note that this doesn't use database-level restrictions, this behaviour
is emulated at the ORM level. IOW: any deletion done via the ORM will
respect the on_delete option, but anything done with direct SQL won't.

you can (maybe should) add a 'initial sql' [1] parameter to set any
DB-level restriction like this.
