Unable to start docker compose project - error thrown

Hi, I've tried searching but the issues I found were supposed resolved in an older version or very old.

I've modified the docker compose file to use relative paths inside the compose folder instead of /opt, added labels for traefik, and changed the version of core and web to 0.5.2, still pulling images from docker hub. I'm unable to start the containers. core throws the following error repeatedly:

TIA. It's truncated, so let me know if you need to see more. Thanks.

Start by reviewing the modified Docker Compose file and reproducing the failure with the 0.5.2 core and web images. Follow the traceback from Mailman's initialization into SQLAlchemy's database setup and verify that the containers start without the reported postgres dialect error.
