where name ilike 'savino del bene s%'
order by upper(cleanup(name));
If you are trying to get smarter than the collate, don't you think it would be a good idea to use C collate?
e.g. ORDER BY upper(name) COLLATE "C";
You can even use a cleanup like to convert things that you want to consider the same (as using unaccent). Although it would make harder to move with and without accent to the same place.
