I would disagree:
postgres@killi:~> /usr/local/pgsql94/bin/postgres --single -D
/usr/local/pgsql94/data/ <<-EOSQL
CREATE DATABASE test_db;
EOSQL
PostgreSQL stand-alone backend 9.4rc1
backend> LOG: statement: CREATE DATABASE test_db;
backend> postgres@killi:~>
I see nowhere in your init-master.sh where Postgres is restarted.
Check ps ax | grep postgres on your primary to see what is actually
running. Could be that the single user mode is shut down and a regular
instance is started up, but with different settings then you think. We
still have not explored where the Postgres in your containers are coming
from and how they are set up in image: mdillon/postgis:9.3.
