the :order option should use LOWER on field by default otherwise will not order correctly

I've came to a problem with a different configuration of ORM. I was using PostgreSQL locally and remotely, the remotely ordered correctly but local not. 
My case was:

Trying to order something like: "ABC" and "Abc", the 'Abc' should go first than 'ABC'.


Does not make sense to find using LOWER and not ordering by default with LOWER.
