       * 
       * The fix is two parts.
       * 
       * First, when asking for the first column value twice from a cursor-fetched
       * row, the driver didn't re-position, and thus the "next" column was
       * returned.
       * 
       * Second, metadata statements and internal statements the driver uses
       * shouldn't use cursor-based fetching at all, so we've ensured that
       * internal statements have their fetch size set to "0".
