ERROR: column "task_status" is of type task_status but expression is of type character varying

org.postgresql.util.PSQLException: ERROR: column "task_status" is of type task_status but expression is of type character varying
我在数据库都能行，结果这就不行了

is of type character varying
这个错误提示是说明你操作的类型不一致导致的。
例如你task_status是字符串类型，将整型赋值给这个字段时就会报错。你需要做类型转换才行。
