i ll tell you why from my end. I installed Postgres14 via homebrew many years ago on my Apple M1 mac mini. I searched a lot on how to "upgrade" this installation but found nothing. I have a few databases running with data on it which I can't afford to lose if something goes down for more than 1 hour. I wish someone would guide me on how to actually install a newer postgres such as v17 without breaking an existing v14 install or losing data since I am not an expert by any means
