Hard to tell when you haven't provided a complete example.

This is my test case with constant string:

CREATE OR REPLACE FUNCTION syslog.new_event_action() RETURNS trigger

    LANGUAGE plpgsql

    AS $$

    BEGIN

        RAISE WARNING 'syslog.new_event_action() called.';

        PERFORM pg_notify('INSERTED', '');

        RETURN NEW;

    END

$$;

The warning is being logged.

In psql session 1, I run a LISTEN INSERTED;

In psql session 2, I run my INSERT (getting one row inserted)

In psql session 1, I run SELECT now(); do not get asyncronous notification.
