Build on push: 
Manual deploy: 
Scheduled deploy: 
The build is deployed every night at 00:01 UTC (and on manual workflow run). The updated cache of reverse-geocoded addresses is commited back to the repo.
Needs DATABASE_URL environment variable, or in .env.
The following can be used to find out the production database URL (once you've managed
login, or auth:login?)
heroku pg:credentials:url --app fruktkartan-api
(--app fruktkartan-api-dev for the development database)
TODO: even when using the development database, generated links, API calls etc still point at fruktkartan.se, fruktkartan-api.herokuapp.com, etc
