Every time some production environment can be simplified, it is good news in my opinion. The ideal situation with Rails would be if there is a simple way to switch back to Redis, so that you can start simple, and as soon as you hit some fundamental issue with using SolidQueue (mostly scalability, I guess, in environments where the queue is truly stressed -- and you don't want to have a Postgres scalability problem because of your queue), you have a simple upgrade path. But I bet a lot of Rails apps don't have high volumes, and having to maintain two systems can be just more complexity.
