What actually happened
jmt@nala:~$ docker run --rm -t -i --link `cat /var/run/database_prod.cid`:db mathuin/database bash

What I expected to happen
I expected that container IDs would work when used with the --link option to the run command.
Why I expected that to happen
http://docs.docker.io/en/latest/use/working_with_links_names/ describes how to work with links between containers. The --link option takes one argument -- a name and an alias separated by a colon. In the general case, Docker supports the use of container IDs wherever names are supported. Examples include commands such as top.
My current workaround
jmt@nala:~$ docker run -ti --rm --link `cat /var/run/database_prod.cid | xargs docker inspect --format='{{.Name}}'`:db busybox sh
/ # echo $DB_PORT_5432_TCP_ADDR
