您不应该在select中指定列。尝试删除它们：

INSERT INTO Exhibits (
        "Name",
        "Start_Date",
        "End_Date",
        "Description")
SELECT
        'Modern America and the Contemporary World',
        CASE WHEN (
                SELECT COUNT(End_Date) 
                FROM exhibits 
                WHERE End_Date>CURRENT_DATE) >= 3 
             THEN (
                SELECT Min("End_Date")+5 
                FROM exhibits
                WHERE End_Date>CURRENT_DATE) 
             ELSE '2016/05/19' END,
        '2017/01/10',
        'lolololololololol'
;
