         Used when the underlying database is configured to use the Heap
         access method. This method returns the number of pages in a region.
         This value may be set using the
         <a class="xref" href="dbset_heap_regionsize.html" title="Db::set_heap_regionsize()">Db::set_heap_regionsize()</a>
         method.

                failure, and returns 0 on success.
