PostGIS and 7.4.1

Hello all,

I would like to know if the spatial support available in the
7.4.x versions of PostgreSQL is the same thing as PostGIS. If
not, what are the differences?

7.4.X spatial support is limited to points, lines, etc. PostGIS is an
extension that implements the full GIS specification.

Is it possible to retrieve spatial data through ODBC or libpq?

Sure. They are no different from ordinary types, except they are loaded
in independently.
