Yeah. I rather doubt that we want this mechanism to be very closely
tied to the existing inheritance features. If we do that, we are
going to need a boatload of error checks to prevent people from breaking
partitioned tables by applying the sort of twiddling that inheritance
allows.

Of course, the more general you make it, the more likely that it'll be
impossible to optimize well.
