A minor correction in comment in heaptuple.c

Hi,

Should it be: "return true if attnum is out of range according to the
tupdesc" instead of "return NULL if attnum is out of range according
to the tupdesc" at src/backend/access/common/heaptuple.c: 1345

/*
 * return true if attnum is out of range according to the tupdesc
*/
if (attnum > tupleDesc->natts)
return true;

Attached patch fixes this.
