The whole point of schemas is data validation, and the hard part of "iterating quickly" is migrating data in a way you ensure it remains valid. Neither of these requirements are tied to relational databases. At most, breaking a schema ensures you cannot proceed with broken data without undergoing a migration, or completely wiping your database. But you are already doing that, aren't you?
