Bob,
PostGIS provides extensions to PostgreSQL's procedural language and
geometric data types so that it can store geo-referenced data, and so
that you can query this data using geo-spatial coordinates.
Software like MapServer (web) and Qgis (desktop) use PostGIS to
provide data in map applications.
The Refractions site already noted is a good start. The MapServer
site is another:
