OK, I see now, updated:
* Simplify integer cross-data-type operators
Email text is:
http://archives.postgresql.org/pgsql-bugs/2008-01/msg00199.php
So it seems that the problem with cross-type operators is not so much
having them as having incomplete sets of them. We could fix this case
either by adding int2 + int8 or by removing int4 + int8, and simplicity
would seem to argue for the latter.
