Fix problem with Puppet cron job

Fix problem with the puppet master getting lots of emails
because the cron job keeps erroring out with the message :

Warning: Module 'puppetlabs-stdlib' (v3.2.0) fails to meet
some dependencies:
'puppetlabs-concat' (v1.1.0) requires 'puppetlabs-stdlib' (>= 4.0.0)

We were trying to install puppet module "puppetlabs-postgresql"
version 3.0.0 which requires module "puppetlabs-stdlib" > 3.0.0.
Since our project does not need "puppetlabs-postgresql" yet the module
has been commented out. If the project ever starts using the module
"puppetdb" we will need to re-enable the module "puppetlabs-postgresql"
