Traditional log-level semantics aren't very rich. I think that's the real
source of this problem: "How do I get the info I need to tune auto-vacuum
without swamping my system with log IO". While the following isn't
production ready, it seems to have some really good ideas.


log4c is inspired by log4j, which seems to have become the defacto standard
tool for logging in the enterprise java world.
