>CREATE EVENT TRIGGER</A
>.
     In order to create an event trigger, you must first create a function with
     the special return type <TT
CLASS="LITERAL"
>event_trigger</TT
>.  This function
     need not (and may not) return a value; the return type serves merely as
     a signal that the function is to be invoked as an event trigger.

     fire in alphabetical order by trigger name.
