Interesting. I don't think this was ever mentioned as a possible use case for BEFORE triggers on partitioned tables, during the pg11 development. Basically we forbade BEFORE triggers on partitioned tables. (You can find the reasons for that in the thread that discussed row trigger development). > Other than creating a bunch of partitions in advance, what are my options? Create *one* partition in advance? Another option would be to contribute the feature of automatically creating the partitions for Postgres 12 :-) -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
