I modified patch 1 a bit -- result attached. I would like to back-patch
this all the way back to 9.4, but there are a few conflicts due to
c29aff959dc so I think I'm going to do pg10 only unless I get some votes
that it should go further back. I think it should be fairly trivial to
resolve.
The other patch should be applied to master only IMO.
