Also: as long as we are building a custom-hacked executable to probe
into this, let's hack it to not remove the 2PC state file, so we can
double check what's really in there. I believe what you'd need to
remove is the RemoveTwoPhaseFile calls at twophase.c line 1583 (where
it thinks it's "stale") and xact.c line 4223 (where it's replaying a
XLOG_XACT_COMMIT_PREPARED WAL record).
