Linux: How to install DBD::Pg module?

Just ran into this issue, and on Ubuntu 16.04 Xenial the package you're looking for is:

apt-get install libdbd-pg-perl

You have to install libpq-dev, e.g. on Ubuntu:

sudo apt-get install libpq-dev

On CentOS/RH you can fix it by installing perl-DBD-Pg package with yum

sudo yum install perl-DBD-Pg
