I mean they literally list the per second numbers a couple paragraph down:

>Our databases were serving around 2 million requests per second (in this screenshot.)

I doubt pgsql will have fun on mid-range hardware with 50k writes/sec, ~2 million reads/sec and 4 billion additional rows per day with few deletions.

actually 'few deletions' and 'few updates' is basically the happy case for postgres. MVCC in a append only system is where it shines. (because you generate way less dead tuples, thus vacuum is not that big of a problem)
