Implementing standards is always a goal of the PostgreSQL community, but
this is a very large patch arriving very late in the release cycle with
no prior discussion.

That the patch proposed follows a standard which will not be available
to the majority of reviewers is very worrisome, let alone the sheer
size.  While much of the code is new, I see many changes to core data
structures that could very easily be destabilizing.

I propose we move this patch to the 2017-07 CF so further development
and review can be done without haste and as the standard becomes more
