I'd say, don't worry about it for now. Eventually, we will probably
want to replace the partitioning by CHECK constraint by some other
mechanism (like operator classes or something), at which point we will
want to come up with a more robust catalog representation. The mandate
at the moment, I suppose, is just to hide the existing functionality
behind a special purpose syntax to make the future internal changes
easier.
