I'm confused. Of course it's true to some degree that having a global index "defeats the purpose" of having a partitioned table. But only to a degree. And for some users it will make the difference between using partitioning and not using partitioning -- they simply won't be able to tolerate not having it available (e.g. because of a requirement for a unique constraint that does not cover the partitioning key). -- Peter Geoghegan
