Providing PosgreSQL with a stroller doll

Question

I have a puppet manifesto that resists my attempts to make it work correctly, given that I am not an expert in puppet DSL, and I'm pretty new to Puppet, I could not figure it out.

I am trying to install Postgres using the puppetlabs posgres module, creating a default role and fixing databases for working with UTF8.

Everything is executed and installed, but the role is not created. But if I run the condition again, the role will be created. I suppose it may be related to execution, but honestly, I got lost.

Here is the code I use in the 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'],
}
