No suitable driver found for jdbc:pstgresql://localhost:5432/hibernatedb - postgresql

Question

I am getting this error. Tried two jar files into src folder, project folder etc too. Please check and help.
Tried Hibernate 3.6.4 and 5.4.2 both in different projects.

My hibernate configuration file looks like:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database Connection Settings
-->
<property name="connection.driver_class">org.postgresql.Driver</property>
<property name="connection.url">jdbc:pstgresql://localhost:5432/hibernatedb</property>
<property name="connection.username">admin</property>
<property name="connection.password">admin</property>
<!-- JDBC Connection pool (use the build-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<!-- Disable Second level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

<property name="hbm2ddl.auto">create</property>
<!-- Names the annotated entity class -->
<mapping class="org.SecondHibernateProject.dto.UserDetails" />
</session-factory>
</hibernate-configuration>
And the Main Java Class is as below:
package org.vishal.hibernate;
import org.SecondHibernateProject.dto.UserDetails;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;;
public class HibernateTest2 {
public static void main(String[] args) {
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("First User");
SessionFactory sessionFactory=new Configuration().configure().buildSessionFactory();
Session session= sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
}
}

Could you please refer the given steps to fix this issue.
To download the PostgreSQL jar from the given path as per version.
https://jdbc.postgresql.org/download.html
Add the jar to the project by using "external jar" option in eclipse.
Verify the classpath and URL path of PostgreSQL DB.
Make sure that the "hibernate.cfg.xml" file should be placed at the root of "src"
folder if you are using given code for reading this file.
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
If the "hibernate.cfg.xml" located at a different location then read this file from the given path.
SessionFactory sessionFactory = new Configuration().configure("/path/to/hibernate.cfg.xml").buildSessionFactory();
