Load PostgreSQL Sample Database


Load PostgreSQL Sample Database

Summary: in this tutorial, we will show you how to load the PostgreSQL sample database into the PostgreSQL database server.

Before going forward with this tutorial, you need to have:

Load the sample database using psql tool

First, launch the psql tool.


Second, enter the account’s information to log in to the PostgreSQL database server. You can use the default value provided by psql by pressing the Enter keyboard. However, for the password, you need to enter the one that you provided during PostgreSQL installation.

Server [localhost]: Database [postgres]: Port [5432]: Username [postgres]: Password for user postgres:

Third, enter the following CREATE DATABASE statement to create a new dvdrental database.


PostgreSQL will create a new database named dvdrental.

Finally, enter the exit the command to quit psql:

postgres=# exit

Then, navigate the bin folder of the PostgreSQL installation folder:

C:\>cd C:\Program Files\PostgreSQL\12\bin

After that, use the pg_restore tool to load data into the dvdrental database:

pg_restore -U postgres -d dvdrental C:\sampledb\dvdrental.tar

In this command:

  • The -U postgres specifies the postgresuser to login to the PostgreSQL database server.
  • The -d dvdrental specifies the target database to load.

Finally, enter the password for the postgres user and press enter


It takes about seconds to load data stored in the dvdrental.tar file into the dvdrentaldatabase.
