It still doesn't work. btw, I am using 8rc2.
changed it to:
Datum result;
HeapTuple tupleCopy;
tupleCopy = heap_copytuple(tuple);
result = HeapTupleGetDatum(tupleCopy);
SRF_RETURN_NEXT(funcctx, result);
its probably something with the column description. the rows are
returned ok with select testgetrows();
but not with select * from testgetrows();
Regards,
tzahi.
