    Yes, because I changed the query. The original query performs the self-join 
on ```nation```, which makes the query plan non-deterministic. So, I changed it 
to the join of ```nation``` and ```small_nation``` which is derived from the 
```nation``` table.

> Many unit tests include master plan verification. However, sometimes, the 
> order or enforcers of the master plan is changed, which in turn causes the 
> test failure.
