How to access to postgresql on vagranted virtual machine?

问题

I make via Vagrant virtual machine with postgresql and want to use it as my rails app database.

I use similar Vagrantfile:

Vagrant.configure("2") do |config|
  config.vm.network :private_network, ip: "192.168.33.18"
  config.vm.provision :chef_solo do |chef|
    # I take cookbook from https://github.com/opscode-cookbooks/postgresql
    chef.add_recipe "postgresql::server"
    chef.json = {
      postgresql: {
        config: {
          ssl: false,
          listen_addresses: '*'
        },
        password: {
          postgres: 'postgres'
        }
      }
    }
  end
end

Next I vagrant up and expect that next database.yml will be worked:

development:
  database: app_development
  adapter: postgresql
  host: '192.168.33.18'
  username: root

But this is not happen.. Rake task fails with error:

could not connect to server: Connection refused
    Is the server running on host "192.168.33.18" and accepting
    TCP/IP connections on port 5432?

And I see that port is actually not opened

$ nmap -p 5432 192.168.33.18

Starting Nmap 6.25 ( http://nmap.org ) at 2013-05-07 22:05 FET
Nmap scan report for 192.168.33.18
Host is up (0.00047s latency).
PORT     STATE  SERVICE
5432/tcp closed postgresql

And I can see some postgres processes on vm, and there no any errors in vagrant output, so I believe postgres works normally.

How to setup Vagrant to use db on virtual machine in my rails app?

UPDATE my pg_hba.conf

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer

###########
# Other authentication configurations taken from chef node defaults:
###########

local   all             all                                     trust

host    all             all             0.0.0.0/0               md5

I apologize to all readers, but problem was in my inattention. Though I point listen_addresses: '*' in config, then I reset this config accidentally, so in final config was taken default listen_addresses: 'localhost' value. After fix this port became opened.
