This attribute provides all columns in this row to be referenceable. .. tip:: The :attr:`_postgresql.Insert.excluded` attribute is an instance of :class:`_expression.ColumnCollection`, which provides an interface the same as that of the :attr:`_schema.Table.c` collection described at :ref:`metadata_tables_and_columns`. With this collection, ordinary names are accessible like attributes (e.g. ``stmt.excluded.some_column``), but special names and dictionary method names should be accessed using indexed access, such as ``stmt.excluded["column name"]`` or ``stmt.excluded["values"]``.
