This avoids calling cursor_to_dict and then immediately unpacking the values in the dict for other users. By not creating the intermediate dictionary we can avoid allocating the dictionary and strings for the keys, which should generally be more performant. Additionally this improves type hints by avoid Dict[str, Any] dictionaries coming out of the database layer.
