Dear Hackers,
This is a fork from [1].
While constructing a conflict message, CT_UPDATE_ORIGIN_DIFFERS and
CT_DELETE_ORIGIN_DIFFERS assumes that timestamp for the local commit is always
available. Actually, it's valid because they can be detected only with
track_commit_timestamp, but source code does not describe anything for it.
PSA the patch to add Assert() or it.
