Comment (by Nick Stefan):
postgresql and mysql are fine. However, for SQLite to use ON DELETE, we
would need a new OPTIONS flag. Something like:
{{{
settings.DATABASES.["default"]["OPTIONS"]["PRAGMA_foreign_keys"] = True
}}}
(which would then lead to the database wrapper running the correct SQL:
https://sqlite.org/foreignkeys.html#fk_enable)
If I add the pragma flag, the test suite fails quite a few tests (50+).
Therefore, SQLite PRAGMA foreign keys, seems to be a bigger and separate
scope. It does have its own ticket here
https://code.djangoproject.com/ticket/14204. So postgresql and mysql are
it, for now.
