PostgreSQL is a very different beast to what it was 10 years ago. So for a while it didn't support use cases as well as various NoSQL/NewSQL databases. However, PostgreSQL has also been built by great bunch of developers who are happy to adapt and implement the new, instead of harping on about the past. So personally I adapt that advice to instead "use evidence to guide decisions".
