Well, the standby might be persuaded to know something about the master,
but not the other way around. The master:standby relationship is 1:Many,
and not restricted in the way things are daisy-chained. So it's more
than just a pair of servers.
All the slaves will say they are the same if you ask them, so you can't
rely on that to identify them. So you need to specify which two servers
you're interested in comparing and how to identify them externally.
