- case_sensitive=(True|False) setting removed from schema items, since

    checking this state added a lot of method call overhead and there was
    no decent reason to ever set it to False.  Table and column names which are
    all lower case will be treated as case-insenstive (yes we adjust for
    Oracle's UPPERCASE style too).
