title: postgres copy tables from another database using pg_dump?
body: <p>I would like to copy two tables from database A to database B, in postgres
  how can I do it using pg_dump without losing the previous tables and data in database B ?</p>
  
  <p>I read some answers in Stack Overflow suggesting using pg_dump but in the documentation page I read?</p>
  
  <blockquote>
    <p>The idea behind this dump method is to generate a text file with SQL
    commands that, when fed back to the server, will recreate the database
    in the same state as it was at the time of the dump</p>
  </blockquote>
  
  <p>Doesn't that mean it will delete the previous data in database B?</p>
  
  <p>If someone could tell me step by step solution to move two tables in database A to database B without losing any previous data in Database B, it would be helpful.</p>
