The assumtion that char and varchar can be compared is gone. Any comparison
or in this case concatination between the two types needs to be explicitly
cast.
try
SELECT code::varchar || ' ' || diag::varchar, code
FROM dsm4
WHERE axis = 1
ORDER BY code;
Thanks

SELECT code || ' ' || diag, code

This worked on 6.3-7.3.1 now it dies with:
'unable to identify an operator || for types 'character' and 'character
varying'
What happened?????
