      Remove security vulnerabilities that allowed connected users
      to read backend memory (Tom)
     </p><p>
      The vulnerabilities involve suppressing the normal check that a SQL
      function returns the data type it's declared to, and changing the
      data type of a table column (CVE-2007-0555, CVE-2007-0556).  These
      errors can easily be exploited to cause a backend crash, and in
      principle might be used to read database content that the user
      should not be able to access.
