I would observe that not requesting a revert would be inconsistent
against all other situations I have seen or been involved with.

Stephen has acted against explicit requests not to commit. I think
Robert should apply more care about issuing lock instructions, since
the concurrency of our community is important, but nonetheless, an
explicit request was made and that should be honored, even if it does
very quickly get re-committed.

My major reason to revert is the following: the documentation contains
no examples of real world usage, making the feature essentially
unusable out of the box. I attended Stephen's talk at PostgesOpen and
even that didn't contain real cases either, leaving me to ask
questions about stuff I thought I knew. This would be sufficient for
me to reject commit of any other patch, so it is sufficient reason
here also. Yeb can supply a useful real world case if there is some
restriction on explaining what this might be used for.

Stephen, I want this patch in 9.5 and I would very much like to see it
go in before Oct 31. But please follow consensus, revert the patch
now, address the minor issues as requested and then ask for re-commit
later, as you should have done in the first place.
