This is a wire-protocol limitation; libpq is only the messenger.
So if we're going to document it, I agree that limits.sgml is the place.

(BTW, I'm not certain that PREPARE has the same limit.  It'd fall over
at INT_MAX likely, or maybe sooner for lack of memory, but I don't
recall that there's any uint16 fields in that code path.)
