def METHOD_NAME(body: str) -> str:
    """
    Clean the given string so it can be passed into Postgres.
    For example, Django's Postgres backend will raise a "A string literal
    cannot contain NUL (0x00) characters" error if a string ever
    contains such characters, so this function strips them out:
        >>> clean_body('please email link \\x00 boop\\x00msn.com')
        'please email link \uFFFD boop\uFFFDmsn.com'
    """
    return body.replace("\x00", "\uFFFD")
