But do we really care about people who put 7.5 initdb.exe in the same
directory as, say, 7.6 postgres.exe?

Exactly my point. The mismatches occur because we *think* we know the right
path under *nix, and so we grab the version string to make certain. Under
win32, there would be no such ambiguity, except if people mix versions in
the same directory; which certainly doesn't appear worth the cost to protect
against.

Ok; please allow me to continue to respectfully disagree that this is
justified :-)
