So sorry for the confusion, you are right that these are 2 quite unrelated problems.
I misunderstood the 'stop the worker' here.


+                /* Immediately stop the worker. */
+                logicalrep_worker_stop_at_commit(subid, relid); /* prevent re-launching */
+                logicalrep_worker_stop(subid, relid); /* stop immediately */

Do you think we can add some comments to describe what type "worker" is stop here ? (sync worker here) 
And should we add some more comments to talk about the reason of " Immediately stop " here ? it may looks easier to
understand.
