Database constraints are extremely valuable - it's the only way to guarantee certain conditions (especially uniqueness).
Have you tried increasing logging level, and checking logs for what queries are actually performed? You can also run `rake db:schema:dump` (or even db:structure:dump) on the production to get production database schema and verify it. Maybe loading dump of the production database locally (if that's possible for you - privacy, etc.) can help you debug those issues.
