[postgis-users] Where does Postgres end and PostGIS begin?

PostgreSQL has some built in geometry types but it doesn't know
anything about spatial reference systems or have a myriad of useful
spatial data management and analysis functions.

I've noticed that macports does have a postgis package.  Do I actually need it?  I guess I'm just really fuzzy as to exactly what PostGIS is relative to Postgres.
