+1 for that. We should associate before row triggers with the partitioned table and not with the partitions. Those should be executed before tuple routing (for that partition level) kicks in. But then that would be asymetric with AFTER row trigger behaviour. From this POV, pushing AFTER row triggers to the individual partitions doesn't look good. Other question that comes to my mind is what happens when rows are inserted into a partition directly. Do we execute BEFORE trigger on the partitioned table? -- Best Wishes, Ashutosh Bapat EnterpriseDB Corporation The Postgres Database Company
