Thank you, very interesting read! They do raise a few good points where MySQL outperforms PostgreSQL. I suppose that's one of the trade offs between them, data safety vs. performance.

Well, it's also quite a misleading read as the numerous rebuttals will point out:

> Uber switched from Postgres to MySql.
really uber should not taken as an example, especially since they failed so hard with their databases in the past.
(I'm a Postgres fan, yes, but I think that there a valid reasons to migrate to MySQL (there are several other companies who use mysql, etc but Uber's stuff is just plain FUD))
If I remember right, though, mostly because their use pattern was more like a key value store, and MySQL worked better for that pattern.
