Previously, FOR EACH ROW triggers were not allowed in partitioned tables. Now we allow AFTER triggers on them, and on trigger creation we cascade to create an identical trigger in each partition. We also clone the triggers to each partition that is created or attached later. This means that deferred unique keys are allowed on partitioned tables, too.
