title: Can't connect to pgpool
body: <p>I'm playing around <a href="http://www.pgpool.net/mediawiki/index.php/Main_Page" rel="nofollow">pgpool2</a>. </p>
  
  <p>I'm connecting to postgresql which is running on port 5432 with command <code>psql -U postgres -p 5432</code> and it's connecting normally. </p>
  
  <p>When I'm connecting to pgpool2 running on 9999 port with command <code>psql -U postgres -p 9999</code> - it returns back dialog like: 
  <code>psql: root@master:/linux/path#</code></p>
  
  <p>What I'm doing wrong? Is there way to connect to pgpool using psql? 
  I cannot connect to it from application also. </p>
  
  <p><strong>UPD</strong> I've got following error <code>pool_do_auth: maybe protocol version mismatch (current version 3)</code></p>
  
  <p><strong>Solved</strong> : Problem was in pgpool auth on backends. Editing <code>pg_hba.conf</code> fixed problem. </p>
