title: Terraform-like auto-update db with liquibase/flyway, possible?
body: <p>We are still in the early phases of our project and we are building a database with several table.
  Both of the listed tools allow us to create some DDL/DML files and to track changes to the db. 
  Anyway this can be cumbersome when the structure is still not consolidated. </p>
  
  <p>Suppose I want to add a new column, or even delete a table: in both of the programs I have to create a new script with ALTER TABLE/etc. command and document the change.</p>
  
  <p>In terraform you just write your desired infrastructure and when you change the file by removing a node the tool only updates what is already there.</p>
  
  <p>Would it be possible to just list the tables in a file and when I, for example, delete a table definition the tool just updates the existing schema?
  Ditto if someone changes the schema by using another tool.</p>
