## Bug Report
### Which version of ShardingSphere did you use?
5.1.2
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
Execute select statement and return query result successfully when I query
the sharding tables.
### Actual behavior
The ShardingSphere-JDBC return an error:
org.mybatis.spring.MyBatisSystemException: nested exception is

### Reason analyze (If you can)
The ShardingSphere-JDBC can not get shard table's meta information for aws
aurora postgresql 14.11 version when the db user is not same with the table
owner.Since everything works well with postgresql 12.8 before I upgrade the db
to postgresql 14.11 version.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
1.Create one aws aurora postgresql cluster which engine version is 14.11,and
create two database db1 and db2;
2.Create a table both in db1 and db2, change the table owner to user2;
alter table owner to user2;
3.Set ShardingSphere-JDBC db user as user1
```yaml
dataSources:
ds_0:
url:
jdbc:postgresql://xxx.cluster-ckcvjkzxh8bd.ap-northeast-1.rds.amazonaws.com:5432/db1?prepareThreshold=0
username: user1
password: user1password
connectionTimeoutMilliseconds: 30000
idleTimeoutMilliseconds: 60000
maxLifetimeMilliseconds: 1800000
maxPoolSize: 50
minPoolSize: 1
ds_1:
url:
jdbc:postgresql://xxx.cluster-ckcvjkzxh8bd.ap-northeast-1.rds.amazonaws.com:5432/db2?prepareThreshold=0
username: user1
password: user1password
connectionTimeoutMilliseconds: 30000
idleTimeoutMilliseconds: 60000
maxLifetimeMilliseconds: 1800000
maxPoolSize: 50
minPoolSize: 1
```
4.Config table shard rule the same as offcial example and start the
application and execute the query.
