No, it's been kind of on the back burner.

I think the executor side of things is pretty straightforward. Where I'm
really uncertain is on the planner side of things.

To be honest I didn't follow at all what Tom was saying to do with the
equivalence classes. What it's doing now is basically just lying and saying
the child columns are equivalent to the parent columns -- I'm not sure what
the consequences of that are. Tom seemed to think that would be bad but I
don't see any real problems with it.
