Alas, inside pg_ctl, there is this comment:
# FIXME: This is horribly misconceived.
# 1) If password authentication is set up, the connection will fail.
# 2) If a virtual host is set up, the connection may fail.
# 3) If network traffic filters are set up tight enough, the connection
# may fail.
# 4) When no Unix domain sockets are available, the connection will
# fail. (Using TCP/IP by default ain't better.)
# 5) When a different port is configured, the connection will fail
# or go to the wrong server.
# 6) If the dynamic loader is not set up correctly (for this user/at
# this time), psql will fail (to find libpq).
# 7) If psql is misconfigured, this may fail.
Feel free to send in a patch. :-)
