Hello
+ /* Only verify tuples pointing to visible heap rows */
+ if (!heap_entry_is_visible(state, tid))
+ return;
...
+ slot = table_slot_create(state->heaprel, NULL);
+ found = table_tuple_fetch_row_version(state->heaprel, tid,
+ state->snapshot, slot);
+ if (!found)
+ {
This seems like a duplication, heap_entry_is_visible does the same
thing and returns found.
This also means that the if (!found) block should be unreachable?
Wouldn't it be simpler to remove the is_visible check completely and
use an if(found) later?
+ indexinfo = state->indexinfo;
+ estate = CreateExecutorState();
+ GetPerTupleExprContext(estate)->ecxt_scantuple = slot;
+ FormIndexDatum(indexinfo, slot, estate, values, isnull);
+ FreeExecutorState(estate);
This doesn't need the same cleanup code as heapam.c:1754 and :1997?
Seems like state remains, so we have dangling pointers there and could
crash later.
/* These may have been pointing to the now-gone estate */
indexInfo->ii_ExpressionsState = NIL;
indexInfo->ii_PredicateState = NULL;
