2. Won't dissolving away "static" cause naming conflicts?
It might, yes. Those can be resolved, I think. I don't see a good reason why function names can't be unique across the source tree; at the very least, it means less irritation for anyone using tags.
3. Unit testing frameworks are best suited to component-based architectures, ISTM. I'm not sure that one would fit Postgres very well.
Can you elaborate?
Retrofitting unit testing is a lot harder than starting out doing it from day 1.
Granted, but I don't think that implies that retrofitting isn't worth the effort.
