> We ran into a production issue during our maintenance window when I switched over LifeKeeper/PostgreSQL nodes from one to another.  We noticed that the database was 1000 times slower than it usually is, then realized that the log_min_messages setting was set to 'debug5' for no reason.

How was the postmaster started?  From memory, "-d5" on its command line
would do that, and would not have been overridable from postgresql.conf.
