I'm looking at a pg_stat_activity dump where there are a group of active
threads stuck for a long time in MessageQueueSend
7:52.394089+00 | IPC | MessageQueueSend | active |
| 27406510 | -5892847938856697008 | SELECT ....
Does this mean they are blocked on clients reading data or does it
represent something blocking on the server side?
Thanks
Ben
