I was in an infinite loop within the Trigger. Here is how I fixed the problem. Thanks to:

The Trigger DDL:
CREATE TRIGGER firefly_new_geom
AFTER INSERT OR UPDATE
ON public.entries FOR EACH STATEMENT
EXECUTE PROCEDURE public.firefly_addupdate_creategeometry();
The Function:
BEGIN
IF pg_trigger_depth() <> 1 THEN
RETURN NEW;
END IF;
UPDATE entries SET geom = ST_SetSRID(ST_MakePoint(longitude,latitude),4326);
return new;
END;
