These barely work. Even their example shows it generating `type : string[]` but `weaknesses : Weakness[]`. You would need to start from a schema definition (JSON Schema, SQL CREATE TABLE, etc.) to make the result any good.
For one of my projects I check in the generated types and replace 'unknown' (from jsonb) with the specific object manually. That way the concept of any or unknown gets pushed mostly out of the codebase (for simple crud. When joining we use normal SQL queries with some helper tools that verify the fields we are picking exist). Hopefully will manage to figure out how to do with with postgres comments at somepoint.
