But i stuck at 3rd step....
Now open a new command window and try the psql command
These instructions assume that you already have a PostgreSQL 'postgres'
user
Open a command prompt and enter the following commands ( the password will
always be: postgres )
         createdb -E utf8 -U postgres osm

         psql -U postgres -d osm -f "C:\Program
Files\PostgreSQL\9.1\share\contrib\postgis-2.0\postgis.sql"

         psql -U postgres -d osm -f "C:\Program
Files\PostgreSQL\9.1\share\contrib\postgis-2.0\spatial_ref_sys.sql"

         psql -U postgres -d osm -f "C:\Program
Files\PostgreSQL\9.1\share\contrib\postgis-2.0\legacy.sql"
