I think this would be helpful to merge, or at least to have as a side note. I've wasted a while trying to get an in-memory database working for tests, only to find this and realise that I was missing poolclass=StaticPool!

I don't know whether this will be merged (seems to be open still?), but it has helped me. It saves a lot of clean up during and after tests.

@tiangolo would you like to merge?

Thanks @HarshaLaxman! 🚀

I've been wanting to update the docs about SQL to use SQLModel and re-use a bunch of those docs there. But for now, I'll take this. 🤓

And thanks everyone else for the comments and for letting me know that this is useful to you! 🍰
