[Impact]

When installing postgresql, many warning msgs are raised
Please refer to Original Description

## Corrections
In trusty, escaping is missing but not the same symptome. 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.

[Original Description]

When installing postgresql on Ubuntu 16.04 (xenial), the following
warning are raised:

This is due to the fact that unescaped brace are deprecated in Perl
5.22.
