I think it's over the top to use rsync by RA.
In addition, It may cause timed-out of monitor.

I recommend using restart_on_promote parameter too.
because timeline-ID is incremented when promote is called.

If you use restart_on_promote="true",  Saves may be able to connect
new Master without rsync.
