大家有没有遇到 postgresql 数据库 ORM查询报异常，但是用sqlcallback 却成功的问题？
List infos = dao.query(Comminfo.class, Cnd.where("bcdtype", "=", 0), dao.createPager(1, 50));
该查询会报异常

Exception in thread "main" org.nutz.dao.DaoException: !Nutz SQL Error: 'SELECT * FROM COMMINFO  WHERE BCDTYPE=? LIMIT 50 OFFSET 0 
    | 1 |
    |---|
    | 0 |
  For example:> "SELECT * FROM COMMINFO  WHERE BCDTYPE=0 LIMIT 50 OFFSET 0 "'
PreparedStatement: 
'SELECT * FROM COMMINFO  WHERE BCDTYPE=? LIMIT 50 OFFSET 0 '
CaseMessage=错误: 操作符不存在: integer = character varying
  建议：没有匹配指定名称和参数类型的操作符. 您也许需要增加明确的类型转换.

但是SqlCallback 模式却不会，两者生成的sql应该都是一样的

String sql = "SELECT * FROM COMMINFO  WHERE bcdtype=@bcd LIMIT 50 OFFSET 1";
            Sql  sqls = Sqls.create(sql);
            sqls.params().set("bcd", 0);
            sqls.setCallback(new SqlCallback() {
                @Override
                public Object invoke(Connection conn, ResultSet rs, Sql sql) throws SQLException {
                    int cmmid = 0; 
                    while (rs.next()) {                        
                        cmmid  = rs.getInt("commid");
                        System.out.println(cmmid);
                    }
                    return cmmid;
                }
            });
            
            dao.execute(sqls);
            

这个是数据库的问题，还是 Nutz 的ORM问题？
