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 September
for adding a pg_standbys_xlog_location to replace what you have to get from
ps right now:

That's basic, but enough that people could get by for a V1.
Yeah, I have no objection to add such simple capability which monitors
the lag into the first release. But I guess that, in addition to that,
Simon wanted the capability to collect the statistical information about
replication activity (e.g., a transfer time, a write time, replay time).
So I'd like to postpone it.
yeah getting that would all be nice and handy but we have to remember
that this is really our first cut at integrated replication. Being able
to monitor lag is what is needed as a minimum, more advanced stuff can
and will emerge once we get some actual feedback from the field.
