- `InfrastructureConfiguration` - sets up a R2DBC `ConnectionFactory` based on the R2DBC Postgres driver (https://github.com/r2dbc/r2dbc-postgresql[r2dbc-postgresql]), a `DatabaseClient` and a `R2dbcRepositoryFactory` to eventually create a `CustomerRepository`.

- `CustomerRepositoryIntegrationTests` - to initialize the database with some setup SQL and the inserting and reading `Customer` instances.
- `TransactionalService` - uses declarative transaction to apply a transactional boundary to repository operations.
