BTree space reservation is more complicated.
Do you need to pre-reserve the space for b-tree? I think you can just
split it at upgrade, in the new version. The problem with doing that for
heaps is that to move a heap tuple you need to update the index
pointers, but for indexes there's no such restriction.
The problem is that I need to know parent and modify parent as well. But you
don't know what is your parent node. You need to know root and go from root.
It is why I think that it is not doable online.
Correct me if I'm wrong.
thanks Zdenek
