Good morning,
This week we've noticed that we're starting to see spikes where COMMITs are taking much longer than usual. Sometimes, quite a few seconds to finish. After a few minutes they disappear but then return seemingly at random. This becomes visible to the app and end user as a big stall in activity.
How are you monitoring the COMMIT times? What do you generally see in pg_stat_activity.wait_event during the spikes/stalls?
