title: PostgreSQL + Openshift: Possibly the wrong driver for the given database URL?
body: <p>I am trying to run the liquibase update from <code>Openshift</code> machine that I have. It looks like  </p>
  
  <pre><code>&gt; java -jar ~/.m2/repository/org/liquibase/liquibase-core/3.1.1/liquibase-core-3.1.1.jar --driver=org.postgresql.Driver --classpath=wildfly/standalone/deployments/ROOT.war --changeLogFile=liquibase/changelog.xml --url="jdbc:$OPENSHIFT_POSTGRESQL_DB_URL/mydb" --username=$OPENSHIFT_POSTGRESQL_DB_USERNAME --password=OPENSHIFT_POSTGRESQL_DB_PASSWORD update 
  </code></pre>
  
  <p>and I see the following error  </p>
  
  <pre><code>Liquibase update Failed: liquibase.exception.DatabaseException: liquibase.exception.DatabaseException: Connection could not be created to jdbc:postgresql://admin:29asDVjpFxYl6@127.8.201.2:5432/mydb with driver org.postgresql.Driver.  Possibly the wrong driver for the given database URL
  </code></pre>
  
  <p>What is going wrong here?  </p>
  
  <p>I am using the following <code>postgreSQL</code> dependency  </p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;postgresql&lt;/groupId&gt;
      &lt;artifactId&gt;postgresql&lt;/artifactId&gt;
      &lt;version&gt;9.1-901-1.jdbc4&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
