28974	Model.refresh_from_db() should pass the refreshed instance as a database hint	Simon Charette	nobody	"While reviewing the patch for #28918 and reflecting about #28939 I noticed that the `refresh_from_db()` method [https://github.com/django/django/blob/d065c92678f5d11a70b88e195c6357576eb3a2ef/django/db/models/base.py#L593 was duplicating] the work [https://github.com/django/django/blob/d065c92678f5d11a70b88e195c6357576eb3a2ef/django/db/utils.py#L261-L263 the routers do] when an `instance` hint is provided.

I figured out that we we're better of using `db_manager(using, hints={'instance': self})` in this case which would also have the benefit of passing down `instance` as an hint to possibly defined custom routers."
