title: Dump and restore in Monetdb
body: <p>I'm new to monet. When it comes to dump/restore activities I would like to use the same functionality of <code>mysqldump</code>. I tried the following:</p>
  
  <pre><code>mclient -u monetdb -lsql --database=my_db --dump &gt; ~/my_db.sql
  </code></pre>
  
  <p>However, when restoring with: </p>
  
  <pre><code>mclient -u monetdb  -lsql --database=my_db ~/my_db.sql
  </code></pre>
  
  <p>I came across the following error:</p>
  
  <pre><code>CREATE SEQUENCE: name 'seq_6620' already in use
  current transaction is aborted (please ROLLBACK)
  </code></pre>
  
  <p>What am I missing? Does this mean I can only feed dumped data to an empty db? Thanks in advance for your hints.</p>
