
the same date in 2021.

Is there a complete list somewhere that talks about what platforms each
version of Postgres supports?
