I thought I was missing something. Third option. As example:

https://www.postgresql.org/docs/11/sql-createfunction.html

Writing
SECURITY DEFINER
Functions Safely


...

$$  LANGUAGE plpgsql
     SECURITY DEFINER
     -- Set a secure search_path: trusted schema(s), then 'pg_temp'.
     SET search_path = admin, pg_temp;

Put the SET outside the function body.
