How to verify input data?

Django has a form that can verify the data sent by the user on the server side. How does supabase do it?

Postgres has a check option for columns. You can use simple or complex checks including regex.

Postgres check constraints fail fast, but one usually wants validation to return a full list of errors to the user. This is suboptimal.
