  Failed to initialize JPA EntityManagerFactory: 
   Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

Good morning, I believe you will need to create in the properties file the path of the driver of the database you will use, I saw that you declared Postgres is Mysql, so in the application.properties file you will need to put so. spring.datasource.driver-class-name=org.postgresql.Driver. I hope it helps you. :)
