ActiveRecord::ConnectionNotEstablished PostgreSQL + Rails + M1 Error
I recently ran into an error when updating my Macbook pro m1 pro using Macos Ventura.
The horrible error message:
As for today September 2023, I updated my computer with brew update and the other commands. This changed my configuration files on which now, on my usual file system, opt/homebrew/var/postgresql I wasn’t seeing my postgresql@14 directory. Still when running psql -V I was seeing psql (Postgresql) 14.9 (Homebrew).

Ok, so I got the right version, how do I make it work?
Well it turns out that the file path opt/homebrew/var/postgresql is fine, and the version is fine. So in order to make this work I just had to run the following command: pg_ctl -D /opt/homebrew/var/postgres start
And voila! it worked.
I hope this helps you!
