I generally agree that, in most cases, you want the NULLS DISTINCT behavior. But thank you for providing such a developer-friendly feature that allows flexibility here! NULL in SQL is not terribly consistent overall. Sometimes NULL is treated like "unknown" and sometimes more like "n/a". And the interaction with non-scalar types (like records) is pretty strange. Also, it's common for ORMs to map the app language's NULL (or None/Nil/whatever) to SQL NULL, which adds its own nuance. So I can see this being a useful feature. |
