Hi,while learning about format of the transaction log produced by pgbench, I've noticed this sentence in the section describing format of the per-transaction log:
The last field skipped_transactions reports the number of transactions skipped because they were too far behind schedule. It is only present when both options --rate and --latency-limit are used.Which is wrong, because this field is only added in the aggregated log, not in the per-transaction one. So we should delete this.
It also does not explicitly explain that with --latency-limit the latency column will contain "skipped" for transactions exceeding the limit latency (it's only mentioned in the example output).
So I think we should apply the attached patch (and also backpatch it to 9.5, where the --latency-limit got introduced).
