PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially
enables"the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems
(GIS),much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS "Simple Features Specification
forSQL" and has been certified as compliant with the "Types and Functions" profile.

There were sessions on this at the west coast Postgres conference in San Francisco. I don't know if the sessions tapes
areavailable on the web or not.
