I manage Oracle, MySQL and, Postgresql (and even one SQLite, but "manage" doesn't quite describe the job).

Postgresql and MySQL are about the same complexity to manage: it's easy. Even compiling Postgresql is quick and trivial.

But Postgresql has a lot of features that make it the best database for an enterprise environment, especially FDW. Oracle has HS, but it is slow and not very reliable.

Overall, I'd say Postgresql and MySQL take hours of my time yearly. Oracle takes months of my time each year. SQLite doesn't take any time, but its use is limited.

I fully agree, but i slightly prefer postgresql over mysql due to their licensing

We only ever use MySQL if some software requires it.
