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.
