Cleanups don't go to back-branches.

Yes, we should use that instead:

Windows is known for keeping things backward compatible, so I don't
see any reason to not allow Postgres to run on those versions.
Outdated of course, still they could be used at runtime even if they
cannot compile the code.

Let's tackle that as a separate patch as this is MSVC-dependent.

Right, per the change for src/common/exec.c. I am wondering though if
we don't have more portability issues if we try to run Postgres on
something older than XP as there has been many changes in the last
couple of years, and we have no more buildfarm members that old.
Anyway, that's not worth the cost. For now I have applied to the tree
the smaller version as that's still a good cut.
