Hi 🙂
I tried using exact the same versions (I even deleted whole local cache for gradle) it doesn’t work.
All my changes are available on this branch:
https://github.com/Krzysztof1985/spring-boot3-jpa/tree/springBoot3_JDK17

I found also some old driver org.hibernate.dialect.PostgreSQL94Dialect, but it also doesn’t work.
Not sure but what do you think to update some migration guides.
I think the version PostgreSQL 11.0.0 is minimal required to be run with combo like:
Spring-boot3 + hibernate 6.

Regards
Krzysztof
