Goose를 사용하여 PostgreSQL 함수의 \'종료되지 않은 달러 인용 문자열\' 오류를 해결하는 방법은 무엇입니까?

CREATE OR REPLACE FUNCTION add_userlocation(user_id INT, location_id INT) RETURNS VOID AS
$BODY$
-- +goose StatementBegin
BEGIN
    LOOP
        UPDATE userslocations SET count = count+1 WHERE userid = user_id AND locationid = location_id;
    IF found THEN
        RETURN;
    END IF;
    BEGIN
        INSERT INTO userslocations(userid,locationid, count) VALUES (user_id, location_id, 1);
           RETURN;
       EXCEPTION WHEN unique_violation THEN
    END;
   END LOOP;
-- +goose StatementEnd
END;
$BODY$
LANGUAGE plpgsql;
