Notes!

Once PostgreSQL is installed on a machine...

# Create a user that can start interacting with the DB other than postgres
{~} % sudo su postgres -c 'createuser -P --superuser bassman'
# With that user, create a DB
{~} % createdb --username=bassman --password loc

# Remove PostgreSQL from Mac
$ open /Library/PostgreSQL/<ver>/uninstall-postgresql.app
$ sudo rm /etc/postgres-reg.ini
$ sudo rm -rf /Library/PostgreSQL
