Here is a revival of this patch. This is Andreas Karlsson's v4 patch
(2017-11-01) with some updates for conflicts and changed APIs.
AFAICT from the discussions, there were no more conceptual concerns with
this approach. Recall that with this patch REINDEX CONCURRENTLY creates
a new index (with a new OID) and then switch the names and dependencies.
I have done a review of this patch and it looks pretty solid to me.
