I have a database that has started to constantly hang after a brief period of activity
looking at `select * from pg_stat_activity;` I roughly see the following each time:
process 1 | <IDLE>
process 2 | <IDLE> in transaction
process 3 | <IDLE> in transaction
process 4 | <IDLE>
process 5 | <IDLE>
process 6 | <IDLE>
process 7 | INSERT INTO table_a ........ RETURNING id
occasionally I'll see
process 8 | UPDATE table_b
Does anyone have tips on how I can troubleshoot this.
I was hoping there would be some way to show the history of the "<IDLE> in transaction" processes, but I couldn't find
them.
I was also wondering if the "RETURNING id" might have something to do with this.
I'd appreciate any pointers in trying to figure out what is causing this.
