Prevent recursive trigger in PostgreSQL

Question

How to prevent recursive execution of trigger? Let\'s say I want to construct a \"tree-able\" description on chart of account. So what I do is when a new record is inserted

Answer 1

At the beggining of the definition of the trigger you can disable triggers on that particular table, and reenable them at the end (and make sure an exception doesn't terminate the execution before expected!). This has many deep holes, but may work for some light implementations. Notice that for this implementation, you will also need priviliges to disable triggers.
