What is the difference between org.hibernate.dialect.PostgresPlusDialect vs. org.hibernate.dialect.PostgreSQL9Dialect?
<p>I use Spring Boot 1.4.1.RELEASE, Hibernate, PostgreSQL 9.6.0.x . I see IntelliJ IDEA suggest 2 dialects:</p>

<pre><code># Hibernate config
#spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect
spring.jpa.database-platform=org.hibernate.dialect.PostgresPlusDialect
</code></pre>

<p>What is the difference between them?</p>
