Ruby Python and Postgre install

install_postgre.sh

From http://stackoverflow.com/questions/1383126/django-python-beginner-error-when-executing-python-manage-py-syncdb-psycopg2
Just had to unlink postgreSQL

`brew unlink postgresql`
then

`xcode-select --install`
and finally

`brew install postgresql`

`brew install openssl`
But then rails server didn't work so:

`rvm get stable`
To see which was my current_ruby

`rvm list`

`sudo rvm uninstall <current_ruby>`

`rvm install <current_ruby>`
Now create initialize a postgredb

`initdb /usr/local/var/postgres9.4.1`
And start your server

`pg_ctl -D /usr/local/var/postgres9.4.1 -l logfile start`
You're done.


To have launchd start postgresql at login:
    ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then to load postgresql now:
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Or, if you don't want/need launchctl, you can just run:
    postgres -D /usr/local/var/postgres
