I asked why such an index doesn't exists already. I guess that answers it. I definitely don't want to push for supporting that, especially not knowing what it entails.

I'd consider a duplication here a serious bug. That is pretty much catalog corruption. Having two children within a single child table sounds like it would break a lot of things.
That being said this function is hardly performance critical. I don't know whether throwing an elog indicating what's going wrong here would be worth it.
