Yes, this message landed to pgsql-hackers well.
You have sent a message on Saturday evening. Why do you expect immediate answer? Please, be patient. In certain cases expecting answers within a week - is optimistic. It worth to invest some time to make your messages clear and precise to shorten reply time and avoid additional clarification roundtrips.
Did you submit your proposal to GSoC website? If so - mentors are not registered on that site yet.
Best regards, Andrey Borodin.
