I'm not entirely sure if this is even supposed to work. Certainly prior
to the transmission to the client the tuple will be converted to text,
so you'll have to parse the result. The question for me is why are you
returning heaptuples and not just a resultset which you can access via
the normal functions.

There are no client side functions to deal with heaptuples.

Have a nice day,
