From PostgresSQL:
```
If the array expression yields a null array, the result of ANY will be
null. If the left-hand expression yields null, the result of ANY is ordinarily
null (though a non-strict comparison operator could possibly yield a different
result). Also, if the right-hand array contains any null elements and no true
comparison result is obtained, the result of ANY will be null, not false
(again, assuming a strict comparison operator). This is in accordance with
SQL's normal rules for Boolean combinations of null values.
```
It's more consistent in PostgresSQL, I'd like to follow it.
