If a partitioned table has partitions owned by roles other than the owner of the partitioned table, don't include them in the to-be- clustered list. This is similar to what VACUUM FULL does (except we do it sooner, because there is no reason to postpone it). Add a simple test to verify that only owned partitions are clustered. While at it, change memory context switch-and-back to occur once per partition instead of outside of the loop.
