The attached patch changes all implicit casts to text to assignment and
cleans up the associated regression test damage. This change has been
discussed for the longest time; I propose that we bite the bullet and
do it now.
The issue described in
<http://archives.postgresql.org/pgsql-hackers/2007-02/msg01729.php>
should also be fixed but can be considered separately later.
