If it does, then my review comments to Kedar still apply:
* why do we want another catalog table? what's wrong with pg_inherits?
It might need additional columns, and it certainly needs another index.
* We need an internal data structure (discussed on this thread also).
Leaving stuff in various catalog tables would not be the same thing at
all.
