PostgreSQL is being installed with SQL_ASCII using Puppet - postgresql

Question

I'm trying to build Vagrant box provisioned with Puppet.
I use Ubuntu 12.04 LTS box from http://files.vagrantup.com/precise64.box.
I also use http://forge.puppetlabs.com/puppetlabs/postgresql module to install PostgreSQL with the following manifest:
class db {
class { 'postgresql': version => '9.1' }
class { 'postgresql::server': }
}
class { 'db': }
It installs correctly, but databases are created with SQL_ASCII encoding:
$ psql -l -U postgres
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+-----------+---------+-------+-----------------------
postgres | postgres | SQL_ASCII | C | C |
template0 | postgres | SQL_ASCII | C | C | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | SQL_ASCII | C | C | =c/postgres +
| | | | | postgres=CTc/postgres
After googling I've thought it might be a locale problem, but it looks correct to me:
$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE=
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
Do you know what should I do to be able to install PostgreSQL with UTF8 encoding default? It'd be also nice to be able to use Puppet for this.

Answer 1

Apparently, it is Puppet bug http://projects.puppetlabs.com/issues/4695. Added the following code from issue comments as a workaround:
# workaround for http://projects.puppetlabs.com/issues/4695
# when PostgreSQL is installed with SQL_ASCII encoding instead of UTF8
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',
require => Class['postgresql::server'],
path => ['/bin', '/sbin', '/usr/bin', '/usr/sbin'],
}
