Huh?  The above is 100% fanciful; there was no code in libpq or anywhere
else that would have processed such a thing.

The bigger picture is that this patch is needed, not only for
walreceiver but for many other purposes --- the feature has been
requested repeatedly over the years and was already in the 9.1
commitfest queue.  We moved it up because it seemed fairly important for
walreceiver's purposes, but it would have gotten done in the very near
future anyway.
