I tend to agree with you but I haven't found any good way to put things in a queue from within postgres - from a trigger for instance. Doing so would open up a lot of possibilities - do you have any suggestions, even if its just for things to google?

I haven't personally used either of these, but they look interesting and I'm hoping to test them out at some point:

https://github.com/subzerocloud/pg-amqp-bridge

In theory, these let you use postgres NOTIFY to add messages to queues (which can be done from inside triggers).
