I believe not. Referred issue looks like a passwd or SSL problem. The PostgreSQL is running locally on a default port 5432 (therefore no port specification is needed).
My situation is such that I am using PostgreSQL as a separate cloud service (on Digital Ocean) and running on a non-standard port. Therefore I need to specify the port explicitely. I specified it in the connection string so far but as it will be constructed from env variables I need to know the mechanism how to pass it through.
I tried to keep the downtime as low as possible and therefore prepare maximum beforehand while the current version is still running. I could pull the new version and do some reverse-engineering of the initalization code but I supposed it should be a simple qustion-answer.
So, is there any specific setting (env variable or e.g. hostname:port format of the ENV_HOST variable) that is ready to use or shall I do an exploration by combat?
