Interactive things like pg often use /dev/tty as stdout.  I was once
frustrated for days by code that behaved like this.  It turns out that
the it explicitly opened /dev/tty, but reported the error cryptically
as `can't open stdout' or some such.  Anyway, the fix was to chmod 666
/dev/tty.  I suspect that one was overlooked in the repair attempt.
