A different and more important issue (IMO) is that the xlog record
header currently only supports 32-bit xids -- long-running
transactions can reasonably see a xid4 wraparound in their lifetime.
You're completely right. This is a first of making xid's 64-bit proposed [1] i.e, making SLRU 64-bit [2]
