Well, this is PostgreSQL, an extensible database, so the answer, to me,
is to implement it with a simple set of UDFs in userland as a proof of
concept. much like the materialized views recently discussed here.
After that, if someone thinks the basic concept is sound, it should get
migrated into the backend.

Sure, I'd love that too. But I think it's a bit too far ahead of the
game right now.

I would imagine that both might be saved by the same task. i.e. if
indexes and triggers could span across multiple tables etc... then
partitioned tables would be a pretty simple view creation.
