That's an interesting question. I'm not sure if we'd want to disable
the no-root check on the Unix side, but it might make sense to. But
this has no bearing on what libpq does, does it?

No. There is no reason at all for libpq to think it is part of a
postgres-supplied program, so it can't use any relative-path tricks,
even if it had the program's argv[0] which it does not. Either the
compiled-in path works, or the user has to give one.

(But having said that, if Windows provides a way for a DLL to find
out its own filesystem location, maybe relative path from there would
work.)
