Databases have the same problems when disks fail, power goes out etc.

If you mean they have to solve the same problems with very careful design and programming, yes. It's non trivial. Even Postrgres had a correctness issue around fsync for nearly twenty years.

If you roll your own, that's very hard to get right. I wouldn't have confidence in such a system that I've built myself.
