`index`

  `index` is the field whose scale will be retrieved.

  The possible values of `index` depend upon the value of ingres.array_index_start. If ingres.array_index_start is 1 (the default) then `index` must be between 1 and the value returned by ingres_num_fields(). If ingres.array_index_start is 0 then `index` must be between 0 and ingres_num_fields() - 1.
