Howdy. Quick chump patch: if libpq finds a ~/.pgpass but can't stat
it, print something to stderr letting the user know. If someone went
out of their way to put a .pgpass file in place, if they can't read
it, it seems worth while to alert them to the fact that it's not being
used (ex: root creates a .pgpass file but forgets to chown it).
