Stop vagrant-vbguest automatic updates

From your host machine, if you have the vagrant-vbguest plugin installed, make sure you deactivate it for this specific VM. To do that, set auto_update to false in your Vagrantfile:

    PSQL

Magic words:
psql -U postgres
Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

# This script will open all files from a git diff or a git show in vim.

# My bash skills are a bit primitive so this can probably be done more intelligently

# Usage:
#   gitopen -- opens all added files that have changed since HEAD
#   gitopen diff HEAD -- these are the default parameters
#   gitopen diff master -- opens files that have changed from master
