-If you would like to do additional initialization in an image derived from this one, add a `*.sh` script under `/docker-entrypoint-initdb.d` (creating the directory if necessary).

If you need to execute SQL commands as part of your initialization, the use of Postgres'' [single user mode](http://www.postgresql.org/docs/9.3/static/app-postgres.html#AEN90580) is highly recommended.
