Hibernate + Postgres

(Obs.: já procurei no google e não encontrei solução satisfatória)
Estou fazendo uma pequena aplicação para aprendizado envolvendo Hibernate + Postgres …
E estou tendo o seguinte erro:

ERRO

Login

@Entity(name = "tbLogin")
@Table(name = "TB_LOGIN")
public class Login {
	@Id
	@Column(name = "CD_LOGIN", nullable = false)
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private Integer cdLogin;
	
	@Column(name = "EMAIL", nullable = false)
	private String email;
	
	@Column(name = "SENHA", nullable = false)
	private String senha;

//getters and setters

DAO

public class FacesDAO {
	
	protected static SessionFactory fabrica;
	
	Transaction transacao;
	
	Session sessao;
	
	public static SessionFactory getFabrica() {
		if (fabrica == null)
			fabrica = new AnnotationConfiguration().configure("hibernate.cfg.xml").buildSessionFactory();
		return fabrica;
	}
	
	public static void setFabrica(SessionFactory fabrica) {
		FacesDAO.fabrica = fabrica;
	}
	
	public void salvar(Object object) {
		try {
			sessao = getFabrica().openSession();
			transacao = sessao.beginTransaction();
			
			sessao.save(object);
			transacao.commit();
			sessao.close();
		} catch (Exception e) {
			if (transacao != null)
				transacao.rollback();
			e.printStackTrace();
		} finally {
			sessao.clear();
			sessao.close();
		}
	}
// e os demais métodos: excluir, recuperar objeto, recuperar lista ...

TesteLogin

public class TesteLogin {

	public static void main(String[] args) {
		try {
			FacesDAO dao = new FacesDAO();
			Login login = new Login();
			login.setEmail("[email removido]");
			login.setSenha("123");
			
			dao.salvar(login);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

O erro se dá ao salvar o login
Se alguém já teve alguma experiência parecida e puder me ajudar, desde já agradeço …
