Don't connect() to a wildcard address in test_postmaster_connection().
At least OpenBSD, NetBSD, and Windows don't support it. This repairs
pg_ctl for listen_addresses='0.0.0.0' and listen_addresses='::'. Since
pg_ctl prefers to test a Unix-domain socket, Windows users are most
likely to need this change. Back-patch to 9.1 (all supported versions).
This could change pg_ctl interaction with loopback-interface firewall
rules. Therefore, in 9.4 and earlier (released branches), activate the
change only on known-affected platforms.
Reported (bug #13611) and designed by Kondo Yuta.
