And I would re-iterate that just because something isn't in mainline, doesn't mean it's not possible. Did you know that Pg didn't have native partitioning until Pg10? Somehow we managed to do partitioning before then.
I don't buy the argument that you need to ship broken features just to have them; Pg doesn't include it into base until it's a /good/ solution which is well engineered and has appropriate toggles. That is not a horror story.

I shipped a game which had similar CCUs (within the order of magnitude) and I can confirm that you can't do it with one postgresql machine, or.. actually you could but we chose to fsync() constantly to prevent corruption from ever happening and remove the RAID cache.. but you can shard on top of your database solution too.
