In general, you should be running PostgreSQL 9.5.

The commands that pups ran are only present in the postgres.9.3.template.yml file; presumably, somewhere in your container definition you’ve got something that looks like:

templates:
  - "templates/postgres.9.3.template.yml"

If you remove the .9.3 from there, you’ll have a much more up-to-date time.
