Love the simplicity of this project in use, but I've come across an issue - how to avoid inserting duplicates?
It appears I would need to bypass the client and check each entry with the underlying connection before db.add. This just feels out of place with the simplicity of the rest of the interface, particularly as it would then need knowledge of the underlying schema and be brittle to future changes.
My particular usecase utilises text to store long hashes, so it would be ideal to treat them as unique - and I assume the same would be true for the plain text uses in the examples too.
