Your trigger is wrong. You try to insert the same row twice.
I assume you didn't try it. If active_at field is null then the trigger
does another insert instead of the original one. This avoids looping or
inserting twice.
The only mistake is that I tought the insert with select will be atomic
and I was wrong. So the trigger has concurrency problem in
multi-threaded environment. It runs flawlessly in single thread and it
does only a single insert.
