Suggested change

	values["hwm_column"] = Column(name=hwm_column) # type: ignore
	values["hwm_expression"] = hwm_expression
	dialect = connection.Dialect
	dialect.validate_hwm_column(connection, hwm_column) # type: ignore
	dialect = connection.Dialect
	dialect.validate_hwm_column(connection, hwm_column) # type: ignore
	values["hwm_column"] = Column(name=hwm_column) # type: ignore
	values["hwm_expression"] = hwm_expression

я бы сделал так, а то странно проводить валидацию после присвоения в values
