[PATCH] Prevent hanging on unreachable hosts on startup - Mailing list pgsql-bugs

The signal handler installed by setup_cancel_handler() will ignore
attempts to exit psql should a host be unreachable. Since the
functionality it provides won't be used until later, it doesn't make
sense to set it up so early. Therefore, move the signal handler closer
to where it is first needed.
