Update : Amazon Redshift announces support for uppercase column names

You can now specify whether column names returned by SELECT statements are uppercase or lowercase. With this feature, you can now set a session-based parameter to enable your case-sensitive applications to easily query Amazon Redshift. For more information, see describe_field_name_in_uppercase in the Amazon Redshift Database Developer Guide.
