It sounds like something that'd be useful to do on top of declarative
partitioning, once that is merged. Perhaps you could start by reading
and testing the declarative partitioning patch. That'll give you a
better idea of the practicalities of doing what you propose on top of
it, and give you an opportunity to suggest changes to the declarative
partitioning scheme that might make conditional truncate easier later.
