title: how to generate database table INHERITANCE postgresql script with Powerdesigner
body: <p>I have two tables, "child" and "parent", "child" must inherit all columns of "parent", I use 'Generalization' link between the two tables in the conceptual model (class diagram), when I generate physical model it give me this result : </p>
  
  <pre><code>create table child (
     id                   INT4                 null,
  ); 
  
  create table parent (
     id                   INT4                 null,
     name                 INT4                 null
  );
  
  alter table child
     add constraint FK_CHILD_GENERALIZ_PARENT foreign key (id)
        references parent(id)
        on delete restrict on update restrict;
  </code></pre>
  
  <p>But in Postgresql inheritance is not a FK constraint, it must give me : </p>
  
  <pre><code>create table child (
  
  ); INHERITS (parent);
  </code></pre>
  
  <p>What I miss ??</p>
