[BUG] Migration Error

[mzch]

Describe the bug

When running DJANGO_SETTINGS_MODULE=settings.config python manage.py migrate --noinput, the following error occurred. This seems to happen using PostgreSQL 14 or later. Ref. mailing list article

Running migrations:
  Applying projects.0046_triggers_to_update_tags_colors...Traceback (most recent call last):

The above exception was the direct cause of the following exception:

I solved it using a docker container for the postgres database and changing the database port in the /settings/common.py file as showed below.

I added a docker-compose file in the root folder (above taiga-back) (I don't know if the location matters but worth mention)
The docker-compose.yml :

version: '3.5'

services:
  taiga-db-2:
    container_name: taiga-db-2
    image: postgres:12.3
    restart: always
    environment:
      POSTGRES_DB: taiga
      POSTGRES_USER: taiga
      POSTGRES_PASSWORD: taiga
    ports:
      - "5433:5432"
    volumes:
      - taiga-db-data-2:/var/lib/posrgresql/data
volumes:
  taiga-db-data-2:

Then did docker compose up to run the container

Is worth mention that i ran this code: sudo netstat -nl | grep postgres to check in what port was postgres running, and it showed that it was running in port 5432

I had the database port configured like this, to work with the port that I thought was the appropiate:

DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.postgresql",
        "NAME": "taiga",
        "USER": "taiga",
        "PASSWORD": "taiga",
        "HOST": "127.0.0.1",
        'PORT': '5432'
    }
}

Then I changed the port to 5433 and it works (when the docker container from above is running):

DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.postgresql",
        "NAME": "taiga",
        "USER": "taiga",
        "PASSWORD": "taiga",
        "HOST": "127.0.0.1",
        'PORT': '5433'
    }
}

After this changes the migration ran without error
