It could be. Before that, my patch does not wake up hot standby
because I didn't care of minRecoveryPoint in it:-p
On the other hand, your patch fixes that point but ReadRecord
runs on the false page data. However the wrong record on the
false page can be identified as broken, It should be an
undesiable behavior.
If we want to show the final solution by ourselves, we need to
make another patch to settle them all. Let me take further
thought..
