Oh, just a bad error message eh?

[ Reads docs ... ] AFAICT, they've deprecated this in favor of some
other syntax that they introduced in 2.6, which was released in July 2012.
That makes it a nonstarter for us. We're not going to break PG altogether
for most people in order to hide a warning message on the bleeding edge
version.

(For comparison, I've got bison 2.3 on my Mac and 2.4.1 on my RHEL6
machine, both of which are pretty up-to-date platforms as such things
go. Some of the buildfarm machines are still running 1.875.)
