Migrate DB to use Postgres

[morisy]

So that the database remains stable, we need to swap from SQLLite to PostGres. This is a relatively high priority item so that we can ensure data is dropped properly in.

We’ll also need to make sure this works well with the deployment process after we move the code over.

@morisy Need any help or any remaining tasks that I could help with? 😄

@JakeTobin I would check in with @kbalajisrinivas or @gsireesh next time they're in! This is above my knowledge grade.

Hi! Sorry, I've been out. @JakeTobin the code was already set up when I started working on this, but definitely needs a little bit more documentation. There are environment variables defined implicitly in the settings file that, when set, will cause the server to connect to a PG instance rather than a SQLite store.
