Someone already chimed in for SQLite, so worth mentioning that Python is hard typed, just dynamic. Everyone has seen TypeError; you'll get that even without hints. It becomes particularly obvious when using Cython, the dynamic part is gone and you have to type your stuff manually. Type hints are indeed hints, but for your IDE, or mypy, or you (for clarity).

It's a bit like saying C++ isn't typed because you can use "auto".

If I want to bother with a SQL database, I at least want the benefit of the physical layer compressing data to the declared types and PostgreSQL scales down surprisingly well to lower-resource (by 2025 standards) environments.
