in result sets is now case sensitive by default. SQLAlchemy for many years would run a case-insensitive conversion on these values, probably to alleviate early case sensitivity issues with dialects like Oracle and Firebird. These issues have been more cleanly solved in more modern versions so the performance hit of calling lower() on identifiers is removed. The case insensitive comparisons can be re-enabled by setting "case_insensitive=False" on create_engine(). [ticket:2423]
