Don't try to be smart with the sizes, just use 16 bytes for both and in the snprintf use 16 also, then everything will work fine. > HeapTuple data; > Datum finalResult; > data = BuildTupleFromCStrings(attinmeta, output); Although I think you're going the long way round, you can build a tuple from the integer wtihout making a string first...
