Won't take so long ;-)
I would like to stop the regression on pgbench firstly, as PeterZ
mentioned, if someone reported other regressions, we will know what is
missing, if fix is possible, we fix it, if cost is too high, then I say
we ignore the illegal income, after all, we could not benefit one in the
cost of sacrifice others...
I'd like to fix the problem ASAP, it's really a big, urgent problem on
my point of view, but doesn't win enough attentions as I thought it will...
The regression has been buried too long and hidden, if we miss the
chance to correct the issue this time, it will no doubt been buried again...
