Problem to save with hibernate, type checked is different than expected

I'm having a problem saving two tables ( @OneToOne ) to the database using Hibernate. Using weak relationship entities (person, address).

Errors displayed on the console:

  

Initial SessionFactory creation failed.org.hibernate.HibernateException: Wrong column type in public.citizen for column neighborhood_id. Found: int4, expected: bytea   Exception in thread "main" java.lang.ExceptionInInitializerError       at zup.model.utils.HibernateUtil (HibernateUtil.java:29)       at zup.business.AbstractBusiness.save (AbstractBusiness.java:25)       at zup.business.CitizenBusiness.main (CitizenBusiness.java:131)   Caused by: org.hibernate.HibernateException: Wrong column type in public.citizen for column neighborhood_id.

My model class:

//pacote

//named queries

public class Citizen implements Serializable/*, Comparable<MessageModel>*/{
    private static final long serialVersionUID = 1L;

    @Override

}

The second class to set the values as a foreign key in the class mentioned above:

package zup.bean;

import java.io.Serializable;

import javax.xml.bind.annotation.XmlRootElement;
import javax.persistence.Entity;
import javax.persistence.OneToOne;
import javax.persistence.Table;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Id;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Column;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

import org.hibernate.validator.constraints.NotEmpty;

import zup.messages.IMessages;

@Entity
@Table(name = "neighborhood")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Neighborhood.findAll", query = "SELECT c FROM Neighborhood c ORDER BY c.neighborhood_name"),
    //@NamedQuery(name = "Neighborhood.findByNeighborhoodId", query = "SELECT c FROM Neighborhood c WHERE c.NeighborhoodCPF = :NeighborhoodCPF"),
    @NamedQuery(name = "Neighborhood.findByName", query = "SELECT c FROM Neighborhood c WHERE c.neighborhood_name = :neighborhood_name")})

public class Neighborhood implements Serializable{

private static final long serialVersionUID = 1L;

    //-------------------------------------------------------------------------------
    //vari�veis e suas especifica��es
    @Id
    //@OneToOne( mappedBy="neighborhood_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "neighborhood_id")
    private int neighborhood_id;

    @NotEmpty(message = IMessages.NULL_FIELDS)
    @Size(min=3, max=60)//lembrando que nas especifica��es at� agora o m�nimo ainda n�o foi estipulado
    @Column(name = "neighborhood_name")//por conven��o estou colocando o valor que repassaram para o front-end
    private String neighborhood_name;

    //--------------------------------------------------------------------------------
    //metodos privados
    public String getNeighborhood_name() {
        return neighborhood_name;
    }

    public void setNeighborhood_name(String name) {
        this.neighborhood_name = name;
    }

    public int getNeighborhood_id() {
        return neighborhood_id;
    }

    //---------------------------------------------------------------------------------
    //construtores
    public Neighborhood(){
    }

    public Neighborhood(String name){//lembrando esse construtor recebe apenas o nome porque o id � auto incrementado
        this.neighborhood_name = name;
    }
}

And the test part I'm using to test my inserts in the database:

public static void main(String[] args) throws HibernateException, SQLException {

    Neighborhood n = new Neighborhood("Carajás");
    String data = "ainda sem caminho para a foto";
    byte[] photo = data.getBytes();
    NeighborhoodBusiness nb = new NeighborhoodBusiness();
    nb.save(n);

    Citizen s = new Citizen();
    s.setNeighborhood(n);
    //int a = s.getNeighborhood().getNeighborhood_id();
    //System.out.println(a);
    //System.out.println("*-----------------------------*");
    Citizen c = new Citizen("Patrocínio", "b", "12345678912", "Rafael", photo, "34383156899", "[email protected]",  "Avenida Brasil", 611);
    //Citizen c = new Citizen("12345678912", "Rafael", "34383156899", "[email protected]", "Patrocínio", "Avenida Brasil", 611, "b", photo);

    CitizenBusiness cb = new CitizenBusiness();
    cb.save(c);
    System.out.println(cb.findByCPF("12345678912").getcitizen_cpf());
    System.out.println(cb.findByEmail("[email protected]").get(0).getEmail());
    //System.out.println(cb.findBy("12345678912").getCitizenCPF());
    System.out.println(cb.findByName("Rafael").get(0).getName());
    //System.out.println(cb.findByCPF("12345678912").getCitizenCPF());  

}
