surprisingly easy. 1. if I'm calling directly, I can just use a raw sql query 2. views can be backed with a read only ecto model 3. triggers can be set to run without your ecto code even being aware of it. 4. for custom errors, you can add overides for the error handling in ecto to transform things like deadlocks to 400 errors
