Hello list,
I would like to be able to send the HeapTuple returned
by ExecFetchSlotTuple() over the network (socket) to
another postmaster process that's waiting for it. I
don't need to decode it, just send bytes.
My question, and I am not a DB expert, I just deal
with raw data. What other information do I need to
include from struct HeapTupleData in order for that
data to make sense on the other end (to rebuild a
HeapTuple from it).
I understand that:
data_address = offset(HeapTupleHeaderData,
tuple->t_data->t_hoff);
data_len = tuple->t_len - tuple->t_data->t_hoff;
tuple->t_data->t_ctid and tuple->t_data->t_natts are
needed for this. Is that it?
What do I need to watch for with TOAST'ed tuple?
I will basically create a temp struct that will hold
those necessary information and sent that struct.
Thank you,
tjjr
