Hi all. I understand this can be a ridiculous question for most you. The very same query on the very same db shows very variable timings. I'm the only one client on an unpupolated server so I'd expect a rather constant timing. INstead for a while the query become very slooow and the CPU reached 60 to 70% and the time needed is about 1.5 minutes0. Again with just me on it. Normally the same query rises the usage to a mere 5% to 7% with timing with the tenth of a second. I have disable both the autovacuum and the "stats_start_collector" in the attempt to disable possibe reasons for slow down. No luck in this.
