### Describe the bug When using `array_agg` (or `ARRAY_AGG`) with both `DISTINCT` and `IGNORE NULLS` clauses, the `IGNORE NULLS` clause is not being respected. NULL values are included in the result even when they should be filtered out. ### To Reproduce ```sql SELECT ARRAY_AGG(DISTINCT x IGNORE NULLS) as result FROM (VALUES (1), (2), (NULL), (2), (NULL), (1)) AS t(x); ``` ### Expected behavior ```` > SELECT ARRAY_AGG(DISTINCT x IGNORE NULLS) as result FROM (VALUES (1), (2), (NULL), (2), (NULL), (1)) AS t(x); +--------+ | result | +--------+ | [2, 1] | +--------+ ``` ### Additional context DISTINCT and IGNORE NULLS <img width="458" height="288" alt="Image" src="https://github.com/user-attachments/assets/1db0f6cd-a874-4e72-a6f5-2283851576be"; /> IGNORE NULLS <img width="438" height="140" alt="Image" src="https://github.com/user-attachments/assets/66ad6192-1a25-4a51-9f07-83adfa598f28"; /> Testing ibis from Sail https://github.com/lakehq/sail/pull/1187 -- This is an automated message from the Apache Git Service.
