Allow log_min_messages to be set per process type Change log_min_messages from being a single element to a comma-separated list of type:level elements, with 'type' representing a process type, and 'level' being a log level to use for that type of process. The list must also have a freestanding level specification which is used for process types not listed, which convenientely makes the whole thing backwards-compatible.
Some choices made here could be contested; for instance, we use the process type `backend` to affect regular backends as well as dead-end backends and the standalone backend, and `autovacuum` means both the launcher and the workers. I think it's largely sensible though, and it can easily be tweaked if desired.
