How to order resources from a specific module? - module

Question

I got some trouble ordering resources from a module.
class { 'postgres' :
charset => 'UTF8',
locale => 'fr_FR',
require => Service['postgresqld'],
}->
class { 'postgresql::server':
}
postgresql::role { 'role1' :
namevar => 'redmine',
password_hash => 'random_md5',
createdb => true,
require => Class['postgres'],
}
postgresql::database_user {'charly':
password => 'random',
role => 'redmine',
require => postgresql::role['role1'],
}
I want to order this, but it appears to have a syntax error on the last line at role.
I'm pretty sure it comes from the capitalized first letter. But Puppet doesn't want to run the manifest if I put a capital letter Postgresql::role['role1] or postgresql::Role['role1]. Without capital letter, I "just" get a warning :
warning: Deprecation notice: Resource references should now be capitalized on line 61 in file /home/charly/testManifests/part1.pp
I'm doing something wrong, but I don't know what. I searched for an answer on the Internet but can't find what I want neither in tutorials nor on the forums.

Try using chaining arrows to your resource group references e.g.
Class['postgres'] -> Class['postgresql::server']
class { 'postgres' :
charset => 'UTF8',
locale => 'fr_FR',
require => Service['postgresqld']
}
class { 'postgresql::server': }
More detail can be found here in the puppet reference Chaining Arrows
