@evan Yah, I mean this certainly falls under the "unprovable marketing claims" column in my books, but there are indeed some pretty great features in pgsql all under one roof:
- You can make NoSQL-style queries with JSON columns
- You can do some pretty reliable full-text search
- Their pub-sub story is really strong.
In my opinion, you can replace a lot of systems with pgsql if you're at a smaller scale.
Of course, it has it's limitations and isn't a panacea.
