Allowed values of rr:tableName include both schema-qualified names and unqualified names. Therefore there should be test cases that cover both of these options.

Having a single test case that uses a qualified name would be sufficient to cover this case.

If using unqualified names everywhere else increases compatibility with database engines then we should do it.
