It can be more complicated depending on your environment but I'd prefer instead to use a Pub/Sub pattern instead. You can have a generic topic if you want to model it like the generic table but it handles retries, metrics, scaling, long-running, etc all for you. If you are running in the cloud then Pub/Sub is something you don't need to maintain and will scale better than this solution. You also won't need to VACUUM the Pub/Sub solution ;)
