Well, true actually tells us that the attribute is null, since that's the purpose of the function: /* * slot_attisnull * Detect whether an attribute of the slot is null, without * actually fetching it. */ I think the comment is more meaningfull before the change since it tells us how nonexisting columns are interpreted.
