    construct.

    .. container:: inherited_member

        The :func:`sqlalchemy.dialects.postgresql.insert` function creates
        a :class:`sqlalchemy.dialects.postgresql.Insert`.  This class is based
        on the dialect-agnostic :class:`_sql.Insert` construct which may
        be constructed using the :func:`_sql.insert` function in
        SQLAlchemy Core.

    The :class:`_postgresql.Insert` construct includes additional methods
    :meth:`_postgresql.Insert.on_conflict_do_update`,
    :meth:`_postgresql.Insert.on_conflict_do_nothing`.

        PG's ON CONFLICT clause allows reference to the row that would
        be inserted, known as ``excluded``.  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"]``.   See the docstring for
            :class:`_expression.ColumnCollection` for further examples.

        .. seealso::

        Specifies a DO UPDATE SET action for ON CONFLICT clause.

        Either the ``constraint`` or ``index_elements`` argument is
        required, but only one of these can be specified.

        :param constraint:
         The name of a unique or exclusion constraint on the table,
         or the constraint object itself if it has a .name attribute.

        :param index_elements:
         A sequence consisting of string column names, :class:`_schema.Column`
         objects, or other column expression objects that will be used
         to infer a target index.

        :param index_where:
         Additional WHERE criterion that can be used to infer a
         conditional target index.

        :param set\_:
         A dictionary or other mapping object
         where the keys are either names of columns in the target table,
         or :class:`_schema.Column` objects or other ORM-mapped columns
         matching that of the target table, and expressions or literals
         as values, specifying the ``SET`` actions to take.

         .. versionadded:: 1.4 The
            :paramref:`_postgresql.Insert.on_conflict_do_update.set_`
            parameter supports :class:`_schema.Column` objects from the target
            :class:`_schema.Table` as keys.

         .. warning:: This dictionary does **not** take into account
            Python-specified default UPDATE values or generation functions,
            e.g. those specified using :paramref:`_schema.Column.onupdate`.
            These values will not be exercised for an ON CONFLICT style of
            UPDATE, unless they are manually specified in the
            :paramref:`.Insert.on_conflict_do_update.set_` dictionary.

        :param where:
         Optional argument. An expression object representing a ``WHERE``
         clause that restricts the rows affected by ``DO UPDATE SET``. Rows not
         meeting the ``WHERE`` condition will not be updated (effectively a
         ``DO NOTHING`` for those rows).
