SpringBatch : Unable to detect database type - postgresql

Question

I am creating a very basic Hello World Spring Batch application in Springboot.
But springboot is not able to connect to Postgres database.
My postgres is running in docker locally.
Although same application is working with H2 database.
Is there any other property I am missing for Postgres?
Getting below error:

Answer 1

Application properties
spring.datasource.url=jdbc:postgres://localhost:5439/spring_batch
The database type should be postgresql, not postgres.
