Hi pgsql-general,
I'm interested in writing a supervisory process that can insure worker processes are
running/spawn new ones if not. These workers will mainly be responsible for LISTENing to
the db, which is emitting triggered_change_notification s.
Is there any means to check a NOTIFY queue to see who or if anyone is LISTEN ing on it?

Regards,
You can look in the pg_listener table. The relname is the
Listen/notify code that you call and the listenerpid is the OS pid.
You can see more details of that in the pg_stat_activity
