Looks good to me. Most of the comments are minor or questions. The license/version this was taken from should probably be stated.

I think you should be able to get away with a reference here.

Not sure what you mean with that. Replacing the Arc with a &?

I don't think there's much value in that as the Database struct needs to have an Arc anyways.

What's in this pull request?
Adds detailed metrics to the database crate – similarly to how
rethis doing it.This currently uses the
metricscrate, which is not compatible with ourprometheus_clientcrate.I implemented a connection between these two but it is not really nice. Thus, I'll also open an issue to improve this situation at a later point.
