title: Is it possible to generate db.changelog-master.yaml on the basis of exsisting database?
body: <p>I would like to use db.changelog-master.yaml file to specify a database on Heroku. I created a relational database thanks to Spring Data JPA and I want to create db.changelog-master.yaml with the same structure as the relational database.</p>
  
  <p>Is there any way to generate the inside of db.changelog-master.yaml (liquidbase) on the basis of exsisting database?</p>
  
  <p><strong>(Update) Example solution for Postgres:</strong></p>
  
  <pre><code>liquibase --driver=org.postgresql.Driver --classpath=C:\Users\admin\postgresql-42.2.4.jar --changeLogFile=C:\Users\admin\db.changelog-master.yaml --url="jdbc:postgresql://localhost:5432/database" --username=postgres --password=postgres generateChangeLog
  </code></pre>
