Postgres ?

[JoseRFJuniorLLMs]

Can this project be used for postgres?

Of course. This project uses H2, a relational in-memory database, but you only need to configure Spring Boot to work with PostgreSQL (see this https://dzone.com/articles/configuring-spring-boot-for-postgresql, for example). I don't think any modification to the code is needed.
