title: How to set tab delimiter using psql -F
body: <p>I want to dump a select query to a tab-delimited text file using psql -F. However, this doesn't work:</p>
  
  <pre><code>psql -Umyuser mydb -F '\t' --no-align -c "select * from mytable" -o /tmp/dumpfile.txt
  </code></pre>
  
  <p>That makes the delimiter a literal \t. How do I get it to use real tabs instead?</p>
