If you want to use the quadtree-functionality of GEOS for some goemetry
processing, you don't need PostgreSQL and PostGIS at all.

GEOS is just a geometry processing library, geos by itsself doesn't do
anything with databases.

You can use PostGIS/PostgreSQL for storage of your geometries, or
GDAL/OGR, but you don't have to.
