basic optimizer support for k-NN searches

Details

    Description

      Optimizer has to use the k-NN capable vector index for queries like

      SELECT ... FROM table ORDER BY VEC_DISTANCE(col, const) LIMIT n

      That is

      • ORDER BY VEC_DISTANCE
      • one argument is a column of a table, the other is a constant
      • LIMIT
      • no WHERE clause
