Description:        citext not acting like case insensitive search
Details:

When we run the following query, we return no results.

Select citystateinfoid from iss.citystateinfo where cityname =
'JACKSONVILLE' and statecode = 'FL';

However this does work

Select citystateinfoid from iss.citystateinfo where cityname =
'Jacksonville' and statecode = 'FL'

The second query is how the data is actually stored.  I've already forwarded
our ddl to david wheeler.
