metadata = MetaData()

users = Table(
    "users", metadata,
    Column("id", Integer, Sequence("users_id_seq"), primary_key=True),
    Column("email", String(254), nullable=False, index=True, unique=True),
    Column("phone_number", String(32)),
    Column("password", String(128), nullable=False),
    relationship("note", back_populates = "notes"),


notes = Table(
