Change TupleTableSlot->tts_nvalid to type AttrNumber.
Previously it was an int / 4 bytes. The maximum number of attributesin a tuple is restricted by the maximum value Var->varattno, which isan AttrNumber/int16. Hence use the same data type forTupleTableSlot->tts_nvalid.Author: Ashutosh BapatDiscussion:https://postgr.es/m/20180220224318.gw4oe5jadhpmcdnm@alap3.anarazel.de
