Hi, When reviewing some parallel apply related codes, I noticed a bug in the parallel apply worker, similar to the issue discussed in this thread.
The issue is that the logical replication parallel apply worker may erroneously advance the origin progress during an error or unsuccessful apply. This can lead to transaction loss, as these transactions will not be resent by the server. Commit 3f28b2fc addressed a similar issue in both the apply worker and table sync worker. The original fix involved registering a before_shmem_exit callback to reset the origin information, preventing the worker from advancing it during transaction abortion on shutdown. The attached patch registers the same callback for the parallel apply worker, ensuring consistent behavior across all workers. Best Regards, Hou zj
