> Yea I think this is common sense. Do other systems have `array_contains` function and how do they handle null? Current behavior seems to match how we handle IN lists (and those are in the SQL standard): select null in (1, 2, null); -- returns NULL, not true. Fundamentally, if array_contains() uses equality to establish whether an element belongs to an array, then NULL = NULL returns NULL, not true. -- This is an automated message from the Apache Git Service.
