You're right. Sorry. I shouldn't post when I'm tired. This is listed as a limitation in Alembic, from memory.

Edit: I looked[0]. While it is a SQLite limitation, Alembic does seem to have a way to work around it.

I was asking, not correcting you!

Django ORM also uses the same copy and move method but it warns you against doing it on production databases: "same copy and move method but it warns you against doing it on production databases".

That makes me reluctant to use SQLite for a use case it is otherwise well suited to: multi-tenant applications.

Alembic does not have such dire warnings, but still looks problematic with regard to constraints?
