I believe the pty problem has been fixed in Panther/Darwin 7.0 (unless
someone can tell me otherwise).

If behavior differs in terminal and GUI mode, perhaps it is useful to
check environment variable settings passed to `psql' that are different
in the two cases (value of process-environment).  Also you may want to
check what arguments are used when psql is called (by stopping at
start-process (?)) in both cases.
