Ah.  That would work better than what I thought you were suggesting, but
I still don't trust it a whole lot --- there's the problem of "universal
binaries" (PPC & PPC64 & Intel) for instance, which I believe some
people have managed to build Postgres as.

Agreed.  Also we could have it today if we base it off inspection of
pg_control_version.
