I rebased the patch set on the master (7e5e1bba03), and the regression
test is good. Therefore, I changed the status of the patch: "needs review".
I know that you proposed the new extended statistics[1], and it probably
conflicts with the patch. I hope my patch will get commit before your
patch committed to avoid the time of recreating. :-)
