Here is a review.
Patch applied, compiled and run. Note that it needs a rebase after pgbench
move to src/bin.
Overall comments:
This feature is a good think, i.e. it removes a current limitation which
is not really logical.
I think that the user interface must be improved. I would suggest that
option "-a/--aggregate-log" should trigger the aggregate log with a
default aggregate interval of for instance 1 or 10 second(s), and
"--aggregate-interval" would change the default interval.
Probably this patch could wait for the resolution of the pgbench merged
log patch submitted in parallel as it seems to me that it interferes
significantly with it.
Detailed comments:
In doLog, the sample rate test should be mixed in the tlogfile condition
so as to avoid calling rand if there is no logging anyway.
if (tlogfile && sample_rate != 0 && ...)
The aggregate log file opening error refers to the "transaction" log file.
The documentation update is missing.
