Thanks. Regarding: <!-- Author: Alvaro Herrera <alvhe...@alvh.no-ip.org> 2022-03-20 [ba9a7e392] Enforce foreign key correctly during cross-partition upd --> <listitem> <para> Improve the trigger behavior of updates on partitioned tables that move rows between partitions (Amit Langote) </para> <para> Previously, such updates fired delete triggers on the source partition and fired insert triggers on the target partition. PostgreSQL will now fire an update trigger on the partition root. This makes foreign key behavior more consistent. ALL TRIGGERS? </para> </listitem> The commit is intended to only change the behavior of RI triggers, while leaving user-defined triggers firing as before. I think it might be a good idea to be specific by wording this, maybe as follows? Improve the firing of foreign key triggers during cross-partition updates of partitioned tables (Amit Langote) Previously, such updates fired delete triggers on the source partition and insert triggers on the target partition, whereas PostgreSQL will now fire update triggers on the partitioned table mentioned in the query, which makes the behavior of foreign keys pointing into that table more consistent. Note that other user-defined triggers are fired as they were before. -- Thanks, Amit Langote EDB: http://www.enterprisedb.com
