Thank you for reviewing this patch, and sorry for my late reply.

I've measured the performance improvement of this patch, but I got the
result showing that it can improve vacuum freeze performance 30 sec
with 32TB table. I don't think that this patch is worth to pursue any
further, so I'd like to withdraw this.
