title: Liquibase is not creating database after setting createDatabaseIfNotExist=true
body: <p>I added database configuration in <code>build.gradle</code></p>
  
  <pre><code>liquibase {
     activities {
     main {      
        changeLogFile "${this.rootDir}/src/main/resources/changelog-master.xml"
        url "jdbc:postgresql://localhost:5432/test?createDatabaseIfNotExist=true"
        username "xxxx"
        password "xxxx"
  
       } 
    }
   runList = 'main'
  } 
  </code></pre>
  
  <p><code>createDatabaseIfNotExist</code> is set to true in the URL. </p>
  
  <p>When I start the server, it gives database does not exists. </p>
  
  <p>I want liquibase to create database if it doesn't exists.</p>
  
  <p>Any suggestions please</p>
