Well, you don't need it. I assume there's still a way to stop it,
though, and a failed demote will result in a stop.

So adding the master/slave functionality to the pg agent seems to make
sense still.

However, if there are fundamental conceptual problems with the m/s
implementation of our RA and the PG approach (and perhaps mysql?) we may
want to also extent the design of the m/s. Got any thoughts on that?
