Hallöchen!

Yesterday I ported a web app to PG.  Every 10 minutes, a cron job
scanned the log files of MySQL and generated a plot showing the
queries/sec for the last 24h.  (Admittedly queries/sec is not the
holy grail of DB statistics.)

But I still like to have something like this.  At the moment I just
do the same with PG's log file, with

   log_statement_stats = on

But to generate these plots is costly (e.g. I don't need all the
lines starting with !), and to interpret them is equally costly.  Do
you have a suggestion for a better approach?

Have a look at http://pgfouine.projects.postgresql.org/
