我很难理解如何从我正在使用的数据库中正确转置此表。该表是由几年前设计数据库的人创建的，但我设法使用 检索该表的创建语句pg_dump。

下面是带有示例条目的表：

CREATE TABLE response (
    session_id integer NOT NULL,
    seconds integer NOT NULL,
    question_id integer NOT NULL,
    response character varying(500),
    file bytea
);

INSERT INTO response(session_id, seconds, question_id, response, file)
VALUES (758,1459505869,31,'0',''),  (758,1459505869,32,'0',''), 
(758,1459505869,33,'0',''), (758,1459505869,34,'0',''), 
(758,1459505869,35,'1',''), (758,1459505869,36,'0',''), 
(758,1459505869,37,'0',''), (758,1459505869,38,'0',''), 
(758,1459506973,38,'0',''), (758,1459506973,37,'0',''), 
(758,1459506973,36,'0',''),(758,1459506973,35,'1',''),  
(758,1459506973,34,'0',''),(758,1459506973,33,'0',''),  
(758,1459506973,32,'0',''),(758,1459506973,31,'0',''),
(758,1459508676,31,'0',''),(758,1459508676,32,'0',''),  
(758,1459508676,33,'0',''),(758,1459508676,34,'0',''),  
(758,1459508676,35,'1',''),(758,1459508676,36,'0',''),  
(758,1459508676,37,'0', ''),    (758,1459508676,38,'0', '');
