customer reported issue with extraction of his procedure:

CREATE OR REPLACE PROCEDURE "nulla"() 
  RETURNS INTEGER 
  EXECUTE AS OWNER 
  LANGUAGE NZPLSQL 
  AS 
    BEGIN_PROC 
      BEGIN 
        return(1); 
      END 
    END_PROC
GO

It would appear that the objType string is stored as 'procedure' in customers catalog table.  A non-modified catalog table would store this string as 'PROCEDURE' but the catalog data can be modified.  We need to enhance extraction so that modification to the catalog tables in this way will not affect our extraction.  Data is still case sensitive.
