Issues with Docker container on port 5432

[ozzytekconsult]

Hi,

I'm having an issue running PostgresML in a Docker container, on an Ubuntu 22.04 server.
Like this

docker run -d --name postgresml --restart always  \
    -v postgresml_data:/var/lib/postgresql \
    -p 5433:5432 \
    -p 8089:8000 \
    ghcr.io/postgresml/postgresml:2.8.2 

The Ubuntu 22.04 server is running Postgres 16 locally on port 5432 (not on a Docker container).
Hence my exposing the containerized Postgresml on port 5433.
So I don't see any reasons why I should be getting the errors below when I try to run the container

Any idea why this is happening and how to fix it?

Thanks
