Is the version of pg_dump 9.3 here? When upgrading to a new release you
should use the newer (in this case 9.4) version of pg_dump to perform the
migration dump.
What are the exact releases of 9.3 and 9.4 upon which you are operating?
Does the dump restore into 9.3 correctly?

A quick visual doesn't spring anything obvious. I haven't attempted to
reproduce via the supplied scripts.
