I have a plan but it's a future plan. This patch is for parallel
vacuum patch. As I mentioned at that thread[1], I'm focusing on only
parallel index vacuum, which would not require the relation extension
lock improvements for now. Therefore, I want to withdraw this patch
and to reactivate when we need this enhancement.
So I think we can mark it as 'Returned with feedback'.
