airflow runs connections check against metadata db before init db - postgresql

Question

I am running airflow locally based on dockerfile, .env, docker-compose.yaml and entrypoint.sh
as "docker-compose -f docker-compose.yaml up"
And just after "airflow init db" in entrypoint.sh I am getting the following error:
[after it all is cool, I can run airflow. But this drives me crazy. Can anyone help me to resolve it, please?]
what's strange is that service queries the tables even before the db has been initiated
