For pgq questions. try the gthub page and raise an issue. Having said that, looking at: https://github.com/pgq/pgq/blob/master/functions/pgq.batch_event_sql.sql and https://github.com/pgq/pgq/blob/master/functions/pgq.ticker.sql It's pretty clear that they are not using listen/notify, but some kind of table/ticker based implementation. There used to be more information on the implementation on the old skytools page, but that page seems to have been retired. merlin
