I have a use case for having foreign tables as non-leaf nodes in a
partitioning hierarchy, namely geographic. One might have a table at
HQ called foo_world, then partitions under it called foo_jp, foo_us,
etc., in one level, foo_us_ca, foo_us_pa, etc. in the next level, and
on down, each in general in a separate data center.
Is there something essential about having non-leaf nodes as foreign
tables that's a problem here?
Cheers,
David.
