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. Commit 3f28b2fcac addressed 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 with 3f28b2fcac, 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.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system.
