In response to Jignesh Shah :
> Thanks Kretschmer. Could you tell me what "return new" meant for?
A trigger function must return either NULL or a record/row value having
exactly the structure of the table the trigger was fired for. Okay, in
this case, you can also return NULL. NEW means the new record, but you
need it only for row level triggers afaik.
