Prepare the postgres DB

The workshop id done using the PostgraseSample database: https://www.postgresqltutorial.com/postgresql-getting-started/postgresql-sample-database/

Create a Postgres instance and add the sample file

• a local version using docker
• a cloud instance for free: https://www.elephantsql.com/

Download the sample database: https://www.postgresqltutorial.com/wp-content/uploads/2019/05/dvdrental.zip

unzip the file and use the dvdrental.tar to intialize the db with the command:

pg_restore --host=lucky.db.elephantsql.com --username=suauakil --password --dbname=suauakil dvdrental.tar

On https://www.elephantsql.com/ the command should be run twice, it returns errors but the db will be initialized with the data required for the workshop.
