Where can I get osm2pgsql on my computer?
Get osm2pgsql. To download the windows version of osm2pgsql, navigate your web browser to http://wiki.openstreetmap.org/wiki/Osm2pgsql#Windows. Unzip the file on your system. You should move the unzipped folder to a location where you will not move it later, because we need to add its location to the system path.
Why is my OSM not finding the application?
If you don’t see an error message like this, and it says that it cannot find the application osm2pgsql, then you may have entered the Path variable incorrectly. Before we can run osm2pgsql we need to have some raw OSM data to import into a database.
How to create a roads table in osm2pgsql?
Notice that osm2pgsql creates a separate table for different object types – points, lines, and polygons. It also creates a roads table, which contains only major roads. Select one or more of the layers and click “Add.” If asked, choose WGS84 as the CRS. If everything is successful, you will see the layers you selected displayed in QGIS.
Which is the best tool to import OpenStreetMap data?

What do I need to load openstreetmap.osm XML file?

There are compiled binaries available for many Linux variants, Windows, and Mac OSX. If you are on windows, go here http://wiki.openstreetmap.org/wiki/Osm2pgsql#Windows_XP.
Do you need PostGIS extension for osm2pgsql?

How are relations parsed in osm2pgsql and Mapnik?
The relations are parsed. Osm2pgsql has special handling for a limited number of types: multipolygon, route and boundary. The code will build the appropriate geometries by referencing the members and outputting these into the database. Indexes are added to speed up the queries by Mapnik.
