Hi, I am pretty new to the Postgres code base. I would like to know the difference between HeapTupleData and TupleTableSlot structures.
Basically I am trying to understand some of the table access methods like heap_insert, heap_getnext, heap_getnextslot etc where some accepts Heaptuple as input and some accepts TupleTableSlot. Could anyone please help me to understand this? Any example would also be helpful. Best, Ajay
