Zonky embedded database with Reactive Hibernate

Hi guys,

I am trying to connect a integration test with a embedded GitHub - zonkyio/embedded-database-spring-test: A library for creating isolated embedded databases for Spring-powered integration tests..
i am trying to test a simple repository created to query a embedded postgresql database but i would like to know the current capabilities that exist to configure persistence.xml to connect to this kind of database.
i am having this problem when i run the test:

Caused by: org.hibernate.HibernateException: could not determine Dialect from JDBC driver metadata (specify a connection URI with scheme ‘postgresql:’, ‘mysql:’,

Any suugestion to configure this stuff?
