Excellent start, added my initial review for you. Based on how that progresses we might be ready for a final review already.

Looks good. Can you also as part of this PR try to remove deadpool in the rama-cli fp code. Or what is your opinion on that? Seems to me like an excellent practical use case that also is a first good demonstration of this code in a real setting?

Not sure if this belongs in this PR, removing deadpool is one thing, but rama-cli also uses deadpool_postgres. These two combined actually do quite a lot of logic

I tend to call these kind of things maybe_with_x and also provide a version with_x without the Option wrpaper, and even a set_x version for &mut self (without the option wrapper).

Mostly is looking good. I do agree that removing postgres-deadpool is probably out of scope for this PR.

Still, might be nice to add an example in /examples that is also tested.
