大家可以看到，这跟普通的data block的dump内容是有所差别的，因为这里涉及到cluster table。

下面来模拟下手工提交cluster table的事务。

这里我们可以看到对于这个未提交的事务XID为：3.17.1212  前面我们已经知道
测试表中的数据分布在3个block中，这里我模拟的情况是删除第3条数据，且不提交，通过bbed来实现手工
提交这个未提交事务，注意：第3条数据是在第3个block中，即174 block。

+++++首先修改表的itl等信息

我们可以看到，无论怎么修改，这个block通过bbed进行检测都报错，这里不是因为修改的不对,而是因为
还需要修改cluster 上的Index信息。通过treedump 我们可以确认index block为file 6 block 187.

可以看到，该index block中还存在3个index entry信息，我们需要将第3条信息给删掉，首先计算一下offset：
