title: Does spring.jpa.hibernate.ddl-auto=validate make changes in DB schema?
body: <p>On production environment I am using spring.jpa.hibernate.ddl-auto=validate but I found new columns are added in my production DB automatically. </p>
  
  <p>I have done a small POC with dummy application it is not adding a column on my local system.</p>
  
  <p>Can anyone help me understand what could be the issue with <code>spring.jpa.hibernate.ddl-auto=validate</code> property.</p>
  
  <p>Any help is appreciated. </p>
  
  <p>PFA I visited the documentation but did not get enough details:
