Yes. In the case of a database, "safety" is safety from downtime, data loss, data theft. So companies want a database that is fault tolerant and secure.
> Postgres might be good enough for Imgur or Joe Bob's Bait Shack And Social Network, but neither of those is a bank, healthcare provider, or an entity capable of ordering an air strike.
Banks and healthcare providers strike me as far more insecure than tech companies, and especially more insecure than the large computing platforms like EC2, Google Cloud, etc. Any cloud can host a postgres database, and many of them offer database-specific services.
Oracle is competing not just with Postgres, but with literally every other database offering, many from leading tech companies.
The cloud extracts value by utility billing a large customer base. Oracle extracts value by overbilling a small customer base. Which model seems more sustainable? Eventually EC2, Google Cloud, etc will overtake Oracle completely. Maybe if Oracle is lucky they can provide the overpriced consultants to manage their client's EC2 boxes.
