title: org.postgresql.util.PGobject not available in org.postgresql
body: <p>I'm using Spring boot 2.1.5.RELEASE and I have the following dependency in my pom.xml</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;org.postgresql&lt;/groupId&gt;
      &lt;artifactId&gt;postgresql&lt;/artifactId&gt;
      &lt;scope&gt;runtime&lt;/scope&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>But <code>org.postgresql.util.PGobject</code> is not found. In another non-spring boot project  I have the following dependency</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;org.postgresql&lt;/groupId&gt;
      &lt;artifactId&gt;postgresql&lt;/artifactId&gt;
      &lt;version&gt;42.2.5&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>and <code>org.postgresql.util.PGobject</code> is available for use.</p>
  
  <p>Any idea why <code>org.postgresql.util.PGobject</code> is not found in the spring boot project?</p>
