Re: [PATCH] pgbench --throttle (submission 7 - with lag measurement)

Hello Greg,

Thanks for the improvement!

I have a small reservation about "finish/end time schedule" in the second
paragraph, or maybe there is something that I do not understand. There is
no schedule for finishing anything, only start times are scheduled, so I
wish the text could avoid suggesting that finish time are scheduled.

-> That approach means that long transactions can result in later
transactions to be late with respect to the schedule, while short
transactions makes it possible for late ones to catch up again.

Would you be ok with that?
