Motion database

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
