Hi,

The last release of python2 was 2.7.18 released 2020-04-20, with support
already having ended before that 2020-01-01.

To me it seems time to drop plpython2 support. Supporting plpython2
until ~7 years after python2 is EOL is already quite long... It'd be one
thing if it were completely painless, but imo it's not.

I was about to list better plpython2/3 support (including the regex
replacements for the regress tests) as a TODO for the meson proposal,
but it doesn't really seem worth investing in that...

Greetings,

Andres Freund
