Thanks, I'll put a patch together. Sorry -- IIRC, both of those
features are probably too new for me to have used, regardless of what
we decide is the minimum version for 18.

As for picking a version... 3.6 will have been EOL for almost three
years by the time 18 releases. It seems like we would drop it happily,
were it not for RHEL8. But RHEL also supports side-by-side Python,
right? In general, I'd be more than willing to try plumbing that
through the new tests, if it lets us drop end-of-life versions for new
code.

(I don't know if we'll need to drop 3.6 for PG18, specifically, but I
also think we shouldn't plan to support 3.6 for the full RHEL8
lifetime.)

Thanks,
