This project is an overview of how to use pg_dump and cron to
automate backing up a Postgres database and sending it to a remote location.
It is composed of two files - backup-database.js and index.js. All relevant
methods are contained in the former file, which only exposes a single method.
In order to get the project to work, create a .env file and enter the following details
DB_NAME=<your database name>
DB_USER=<your postgres username>
PGPASS=<your postgres password>
