> Lots of good stuff in here, including much more support for using UUIDs as PKs. I missed this. Going through the changelogs the only thing I found is support case-insensitivity for pg UUID types. Is that what you meant? I really think that not supporting UUID PKs is one of biggest issues with Rails. You can go around it and maybe even use a gem for it, but that's still a bit risky.
