Aim is to move my database currently existing in oracle to postgresql.  
  
I have created schema in oracle called as information\_schema.There some tables are there(around 9-10)  
I have a postgresql where I have the same schema called as information\_schema(currently empty).  
  
I did a diff btween two schema and tried to generate a merge sql but generated sql contain sql for sequence of oracle,it didint generated create table sql for all the tables present in oracle schema.  
  
How can I move oracle schema to postgresql schema? Is it possible to do with liquibase?
