I've tuned ~40 postgres instances, primarily using log_checkpoints and pg_stat_bgwriter, with custom RRD graphs. pg_buffercache does provide some valuable insights, and I know it's commonly suggested to check histogram of usagecounts, but I've never had any idea how to apply that to tune shared_buffers. Could you elaborate on what procedure you suggest ? Justin
