title: Liquibase + Hibernate rename column
body: <p>I'm using a H2 database to store my Data, and liquibase (with hibernate plugin) to check for differences between database and projet.</p>
  
  <p>suppose I have followign Code:</p>
  
  <pre><code>@Entity
  public class myEntity{
  
      @Column(name="val")
      private int value;
  
  }
  </code></pre>
  
  <p>The database is in place and already stores some data.</p>
  
  <p>Now when I rename the above Column i.e. from val to value and run liquibase:diff, the difflog says to drop the column "val" and add a column "value".</p>
  
  <p>Obviously this is not what I wanted, because all the data originally stored in the "val" column would be gone.</p>
  
  <p>Is there a way to tell liquibase that its not a new column, but an old renamed one? </p>
  
  <p>I want to run liquibase:diff and the generated diffLog should automatically contain the rename... tag for my Column, not an add.. and a drop.. one..</p>
