Don't include local line on platforms without support
Don't include local line on platforms without support

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.
