Beyond causing an "out of memory" error during the handshake, I fail to
see how there can be any problem.  palloc is considerably more robust
than malloc.

Perhaps you haven't tried.

It may indeed make sense to put a range check here, but I'm getting
tired of hearing the words "dos attack" applied to conditions that
cannot be exploited to cause any real problem.  All you are
accomplishing is to spread FUD among people who aren't sufficiently
familiar with the code to evaluate the seriousness of problems...
