I agree. I'm in the process of reformulating this proposal from the
syntax, catalog and DDL -centric perspective and will re-incorporate
multi-level partitioning notion into it. It was a mistake to drop it.

I don't really understand why parallel query was pursued in small pieces, but partitioning needs to happen all in one huge patch. Wishing too many things is going to slow down this feature.
