Description
The return bool(cursor.rowcount) is outside of the with block, so the cursor will have been closed at that point.
From the DB API 2.0 spec: "The cursor will be unusable from this point forward" https://www.python.org/dev/peps/pep-0249/#Cursor.close
As the main backend drivers don't mind it I suppose that is is open to interpretation.
Here is a basic PR https://github.com/django/django/compare/main...ecogels:fix-dbcache-delete-1
