I think the refactoring that you proposed in the thread "Refactor to 
introduce pg_strcoll()." was on a sensible track.  Maybe we should try 
to get that done.  The multiple-ICU stuff is still experimental and has 
its own rather impressive thread, so I don't think it's sensible to try 
to sort that out here.
