• H2 syntax: https://hnygard.github.io/eva-admin-spring-boot-hacktogether/create.sql
• Postgresql syntax: https://hnygard.github.io/eva-admin-spring-boot-hacktogether/create-postgresql.sql
• https://hnygard.github.io/eva-admin-spring-boot-hacktogether/tables.html

• Start up: ./mvnw spring-boot:run (or run H2Application)
• Open http://localhost:8090/h2-console/
• Connection string: jdbc:h2:mem:db
• Username: sa
• Password: sa

• Start container with Postgres and Adminer (admin tool): cd docker-posgres; docker-compose up;
• Database should start up and Adminer available on http://localhost:8091/ (system: PostgreSQL, server: eva-postgres db: evaadmin, user: evaadmin, pass: evaadmin)
• Run PostgresqlApplication

Database should now be filled up with tables. The create-postgresql.sql contains the create statements.
