Also, the NOTIFY wouldn’t significantly extend the lifetime or impact of the trigger.On Jul 17, 2019, at 1:26 AM, Dirk Mika <Dirk.Mika@mikatiming.de> wrote:We used a trigger that called pg_notify (https://www.postgresql.org/docs/9.5/sql-notify.html) and then had another
process that LISTENed for notifications.
What kind of process is this? I'm assuming that this is an application written in C.
The advantage of LISTEN / NOTIFY is only that the process which should process data does not have to do polling, but is notified when there is something to do.
