I followed a tutorial to install a PostgreSQL server on my Mac OS X Mavericks, and to import some OSM data with the osm2pgsql converter (https://www.mapbox.com/tilemill/docs/guides/osm-bright-mac-quickstart/).
I used OSM data in the
.osm.pbf format for the import. That works fine.
Is it possible to use the formats
.osm.bz2 as well? And maybe other formats?
Do I then need to add certain options to the osm2pgsql command, depending on the chosen format?
I intend to import only small amounts of data into the database, mainly for visualizing purposes in TileMill.
