Is there a way to generate the OpenAPI/Swagger definition from Postgres with object references?

I have a rest api using supabase/postgres(t) which generates it's own OpenAPI/Swagger definition. The problem is that this only contains the id fields but not actual references to the other tables.

When generating a client with openapi-generater, the classes therefore only contain the foreign keys but not actual object references.

Is there a way to generate the openapi definition with references so I can generate my classes with references?
