I've pushed the SyncPostCheckpoint change, and I think I'm going
to stop here. It's not clear that the remaining list_delete_first
callers have any real problem; and changing them would be complex.
We can revisit the question if we find out there is an issue.
Or, if somebody else wants to pursue the issue, feel free.
regards, tom lane
