keep the default database instance postgres and create a dedicated DB instance shop_db for the application, see init.sql for the creation of this shop_db instance.

Create the shop_db DB instance, WHERE NOT EXISTS is not needed with the ephemeral containerized PostgreSQL instance but it's a PostgreSQL community best practice

Ditto, IF NOT EXISTS is not actually needed with ephemeral container but it's a PostgreSQL community best practice
