Have CLUSTER ignore partitions not owned by caller
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.
