Question:
Docker compose fiware WireCloud data persistance not loaded from volume

Description:
I am using a docker container for my FiWare WireCloud. It is working properly but when I stop my container with docker compose down and restart it with docker compose up all my data are erased even if I specified a volume for the postgresql database and I have the following error:

ERROR: relation "wirecloud_workspace" does not exist at character 370

If I want to make it work again, I have to recreate the whole database from scratch (initdb & createsuperuser)

What I would like to do is to be able to save my wirecloud data inside a volume and be able te backup it and reload it. Here is my current docker-compose.yml file in version 3:

version: '3.3'
services:

iot-mongo:
image: mongo:3.2
ports:

• "27017:27017"
  volumes:
• ./data/mongo:/data/db

orion:
image: fiware/orion:1.9.0
links:

• iot-mongo
  ports:
• "1026:1026"
  command: -dbhost iot-mongo

nginx:
restart: always
image: nginx:1.13
ports:

• "80:80"
• "443:443"
  volumes:
• ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro
• ./nginx/sites-available:/etc/nginx/sites-available
• ./letsencrypt/well-known:/www/letsencrypt
• /etc/letsencrypt/:/etc/letsencrypt/
• wirecloudwww:/var/www/static
• wirecloudinstance:/opt/wirecloud_instance
  links:
• wirecloud:wirecloud
• orion:orion
  postgres:
  restart: always
  image: postgres:latest
  ports:
• "5432:5432"
  volumes:
• postgresdata:/var/lib/postgresql
  environment:
  POSTGRES_USER: postgres
  POSTGRES_PASSWORD:
  POSTGRES_DB: postgres
  PGDATA: /tmp
  wirecloud:
  restart: always
  image: fiware/wirecloud:1.0-composable
  links:
• postgres:postgres
  volumes:
• wirecloudwww:/var/www/static
• wirecloudinstance:/opt/wirecloud_instance
  volumes:
  wirecloudwww: {}
  wirecloudinstance: {}
  postgresdata: {}

I also tried with docker-compose v1 like they show in the documentation but the result is the same.
