I don't think the PostgreSQL project should wait any longer on this. If
it does we risk loss of quality in final release, assuming no slippage.

>From here, I will rework my patch of 31 May to
* use arrival time on standby as base for max_standby_delay
* make delay apply to both streaming and file cases
* min_standby_grace_period - min grace on every query, default 0

Decision time, so thoughts please?
