I like the idea a lot. I'm not so sure about the approach.

How will this play with syslog? csvlog? etc?

I wonder if a level of indirection is appropriate here, where extensions
(or postgres subsystems, even) provide a log stream label. Then the logging
backed takes care of using that appropriately for the logging mechanism in
use; for logging to file that'd generally be separate files. Same for
CSVlog. Other mechanisms could be left as stubs initially.

So the outcome would be the same, just without the assumption of specific
file name and output mechanism baked in.
