Even subscribing to this view point, there is sure to be a significant wiggle
room in what people find to be "sufficient monitoring". If I had to score the
monitoring facilities we have for PITR standby, I'd give it about a crap out
of 5, and yet somehow we seem to manage it.

I'm certainly interested in specifics of what you think need to be exposed for
monitoring, and I'd be interested in whether those things can be exposed as
either trace points or possibly as C functions. My guess is that we won't get
them into core for 8.5, but that we might be able to provide some additional
facilities after the fact as we get more of these systems deployed.
