重启后再次修改测点的tag发现没法按照tag做查询了

[juice411]

1.老版本是11.3，加了测点
2.后面升级到11.5后，在次修改测点（sql=ALTER timeseries {} UPSERT ALIAS={} TAGS(name='{}',dir='{}',exName='{}',description='{}',unit='{}') ATTRIBUTES(minValue={},maxValue={})），sessionPool.executeNonQueryStatement(sql)修改是正常提交了，但完成后根据tag查不到数据
3.实在没有办法就删除了测点 delete timeseries,重新添加测点
4.再次查询，发现可以正常了

复现过程：

1. bm在release 0.11.3上生成数据
   bm配置文件：
   INSERT_MODE=session
   IS_CLIENT_BIND=true
   CLIENT_NUMBER=10
   GROUP_NUMBER=1
   DEVICE_NUMBER=1
   SENSOR_NUMBER=6
   BATCH_SIZE=1000
   LOOP=10000
   IS_OVERFLOW=false
   OPERATION_PROPORTION=1:0:0:0:0:0:0:0:0:0:0

2. Rel 0.11.3 cli 修改序列增加tags信息
   show timeseries;
   flush
   alter timeseries root.group_0.d_0.s_2 UPSERT ALIAS=alias_s2 TAGS(tag='hi',tag2='hello') ATTRIBUTES(attr1='red',attr2='blue')
   // 根据tag信息查询时间序列 结果正确 不报错
   show timeseries root.group_0.d_0 where tag2='hello';
   show timeseries root.group_0.d_0 where tag='hi';
   

3. 重启0.11.3 或 copy 0.11.3的data到rel 0.11.4/0.11.4 cli根据tag查询序列报错
   show timeseries root.group_0.d_0 where tag2='hello';
   Msg: 500: The key tag2 is not a tag.
   
   show timeseries可以看到tags信息

复现过程2：

1. bm在release 0.11.3上生成数据
   同上
2. 0.11.3 cli修改时间序列，增加tag信息
   alter timeseries root.group_0.d_0.s_2 UPSERT ALIAS=alias_s2 TAGS(tag='hi') ATTRIBUTES(attr1='money')
   flush
   3.copy 0.11.3的data到rel 0.11.4
