The attached adds two new command line switches to pgbench:

From your patch I see that it augments the -l flag. IMHO it does not make
sense to add another flag. We can save the "if" check and log the extended
contents as part of -l itself.
-X: Do extra cleanup after the run (vacuum on all tables, checkpoint)
before stopping the clock. This gives substantially more consistancy in
results between runs.
I am sorry, but I do not understand the above. If I read it correctly, are
you suggesting that the same database with a prior pgbench run be used for
further pgbench runs? How is it useful? How can one guarantee consistency of
observed tps values with this in place?
