Yes same hierarchies will work but mainly because one has to add
partitions themselves to publication currently. I guess that's the
limitation we might have to live with in 10 as adding the whole
partitioned table should probably work for different hierarchies when we
enable it and I am not quite sure that's doable before start of the CF
at this point.
