Yes and no. Take the following with grain of salt as it is just my personal opinion/understanding. Only 1 or 2 points are actually from challenges I have run into. Restricting every query to a single core places an artificial CPU cap on a system that would otherwise be IO capped. Disks/storage is also getting faster (http://www.geek.com/chips/new-intel-storage-is-1000-times-faster-than-your-ssd-1629656/ http://www.geek.com/chips/new-intel-storage-is-1000-times-fa...). As analytics keeps gaining popularity, the need/desire to move more and more CPU bound processing to the data storage layer is increasing. And finally, PostgreSQL's advanced query planning/partitioning support would immensely benefit from being able to split partition queries into multiple process buckets.
