Thank you for pointing. In future I'll maintain patches with their
description.
BTW, during FOSDEM developer meeting we decided that I should extract
64-bit in-memory representation of xids and resubmit it, while 64-bit
on-disk reprensentation should become a pluggable table access method.
I didn't manage to do this before current commitfest. Also, the last
commitfest
is already too late for such big changes. So, I'm marking this RWF.
