From 6c412f0605afeb809014553ff7ad28cf9ed5526b Mon Sep 17 00:00:00 2001

Subject: Change CREATE TYPE to require datatype output and send functions to
 have only one argument.  (Per recent discussion, the option to accept
 multiple arguments is pretty useless for user-defined types, and would be a
 likely source of security holes if it was used.)  Simplify call sites of
 output/send functions to not bother passing more than one argument.
