The logical replication parallel apply worker could incorrectly advance the origin progress during an error or failed apply. This behavior risks transaction loss because such transactions will not be resent by the server. Commit3f28b2fcacaddressed a similar issue for both the apply worker and the table sync worker by registering a before_shmem_exit callback to reset origin information. This prevents the worker from advancing the origin during transaction abortion on shutdown. This patch applies the same fix to the parallel apply worker, ensuring consistent behavior across all worker types. As with3f28b2fcac, we are backpatching through version 16, since parallel apply mode was introduced there and the issue only occurs when changes are applied before the transaction end record (COMMIT or ABORT) is received.
