What could happen is that the standby could slowly lag behind master. We

I agree that the statistical information about replication activity is

I don't think anybody can deploy this feature without at least some very
basic monitoring here. I like the basic proposal you made back in

have to get from ps right now:

That's basic, but enough that people could get by for a V1.
