title: pgAgent installation in PostgreSQL
body: <p>I have installed PostgreSQL 9.1 on ubuntu 12.04 64-bit. I try to run Aplication Stack Builder and install pgAgent. </p>
  
  <p>At first I am asked for root password, which I provide, after I choose PostgreSQL 9.1 on port 5433 as the only option. On next screen I tick pgAgent and click Next a few times to get to the Setup screen with verification the postgradeSQL installation details. The Host is local, the User Name is postgres and I type my password for postgrade which I use when open pgAdmin III. When I click next I have a warning:</p>
  
  <p><code>psql.bin: could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connection on port 5432?</code></p>
  
  <p>When I try pgAdmin it does work with password I provide but it looks for me like this password is not accepted by Stack Builder. I also provide my admin password on the begining so it should be able to do everything with <code>sudo</code> privilage. I don't know what to do now and what is the problem. Should I run something else before Stack Builder? </p>
