For these specifically? Way easier than rabbitMQ. I love rabbitmq. It's an amazing technology, and if you need a high throughout message bus, it's still a better goto. But.. it does require quite a lot of expertise and know how to operate. Paged at 2am, you will likely get very frustrated.
Pgmq though, is "just a bunch of tables". It's going to be a lot easier to figure out what's going on. You already understand transactional DBs.
Unless of course, you already know how to operate rabbitmq.
