What issue are you having? I'd imagine you have a race condition on the insert into hometowns, but you'd have that same race condition in your app code using a more traditional 3 query version as well. I often use CTEs like this to make things atomic. It allows me to remove transactional code out of the app and also to increase performance by reducing the back-and-forth to the db. http://omniti.com/seeds/writable-ctes-improve-performance
