If you look at past Jepsen test mostly they fail, and sometimes they fail spectacularly. This is one of those things where if you don't have an automated test suite to continually verify correctness you will end up with bugs.

You can check out the other databases he has tested here: http://jepsen.io/analyses

That being said, none of the big players in sql are there, so you can't size it up against postgres or mysql.

Postgres has been analyzed, I'm not sure why it's not on that list.

Galera was tested - enabling MySQL to behave like a distributed database

isn't that because they are not distributed systems?
