(on pgjdbc/src/main/java/org/postgresql/jdbc/PgArray.java)

This fails because `array` is declared as an array holding non-nullable, so the checker forbids assigning `null` there.

If you need nullable array of nullable objects, then you need to declare it as `@Nullable Object @Nullable [] array`

Here's a quick tip: https://github.com/pgjdbc/pgjdbc/blob/master/CONTRIBUTING.md#null-safety

```java
  // array and elements: non-nullable
  String[] x;

  // array: nullable, elements: non-nullable
  String @Nullable [] x;

  // array: non-nullable, elements: nullable
  @Nullable String[] x;

  // array: nullable, elements: nullable
  @Nullable String @Nullable [] x;
```
