[Suggestion] Validation error messages

[romanoff]

My understanding is that at the moment this extension allows you to get answer if validation failed or succeeded. But would be great if you could also error messages. Possible format:

{"name": ["is required"]}

Not sure about exact format, but that would definitely be useful in some cases (my use-case is trying to process http request in postgres function. And this would provide validation messages )

I agree, it would be nice to have this. My application doesn't need it because I validate in the application as well, and the check constraint is just for integrity.

It seems pretty hard to implement so I didn't do it, but I would accept a patch that did.
