If you include spring-boot-starter-cloud-connectors as a dependency, then Spring Cloud Connectors will attempt to create the java.sql.DataSource bean necessary to connect to the database. Connectors does this by looking for a service binding that has certain characteristics. The No unique service matching interface javax.sql.DataSource found message means that Connectors couldn't find a service binding of the appropriate type.

If you want to use Connectors as in that sample app then you will need to create a user-provided service instance with the details of the Postgres connection and bind that service instance to the app.

Alternatively, you could remove the spring-boot-starter-cloud-connectors dependency and instead configure the database connection using spring.datasource properties in application.yml.

These options are explained in more detail in a blog post.
