19507	django.db doesn't wrap / replace psycopg2.InterfaceError	Antoine Pitrou	nobody	"django.db currently only wraps the backend's `DatabaseError` and `IntegrityError`. However, psycopg2 can raise a ""psycopg2.InterfaceError: connection already closed"" when trying to run a query more than once against an unavailable (e.g. stopped) database. This means catching `django.db.DatabaseError` isn't enough to catch all possible runtime errors (other than programming errors).

It would be nice if Django also replaced psycopg2's `InterfaceError` with a generic Django exception.
