let's *try* to start bulk inserts. It won't necessary
start them as values_list.elements should be greater than
some - handler dependent - threshold.
So we call start_bulk_insert to perform nesessary checks on
values_list.elements, and - if nothing else - to initialize
the code to make the call of end_bulk_insert() below safe.
