I think 100TB deployments is a very high bar you've set for postgres. I think the one place NoSQL databases continue to serve (and where My/Postgresql don't) are highly available, sharded deployments - and people are running into the issue at the 10s of TBs (I can't imagine you'd want 5TB+ of data served from a single node - AWS largest SSD instance would be 6.4TB in RAID0, and serving your database off a single large RAID0 already sounds like a bad idea). Not to say people aren't running these types of Postgres clusters, but its something not easily done. I think the anti-SQL sentiment is a very MongoDB-esque thing, in that MongoDB tried to replace everything. Most of the other popular NoSQL solutions have very clear and cut use cases, and are pretty upfront about selecting the right database.
