Personally, I feel like it's the app that's badly configured if it won't work with Postgres having been installed with either homebrew or the far-better PostgresApp. Backing services should just work with the default install on development. If it needs special configuration, like enabling Hstore on Postgres, it needs to be documented, but honestly I consider it a code smell. That stuff should be auto-configured by the app.
