Hello,
I'm investigating how to use a Heroku follower database (https://devcenter.heroku.com/articles/heroku-postgresql#follow-beta) as a read slave using Octopus. Is there any way of doing this outside of hard-coding the HEROKU_POSTGRES_URL values from heroku config into shards.yml? It'd be nice if there was a way to just reference it through ENV, although I guess that means I need to parse the URI myself.
