When I use osm2pgsql to import the planet data into postgresql ,and the "nodes" "ways" "rels"have been read in ,when the shell shows "Committing transaction for planet_osm_point WARING there is on transaction in progress" then the progres shut down! what's wrong with it ? Can anyone tell me ? With mant thanks
