Docker with data inside

Hello,

I am trying to create a docker Postgres container with database inside.

When I try to run the container I have the following error

2016-10-20 08:58:33 UTC FATAL: the database system is starting up
2016-10-20 08:58:33 UTC DEBUG: shmem_exit(1): 0 before_shmem_exit
callbacks to make

2016-10-20 08:58:33 UTC DEBUG: proc_exit(1): 1 callbacks to make
2016-10-20 08:58:33 UTC DEBUG: exit(1)

The entry point is

su -c "/usr/lib/postgresql/9.4/bin/postgres -d 3 -D
/var/lib/postgresql/9.4/main -c
config_file=/etc/postgresql/9.4/main/postgresql.conf" postgres

and the output of command
