Odk setup

Already did setup odk in amazon ec2 linux instance using postgres db
I am struck with following things

1 How do i create a receiving database in PostgreSQL instance to receive
incoming data and store as point features.

2.How to public simple project allowing us to verify that data collected
via ODK android app is making its way via Aggregate into the AWS database
and is readable in QGIS as a point feature dataset and that georeferenced
photos also collected may be displayed in QGIS project.

Please help me on this
