       will use this mode to insert each row's index entry.  The access
       method must allow duplicate entries into the index, and report any
       potential duplicates by returning FALSE from <CODE

>aminsert</CODE
>.
       For each row for which FALSE is returned, a deferred recheck will
       be scheduled.
