Hm, but with this you're trading that problem for "is the right version
of pg_config in my PATH?". I can't see using this in TAP testing, for
instance, because it would never work in "make check" scenarios.
This idea might well be useful for external packages which are always
built/tested against installed versions of Postgres. But it seems like
we need to think harder about what to do for our own usages, and that
may lead to a different solution altogether.
