After reading the source code for nodeHash.c and tuplesort.c, I decided to
create new struct containing MinimumTuple and few members.
I am still wondering in one thing:
typedef struct HashJoinTupleData
{
struct HashJoinTupleData *next;/* link to next tuple in same
bucket */
uint32
I see. Thanks for the advice. I would research on how to use tuplestore
object.

Until you next call that same plan node.

I see.
Hmm how if an upper level node needs to store (for future use) the
TupleTableSlot* returned by lower level node, e.g. I create a specialized
Sort Node which needs to read all tuples from lower level nodes. In this
case, would it be necessary and sufficient to make a copy the TupleTableSlot

Hello,
As per title, what is the lifetime of the virtual tuple TupleTableSlot*
returned by ExecProcNode?
Any help would be appreciated.
