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