Tom Lane b663f3443b Add a bunch of pseudo-types to replace the behavior formerly associated
with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...
