Odd - at least with an earlier patch I saw optimized pgbench initialization go down by ~25%. > I went ahead and pushed it with a rewritten comment. Imo the code now is a bit odd, because we first switch (type) setting base, and then separately have branches for the different bases. Greetings, Andres Freund
