Anyway, does it really matter? What is someone looking for a fast 'postgres' for analytics actually interested in?
(I didn't realise this was just an extension - in which case I'm amazed it's possible, but that obviously makes it an easy sell if you're already running pg. But if you're shopping about for managed solutions (which is obviously what Hydra wants to sell) with 'postgres' criterium, you're interested in the query language and maybe the wire protocol, surely?)
