Thanks for having a look at the patch.

I don't agree that this is full circle. My motivation for the
additional changes is the API cleanliness of the function you're
making extern. I mentioned this in my 2nd paragraph in [1]. I didn't
like that you wanted to make the external function populate an array
and a Bitmapset with the same information. I think just having the
Bitmapset is fine and the array adds needless overhead and confusion.

As for this being backpatched or not. For me, about 51% of me thinks
this is fine for a master-only fix.

Does anyone else have any thoughts about back-patching the fix?
