pg_dropcluser

[mpj17]

I was working through the Linking documentation but I could not start a container with this training/postgres image, as PostgreSQL consistently died with a Exit 126 status reported by docker ps.

The Hub shows that the image has failed to build since 21 July, which allowed me to deduce that it was this commit earlier on the same day that caused the build to fail.

I created my own image (thanks to the great documentation) with the RUN pg_dropcluster line from the Dockerfile from this repository commented out, and I could start a container fine.
