Easily spin up a Postgres database with Postgression

Dev/prod parity is a fundamental concept in continuous development that specifies the tools and technologies used in production should be the same ones used during development. This minimizes hard to diagnose production issues that arise from small technology or version incompatibilities.

While these databases only live for 30 minutes, it's all you need for testing purpose and allows you keep parity between your test and production environments.
