typedef bool (*aminsert_function) (Relation indexRelation,
  Datum *values,
  bool *isnull,
  ItemPointer heap_tid,
  Relation heapRelation,
  IndexUniqueCheck checkUnique,
  bool indexUnchanged,
  struct IndexInfo *indexInfo);

Why is there a heap_tid, We haven’t inserted the value, so where does it from ?
