Re: [PATCH] pgbench --throttle (submission 4) Michael Paquier <michael.paquier@gmail.com>

New submission for the next commit fest.

This new version also reports the average lag time, i.e. the delay between 
scheduled and actual transaction start times. This may help detect whether 
things went smothly, or if at some time some delay was introduced because 
of the load and some catchup was done afterwards.

Question 1: should it report the maximum lang encountered?

Question 2: the next step would be to have the current lag shown under 
option --progress, but that would mean having a combined --throttle 
--progress patch submission, or maybe dependencies between patches.
