Hibernate generation Id to postgreSQL

Hi,

I'm trying to implement a id generator in Hibernate, but I'm having a problem. Hibernate doesn't seems to reset the counting when the id is generated. For example:

1 - In PostgreSQL I have a table (that entries were done with Hibernate script):

carId|car_description

1|john

2|mike

3|Peter

2 - Now, I clean the table, and next time I insert a new value on car_description, when I think that hibernate catch the min value(0 because the db is empty), it inserts the last value created (saved in memory perhaps).

carId|car_description

4|Michael

My class is:

@Entity @Table(name="tb_career") public class Career implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="seq_career") @SequenceGenerator(initialValue = 1, allocationSize = 1, name = "seqcareer", sequenceName = "seqcareer")

@Column(name="car_id", unique=true, nullable=false)
private Integer carId;
@Column(name="car_description", length=255)
private String carDescription;
//bi-directional many-to-many association to Course
@ManyToMany(mappedBy="tbCareers")
private List<Course> tbCourses;

Kind Regards! Thanks!
