IP of the entity that does auth, IP of entity that submits request

Hi there. When provisioning a database, could you please inject a function like auth.ip() (beside auth.uid, auth.role, auth.email) into the auth schema to achieve this: ip of the entity that does auth, ip of entity that submits request

Something along the following lines?

current_setting('request.headers', true)::json->>'x-forwarded-for'

This function could then be used when defining RLS policies

Thanks
