I know that is possible via EXPLAIN and EXPLAIN ANALYZE to get planned and actual time for one query - but no results.
I am looking for information like: "to do this query, I had to": - read x <units> from disk/os.cache - get n <units> from my own buffers - do n1 comparisons of strings - do n2 comparisons of inet - sort n3 tuples via xxx-sort - write z pages to disk ... And I want to use the results as normal - so to say, have a logging "what is the database really doing with all my hardwar" during normal operations. Are those information available somewhere? Something like pg_buffercache on steroids. Something like the windows performance-monitor is logging for the whole system.
