d„ Zy)r   aé  This class implements the Postgres MD5 Password hash, and follows the :ref:`password-hash-api`.

    It does a single round of hashing, and relies on the username as the salt.

    The :meth:`~passlib.ifc.PasswordHash.hash`, :meth:`~passlib.ifc.PasswordHash.genhash`, and :meth:`~passlib.ifc.PasswordHash.verify` methods all require the
    following additional contextual keywords:

    :type user: str
    :param user: name of postgres user account this password is associated with.
