First off thanks Gents.

1) I installed Postgres using Homebrew and the version is - postgres
(PostgreSQL) 9.4.4
Not sure what else gets installed with Postgres when installed with Brew

2) After installing postgres, i just followed the instructions prompted by
brew/postgres in the terminal - I can't remember what they were, but I
believe it was 3 steps (one was for Postgres auto start)

3) Not sure... I tried creating a user and password and that's when things
started. I looked online on how to create a user and followed some
suggestions, but to no avail, so I thought my installation was buggy, so I
tried to start from scratch and that's at that point that I delete the
folder "postgres" inside usr/local/var/

4) I uninstalled using brew and then deleted the above mentioned folder. 

I'm not trying to contradict what you guys are saying (you guys obviously
know better than me), but in my mind it doesn't make sense why it can't be
started from scratch if I did not have any users or databases. Again, I'm
just trying to understand why this file is so needed/critical.

Thanks again guys.

Sergio
