If you're talking about Open Geospatial Consortium, then what you really
want is PostGIS, the spatial extension to PostgreSQL. PostGIS follows
the OpenGIS Simple Features Specification for SQL and is an excellent
extension with a long history and which is maintained by an overlapping
but independent community.
