And fail entirely for the other 10%? Not good enough if so :-( ... the
idea is to make install easier not harder. How much code would it take
to emulate as much of "which" as we need, do you think? What's our
fallback position if it doesn't work?

After thinking about it for a while, I think that there shouldn't be any
dependency on USER, period. initdb (and anything else that cares) ought
to get the name of the user they are executing as, and use that. I
can't see any good reason why the name inserted into the databases
should be potentially different from the ownership of the files.
Is 'whoami' a portable way of getting the current user id, or not?
The only reference I have about portable shell programming says that
the POSIX-approved command for this is 'id -u -n', and that 'whoami'
is a BSD-ism. I've got doubts that either one is universal ... we might
have to try both. Grumble.
