importing osm file into a postgres/postgis database
You need to install the postgis extensions into your postgres database. Assuming that you have postgis installed on your machine you need to do something like:
psql <database> < /usr/share/postgresql/8.4/contrib/postgis-1.5/postgis.sqlThe exact path to postgis.sql will depend on the distribution you are using and how it has packaged postgis. You may also want/need to install the spatial reference systems table with a command like this:
psql <database> < /usr/share/postgresql/8.4/contrib/postgis-1.5/spatial_ref_sys.sql
This is an example command:
osm2pgsql -c -d your_country -U postgres -W -H localhost -P 5432 -s -k -x -p osm -S default.style ..\your_country.osm.bz2
