Provisioning PostgreSQL with Puppet on Vagrant - postgresql

Question

I've got a puppet manifest that resists my attempts to get it working right, given I'm no expert on the puppet DSL, and I'm fairly new to Puppet, I haven't managed to figure this out.
I'm trying to install Postgres using puppetlabs posgres module, creating a default role, and fixing up the DBs to work on UTF8.
Everything runs and installs, but the role doesn't get created. But if I run the provision again, then the role gets created. I assume perhaps has to do with the execution order, but honestly I'm lost.
Here's the code I'm using on my manifest file.
user { "user_vagrant":
ensure => "present",
}->
exec { 'apt_update':
command => 'apt-get update',
path => '/usr/bin/'
}
package { ['vim','postgresql-server-dev-9.1','libmysqlclient-dev','nodejs']:
ensure => 'installed',
before => Class['postgresql::server'],
require => Exec['apt_update'],
}
class { 'postgresql::server':
ip_mask_allow_all_users => '0.0.0.0/0',
listen_addresses => '*',
ipv4acls => ['local all all md5'],
postgres_password => 'postgres',
require => User['user_vagrant'],
}
postgresql::server::role { 'vagrant':
createdb => true,
login => true,
password_hash => postgresql_password("vagrant", "vagrant"),
require => Class['postgresql::server'],
} ->
exec { 'utf8_postgres':
command => 'pg_dropcluster --stop 9.1 main ; pg_createcluster --start --locale en_US.UTF-8 9.1 main',
unless => 'sudo -u postgres psql -t -c "\l" | grep template1 | grep -q UTF',
path => ['/bin', '/sbin', '/usr/bin', '/usr/sbin'],
}

Finally found the right approach to fix both the applied order, and the UTF8 issue which forced me to try the "pg_dropcluster" to begin with. Btw, this is a known issue here's the issue url http://projects.puppetlabs.com/issues/4695
This is the whole file I use to install PostgreSQL 9.1 with UTF8, and RVM ruby. Hope this helps.
