Since we now include a sample line for replication on local
connections in pg_hba.conf, don't include it where local
connections aren't available (such as on win32).
Also make sure we use authmethodlocal and not authmethod on
the sample line.
host all all ::1/128 @authmethod@
# Allow replication connections from localhost, by a user with the
# replication privilege.
