Are you sure they’re actually waiting? Don’t forget 10.5 will show the last query executed even if the connection is idle. I believe discard all would be the last command the pgbouncer would send to the database when the client is done as it resets the connection for the next client. So what you’re describing would seem to be expected behavior.
Try this to see if the queries are actually waiting: select * from pg_stat_activity where wait_event_type is not null or wait_event is not null; Scot Kreienkamp |Senior Systems Engineer | La-Z-Boy Corporate One La-Z-Boy Drive| Monroe, Michigan 48162 | Office: 734-384-6403 | | Mobile: 7349151444 | Email: scot.kreienk...@la-z-boy.com From: Nicola Contu [mailto:nicola.co...@gmail.com] Sent: Tuesday, October 16, 2018 8:12 AM To: pgsql-general@lists.postgresql.org Cc: Alessandro Aste <alessandro.a...@gtt.net> Subject: Re: Pgbouncer discard all Hello, is this normal? can anyone help?
