Re: Build a Java App with CockroachDB

Issue Description

In the hibernate.cfg.xml we specify org.hibernate.dialect.PostgreSQLDialect This has been deprecated.

Suggested Resolution

org.hibernate.dialect.PostgreSQL95Dialect should be used as CRDB advertises to clients that it is PostgreSQL 9.5 compliant.
