As an effort to move on with bug items in the commit fest, attached are
two patches with a proposed commit message as well as polished comments
Those are proposed for a back-patched. The 2PC issue is particularly
bad in my opinion because having any 2PC file on-disk and corrupted
means that a transaction is lost. I have been playing a bit with
hexedit and changed a couple of bytes in one of them... If trying to
use a base backup which includes one, then the standby reading it would
be similarly confused.
