Spring boot: H2 test database don't recognize "serial4"

Question

I'm using h2 as in memory in order to test a spring repository class. But when h2 try to create the table return:

org.h2.jdbc.JdbcSQLNonTransientException: Unknown data type: "SERIAL4";

The ddl of the table show that the id column is a serial4 datatype.

id serial4 NOT NULL

But h2 don't recognize that. The origina table is under postgresql.

There is any type of solution?

Thanks

UPDATE:

I've updated the applications.yaml of test enviroment, but the result is the same. Here's the updated yaml file:

spring:
  application:
    name: test_name
  jpa:
    database-platform: org.hibernate.dialect.H2Dialect
    show-sql: true
    properties:
      generate-ddl: true
      hibernate:
        ddl-auto: create
        format_sql: true
        jdbc:
          batch_size: 500
          lob:
            non_contextual_creation: true
  datasource:
    driver-class-name: org.h2.Driver
    url: jdbc:h2:mem:mydb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;DATABASE_TO_LOWER=TRUE;MODE=POSTGRESQL;INIT=CREATE SCHEMA IF NOT EXISTS test_schema\;
