Description of problem: When a slave is restarted with same volumes, PostgreSQL server won't start. This was solved in the following PR: https://github.com/openshift/postgresql/pull/82 so all we need is to respin the images with the PR solved.
Just a note, I have created an issue on github for the PostgreSQL image to introduce a better method for solving this problem other than the PR mentioned in the Description. Solving that issue before and introducing that fix into the updated image would be helpful: https://github.com/openshift/postgresql/issues/84
