        status is checked when the event occurs, not when the trigger function
        is actually executed.  One can disable or enable a single
        trigger specified by name, or all triggers on the table, or only
!       user triggers (this option excludes triggers that are used to implement
!       foreign key constraints).  Disabling or enabling constraint triggers
        requires superuser privileges; it should be done with caution since
        of course the integrity of the constraint cannot be guaranteed if the
        triggers are not executed.
