The main patch is committed now. I think the pending item in this
thread is to conclude whether we need a storage or subscription to
disable/enable this feature. Both Andres and Onder don't seem to be in
favor but I am of opinion that it could be helpful in scenarios where
the index scan (due to duplicates or dead tuples) is slower. However,
if we don't have a consensus on the same, we can anyway add it later.
If there are no more votes in favor of adding such an option, we can
probably close the CF entry.
