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.) regards, tom lane
