Обсуждение: Transaction Triggers!
Does Postgres triggers have an "after commit" clause or plans to do so (in what release)? If NOT, then is there any way for developer's to have an "after-commit-do" mechanism?

What happens if you get an error in the "after commit" operation? You can't roll back the transaction, it's already committed. Also, my understanding of "transaction commit" is that it means all the actions of the transaction are done and guaranteed not to be lost; which is hardly possible to guarantee if some are not done yet. > If NOT, then is there any way for developer's to have > an "after-commit-do" mechanism? Your application can do whatever it likes ... recognizing that it has no guarantees about completion. regards, tom lane
