Hi hackers,

> Thanks, done!

Dilip Kumar asked a good question in the thread about the 0001..0003
subset [1]. I would like to duplicate it here to make sure it was not
missed by mistake:

"""
Have we measured the WAL overhead because of this patch set? maybe
these particular patches will not impact but IIUC this is ground work
for making xid 64 bit. So each XLOG record size will increase at
least by 4 bytes because the XLogRecord contains the xid.
"""

Do we have an estimate on this?
