The TypedDict for this only has the fields for dj-database-url, not the rest of them. Even with the total=False setting, I still get error: Extra key "TEST" for TypedDict "_DBConfig" out of mypy when trying to set the TEST setting later on.

Thanks! Feel free to submit a PR improving the situation :)

Yeah, I had mentioned it here: #7979 (comment)

Like Alex mentioned, feel free to do a PR, otherwise, I'll take care of it, sometime next week.
