<br />ISTM that the PD_ALL_VISIBLE flag and the visibility map bit can be set at the end of pruning operation if we
knowthat there are only tuples visible to all transactions left in the page. The way pruning is done, I think it would
bestraight forward to get this information.<br /><br />Thanks,<br />Pavan<br clear="all" /><br />-- <br />Pavan
