The Motion Database is used to keep track of my rolling stock including cars and bicycles. It's a demo database for developing concepts in PostgreSQL and Wavemaker.
I could do photo/image processing in the database if I installed PostPIC. http://drotiro.github.com/postpic/
Create the database and add extensions
createdb -U webadmin motion psql -U webadmin motion
CREATE EXTENSION postgis; # Add support for Large Objects CREATE EXTENSION lo;
# Show installed extensions SELECT * FROM pg_available_extensions WHERE comment LIKE '%string%' OR installed_version IS NOT NULL ORDER BY name;
# Get more info on an extension \dx+ postgis \dx+ lo
