But please note that this patch is a bug fix to address the performance issue that is causedby having to rewrite the entire table when all-visible bit is set on the page during first vacuum. So while we maydo some more work during COPY FREEZE, we're saving a lot of page writes during next vacuum. Also, since the scan thatwe are doing in this patch is done on a page that should be in the buffer cache, we will pay a bit in terms of CPU cost,but not anything in terms of IO cost. > > Agreed.

I have removed Ibrar as a reviewer since there has been no review from them in three weeks, and too encourage others to have a look. Regards, -- -David
