pl/pgsql in a script?

Is it possible to run pl/pgsql in a script, without putting it into a function? I need to run a one-time update to my db. I could easily create a function run it and then drop it, but I’m wondering if I can just skip the function creation... Here’s what I’m trying to do...

DECLARE

    emp RECORD;

    db_id INTEGER;

BEGIN

    db_id := get_db_id();

    FOR emp IN SELECT email, min(password_sha256) AS pwd, min(external_id) as ext_id FROM employees WHERE coalesce(email, '') != '' AND priv_admin_sign_in = true group by email

    LOOP

                PERFORM dblink_exec('dbname=system', 'insert into logins

                  (email, external_id, password_sha256, database_id)

                  VALUES ('''||emp.email||''', '''||emp.ext_id||''', '''||emp.pwd||''', '||db_id||');');

    END LOOP;

END;

$$ LANGUAGE plpgsql;
