afterTriggerInvokeEvents and AfterTriggerExecute have always treated it as an error if the trigger OID mentioned in a queued after-trigger event can't be found. However, that fails to account for the edge case where the trigger's been dropped in the current transaction since queueing the event. There seems no very good reason to disallow that case, so instead silently do nothing if the trigger OID can't be found. This does give up a little bit of bug-detection ability, but I don't recall that these error messages have ever actually revealed a bug, so it seems mostly theoretical. Alternatives such as marking pending events DONE at the time of dropping a trigger would be complicated and perhaps introduce bugs of their own. Per bug #18517 from Alexander Lakhin. Back-patch to all supported branches. Discussion: https://postgr.es/m/18517-af2d19882240902c@postgresql.org |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. 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. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
