[postgis-users] import export file kml

[french30 at inwind.it]

Hi,
use PostGIS 1.5.0,
I would like to import KML files into batabase and export data in the database 
into a KML file.
use to export fwtools 2.4.7 and operation works, to import KML files with 
fwtool
write:
ogr2ogr-f "PostgreSQL" PG: dbname = PostGIS user = postgres password = 
postgres host = localhost port = 5432 "roads.kml
But it gives me an error: unable to find drivers 'Postgres'.
how can I fix this?
Can I import and export KML files directly without using fwtools but use 
PostGIS?
Thanks for your help.
