Yes there is. If what you need is a database that will do pretty much anything well enough, then MSSQL and Oracle are going to manage it. They solve this by throwing money and hardware (more money) at the problem until it works. There's some clever stuff happening in there of course, but fundamentally they've just had much more engineering work over a long time. They can scale out more than Postgres can reasonably do. That said, Postgres is catching up, and arguably MySQL/MariaDB has always had a good story here. Scale-out options are improving all the time. The landscape has also changed in other ways too, now you can easily have a multi-terabyte Postgres cluster on a small number of machines serving large traffic volumes, and then put your "big data" into a more specialist database. The old world of shoving everything on MSSQL/Oracle may be a bit old-school.
