URL: https://github.com/apache/shardingsphere/issues/22576
### Which version of ShardingSphere did you use?
we find java version: java8, full_version=1.8.0_342, full_path=/home/peilq_sharding/bisheng-jdk1.8.0_342//bin/java
ShardingSphere-5.2.2-SNAPSHOT
Commit ID: dirty-753c0cee8ee6fd3db00536da55b64bc5198a3758
Commit Message: Optimize sqlFederationExecutor init logic when sqlFederationType modify dynamically (https://github.com/apache/shardingsphere/pull/22209)
Branch: https://github.com/apache/shardingsphere/commit/753c0cee8ee6fd3db00536da55b64bc5198a3758
Build time: 2022-11-19T10:18:41+0800
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
In the federation scenario，the priority of ‘UNION/EXCEPT/INTERSECT ’ is correct.
### Actual behavior
In the federation scenario，the priority of ‘UNION/EXCEPT/INTERSECT ’ is incorrect.
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
```
(select * from t_order where order_id = 1500 union select * from t_order where order_id = 1800 )INTERSECT select * from t_order where status ='finish' order by order_id;
select * from t_order where order_id = 1500 union (select * from t_order where order_id = 1800 INTERSECT select * from t_order where status ='finish' order by order_id); --incorrect

According to PostgreSQL document - https://www.postgresql.org/docs/current/queries-union.html, if we add order by segment in top level of sql, the results of set operations are not guaranteed to be ordered.
> UNION effectively appends the result of query2 to the result of query1 (although there is no guarantee that this is the order in which the rows are actually returned). Furthermore, it eliminates duplicate rows from its result, in the same way as DISTINCT, unless UNION ALL is used.
