I think separate entries work for log_min_error_statement because the
error string and query are both long, and you can pretty much guess
which error goes with which query, and you are looking at errors, which
are pretty rare events, hopefully.

I think they fit pretty nicely on one line, and lot of folks want that
information.  I realize it looks like bloatware because it duplicates
some existing functionality, but I think it is a combination of duration
and statement output that can't be done easily separately.

Also, I don't see us combining any other log_* operations:
        #log_connections = false
        #log_duration = false
        #log_pid = false
        #log_statement = false
        #log_timestamp = false
        #log_hostname = false
        #log_source_port = false

You mean how are they passed to the client?  I assumed that would work
for pre-V3 clients.
