As for why you don't see long durations with EXPLAIN ANALYZE, here's a possible explanation: "ordinary" updates of the same record might happen close together because that's how the application works, but by the time you run EXPLAIN ANALYZE no other transactions are updating that record so the update executes immediately. -- Michael Fuhr
