Just to avoid any confusion with the patch I sent out this week, we are setting HEAP_UPDATE_ROOT on all tuples which are HOT-updated. We set HEAP_ONLY_TUPLE for all tuples which does not have index reference. So may be combination of (HEAP_UPDATE_ROOT & ~HEAP_ONLY_TUPLE) can be used to identify index referred tuple in a HOT-update chain. Thanks, Pavan -- EnterpriseDB http://www.enterprisedb.com
