HAPI has released a latest docker image on 27-Feb-2023. In this version due to some upgrades on the hibernate dependencies, the earlier hibernate dialect setting spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL95Dialect is not working anymore. It results in the below error.

In the latest hapi release, the artifact ca.uhn.hapi.fhir:hapi-fhir has been upgraded to version 7.0.0. In this 7.0.0 version the HIbernate.version used in 6.4.1.Final. Support for the dialect org.hibernate.dialect.PostgreSQL95Dialect has been removed in this hibernate version and is replaced with org.hibernate.dialect.PostgreSQLDialect. We could have used this dialect instead, but hapi recommends using this
ca.uhn.fhir.jpa.model.dialect.HapiFhirPostgresDialect
