Fuel Devops Postgres Configuration is not clear

[Michael Petersen]

There are issues with configuring the environment due to the assumption that users know Postgres. We need to clarify if you are supposed to use a password or not. If not then we need to specify the expected configuration/results.

https://docs.fuel-infra.org/fuel-dev/devops.html

Section 3.3.3

Set local peers to be trusted by default, create user and db and load fixtures.

sudo sed -ir 's/peer/trust/' /etc/postgresql/9.*/main/pg_hba.conf
sudo service postgresql restart
sudo -u postgres createuser -P <user> # see default <user> and <db> below
sudo -u postgres createdb <db> -O <user>
django-admin.py syncdb --settings=devops.settings
django-admin.py migrate devops --settings=devops.settings
in 2.5.x version, default <user> and <db> are devops
in 2.9.x version, default <user> and <db> are fuel_devops

This should let us know if we are expected to setup a Postgres without a password. The issue is that when we connect to localhost a password is expected.
