| Yes, it appeared to be in a transaction. The pg_stat_activity.xact_start was before the query_start. Unfortunately, I don’t have the other queries. (I snapshot pg_stat_activity every minute, so it missed any prior queries to the blocker).

Hi chris,
Is this query in transaction block ? Forgot to mention, this is on PG 16.1

All,
We had an outage today that appears to have been caused by a query in "IPC:MessageQueueReceive” wait state blocking another query from completing a truncate.
Is there anyway to figure out what exactly it was waiting on other than an IPC message? I’m trying to get to the true root cause of our outage.
Thanks,
