Dependencies:

<dependencies>

        <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>

Properties short way:

spring:
  datasource:
    url: jdbc:postgresql://localhost:5432/custom_database
    username: postgres
    password: password
  # if you want your app to auto create tables on start:
#  jpa:
#    hibernate:
#      ddl-auto: create

And a little more advanced:

spring:
  jpa:
    properties:
      hibernate:
        jdbc:
          time_zone: UTC
  datasource:
    url: jdbc:postgresql://localhost:5432/custom_database
    username: postgres
    password: password
    hikari:
      connection-timeout: 30000
      maximum-pool-size: 100
      minimum-idle: 10
      idle-timeout: 60000
      max-lifetime: 120000
      auto-commit: true
