This test, in theory should change 0 columns, if none of the previous scripts have not used quoted values.
But because the initial [V1.5.2 script](https://github.com/cloudfoundry/uaa/blob/master/common/src/main/resources/org/cloudfoundry/identity/uaa/db/postgresql/V1_5_2__initial_db.sql) does mix case, we will use it just in case.
