Well, as it is, it looks like the failure of getcwd() might be an
incidental problem, and the inability to find postgres was what sunk
the ship.  In fact, the inability to find postgres is an entirely
illusory problem created by the failure of getcwd().  If you just got
one error message saying "getcwd failed", I think it would be more
clear what the problem was.  I had to go read the code to figure out
that the failure of getcwd() would result in a guaranteed failure to
find the postgres executable.
