As the fine manual points out, the current scheme for managing
partitioned tables isn't intended to scale past a few dozen partitions.
I think we'll be able to do better when we have an explicit
representation of partitioning, since then the planner won't
have to expend large amounts of effort reverse-engineering knowledge
about how an inheritance tree is partitioned. Before that happens,
it's not really worth the trouble to worry about such cases.
