An in-range update of pg is breaking the build 🚨

## The dependency [pg](https://github.com/brianc/node-postgres) was updated from `7.12.0` to `7.12.1`.

🚨 [View failing branch](https://github.com/coding-blocks/judge-api/compare/master...coding-blocks:greenkeeper%2Fpg-7.12.1).

This version is **covered** by your **current version range** and after updating it in your project **the build failed**.

pg is a direct dependency of this project, and **it is very likely causing it to break**. If other packages depend on yours, this update is probably also breaking those in turn.
