Hello, Thanks for your cooperation. Tested on Xenial
1. create xenial instance 2. add proposed repository 3. apt install libpam-runtime 4. apt install postgresql warnings are gone.

NOT AFFECTED TO TRUSTY [Test Case] 1. create ubuntu instance 2. apt install postgresql [Regression Potentials] This change is quite small(just escaping), and it is not code changes but getenv script which made by debian. so risk is minimal in my opinion.
