It looks like your PR got raced by mine earlier in the week. I think this one is OK, though, after a rebase on master. However, I would keep the Python 2.7 variant on the ports that had it becuase it is very challenging for any users on Python 2 to get off of it. It is a much more practical experience for them to get off of Python 2 when they do a major PostgreSQL update.

🆗 I've reversed the python27 changes - they were only present in 13 & 14
