A few years ago, I went through Slony's logging with a view to this very thing.
It was pretty fruitful in changing log levels for a lot of things, and actually
led to more things being logged 'always', as I noticed useful places to do
CONFIG level logging in the process.
But we were able to get things to the point where INFO logging provided
enough output most of the time.
Looking through the Postgres code base to this end seems likely to be
pretty useful, and I agree, it would need to be done holisticly.
