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 ?
