The problem is this: - we need to find the TupleDesc of the function's expected return type for tuple-returning functions - we can't use estate->rsi for the RETURN case, at least as presently implemented, because that is not always filled-out -- the example I gave before shows how because we don't check for a compatible TupleDesc when estate->rsi is NULL, we end up returning a value that is incompatible with the function's declared return type - therefore, we need to use some other way to get the TupleDesc of the function's declared return type. Offhand I think we can use estate->fn_rettype (plus the funcapi stuff for handling RECORDOID), but I haven't had a chance to try it yet. -Neil
