I believe that the current design of partitioning is explicitly intended
to avoid the need for such a construct. It'd be absolutely disastrous
to have such a thing from many standpoints, including the breadth of
locking needed to work with the global index, the difficulty of vacuuming,
and the impossibility of cheaply attaching or detaching partitions.
In other words, this is a "feature" we do not want.
