Can you please explain what that means? What is "dated code", how do you 
recognize it, and why does it make it difficult to work with?

Hmm. If setting up postgres is already considered a burden, I guess
I understand the problem. However, dependency-wise, I'd argue that
PyPI fares much better than many of the packages on PyPI. It's list
of dependencies is really short.
