Review Comment:
the method getSchema() is overrided in Class OpenGaussDatabaseMetaData,
which will set defaultSchema first.
the code like this:
```
@Override
public String getSchema(final Connection connection) {
this.defaultSchema =
DialectDatabaseMetaData.super.getSchema(connection);
return this.defaultSchema;
}
```
