So, the backpatch down to 12 is straight-forward, with some conflicts
in ./configure. ~12 handles also differently its CFLAGS with
pg_config.h.win32. 11 is more annoying because it lacks
HAVE_SYS_PROCCTL_H and it would need a partial backport of f98b847. I
am not completely sure if this could have more side effects, though,
even if the part of pmsignal.c is left out. It should not..
At the end, I have just done this stuff down to ~12, 11 does not seem
worth the trouble as the next stable version to go out of support.
I'll reduce gokiburi's script a bit, as a result, until the oldest
version support is v12.
