      id INT UNIQUE,
      name TEXT,
      PRIMARY KEY(id)
    );

    CREATE TABLE line_stops_sequence(
      id SERIAL PRIMARY KEY,
      line INT,
      stop INT,
      CONSTRAINT fk_line FOREIGN KEY(line) REFERENCES line(id),
      CONSTRAINT fk_stop FOREIGN KEY(stop) REFERENCES stop(id)
    );

当我启动下面这句话时

INSERT INTO line(id, name) VALUES (1, 'Line 1');
INSERT INTO stop(id, name) VALUES (2, 'Stop 2');
INSERT INTO line_stops_sequence(line, stop) VALUES (1,1), (1,2) ON CONFLICT ON CONSTRAINT …
