PostGIS for the Geographer
Series of simple example PostgreSQL/PostGIS scripts that geographers (or anyone) might find useful.
New scripts will be added over the next couple weeks, that use sample data that is available below.
All scripts and tables used here are based on the GEOMETRY data type
If there are any specific PostgreSQL/PostGIS scripts you would like to see, shoot me a message @GISDoctor.
Boundless also has a really good intro to PostGIS workshop - check it out here.
