Postgres problems since homebrew install

A few days ago I followed a git beginners book (Jumpstart Git) and installed homebrew. Everything went fine. But since then I have problems to launch an app which works with PostgreSQL. It cannot start the database, access to 127.0.0.1 on port 9977 is denied.
How could I fix that? The app is essential to me for it’s my job administration software (called »revolver«) :frowning:

Here is what I found in log file today.

Can someone help please? That would be great!

Revolver is not Homebrew-supplied software, so I suggest you ask for help via Revolver’s support channel.

I would not have asked here without asking at revolversoft first.

So If your idea is to be helpful and you have insight into details of homebrew please consider to think about what homebrew changes on first install concerning postgres and/or localhost port 9977.

Thanks for any constructive hint,

Carsten

Homebrew doesn’t have any parts that affect the ports your existing software runs on. If you just installed git through homebrew there’s no way that this is a problem with homebrew.

Thanks, Sean, for your answer.
I’m just trying to figure out what happened to my Mac step by step.
Hope I will find the way back …

Thanks again,
Carsten
