ID:          syspriv.read-raw-pages
TITLE:       Check ability to get binary content of DB page by non-sysdba user who is
  granted with necessary system privilege
DESCRIPTION:
  Test uses ability to read binary content of DB page that is provided by FDB driver (see con.get_page_contents() call).
  We obtain content of page with ID=1 (this is PIP) and get its type (it must be 2).
  This action can be done by NON-dba user only if he has apropriate system privilege, otherwise FDB raises Python-related
  error. We catch this error in order to prevent failing of test with 'E' outcome and print text of exception.
