Seems I forgot to commit locally before creating the patch... Here's
the actual patch I meant to attach earlier.

I've attached an updated patch which updates the regression test output of a recent commit to include the "Unique Inner" in the expected results.

I've also performed a pgindent run on the patch.

Tom, I'm wondering if you think you'll get time to look at this before the feature freeze?

David
