After further thought I started wondering why I hadn't back-patched this.
It's certainly safe/trivial enough for back-patching. If we leave it just
in HEAD, then extension authors wouldn't be able to use it in the intended
way until 9.5 is old enough that they don't care about supporting 9.5.x
anymore; which is perhaps 5 years away. If we back-patch all supported
branches then it would be safe to rely on VERSION_NUM for building
extensions within a year or two.
Any objections to doing that?
