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?
