Postgres shuts down immediately when started with docker-compose. The yaml file used is below
version: '2'
services:
postgres:
image: postgres:9.5
container_name: local-postgres9.5
ports:
- "5432:5432"
The log when docker-compose up command is executed

Postgres seems to work fine when a container is started using the same image with docker run
docker run --name local-postgres9.5 -p 5432:5432 postgres:9.5
I tried your docker-compose and the service seems running in the container:
root@0afe99de0f0b:/# ps aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
postgres 1 0.5 0.8 227148 16128 ? Ss 14:42 0:00 postgres

Anyway, for my project I use another image for postgresql: https://github.com/sameersbn/docker-postgresql. This one works fine.
If you look at your log output, the following lines appear towards the end:
local-postgres9.5 | server stopped
local-postgres9.5 |
local-postgres9.5 | PostgreSQL init process complete; ready for start up.
Apparently, stopping and restarting the Postgres server is part of the initialisation process. In fact, the second-to-last line says
local-postgres9.5 | LOG: database system is ready to accept connections.
