While not &#x27;vanilla&#x27; Postgres, this appears to be packaged reasonably as a PG extension. Since no vanilla PG code was changed, you should be able to upgrade PG without worry.<p>PG 9.5 introduces some support for parallelization along with custom scans. So this capability seems like a natural fit.<p>As for utility, big data queries tend to do heavy aggregations, and parallelization is a nice performance enhancement where it could be sorely needed.<p>Redshift has good name recognition, but under the covers, it&#x27;s ParAccel, which started with an early (8.2?) version of Postgres and modified it.
