Avoiding increasing operational complexity is really important, but for pub/sub we are using Redis. While this does add complexity, it is very little, because it is incredibly easy to install and maintain.

Obviously you're in a better position to evaluate the trade-offs for your application than I am, so I'm not saying your decision is wrong, but this can potentially decrease availability if your application depends on both PostgreSQL AND Redis to be available to function.
