21146	DatabaseCache doesn't work if database backend returns datetime values as strings	Michael Manfre	nobody	DatabaseCache intentionally uses cursors and converts all datetimes to naive values. This is a problem for database backends that return datetimes from the database as strings that must be converted to a datetime before being used. All reads of the '''expires''' column should be passed through {{{DatabaseOperations.convert_values}}}, and {{{timezone.make_naive}}} to maintain the current naive-only datetimes behavior.
