Attached is a demo patch that adds a placeholder %b for log_line_prefix
(not in the default setting) that contains the backend type, the same
that you see in pg_stat_activity and in the ps status. I would have
found this occasionally useful when analyzing logs, especially if you
have a lot of background workers active. Thoughts?
