Looks like it should be referring to box_intersect(). Will fix the docs
--- thanks for catching this!

FWIW, I don't have a whole lot of confidence in the built-in geometric
functions. They started as an academic exercise (like the rest of
Postgres) but have not been wrung out the way the rest of the system
has. It seems like everyone who uses them finds more bugs. So use 'em,
by all means, but test before you trust.

You might also care to look at PostGIS, which has the intention of being
industrial-strength code. I'm not sure what their level of wrung-out-ness
really is at the moment, but at least there are people actively working
on that code.
