Postgres does.
I'm not really in a great hurry to implement anything like this. Django supplies a reasonable layer over SQL, but doesn't intend to cover every single case and this is on the edge. One could also argue that if you're routinely sorting by columns that contain NULLs and you rely on the NULLs being first or last, you're probably not following "best practices" at some level (and, yes, I fully realise there are counter-arguments as well). But I think we can manage to go on living without this type of option. By design, QuerySets and Query are subclassable. If you really need this support, add an extra call to your QuerySet subclass that incorporates that into the extension of Query.as_sql() and use that QuerySet subclass as the one returned by your custom manager.
