Thanks a lot for the tip, it worked as expected.

I don't remember from where I got my version but using a more recent one made it!

Best regards,

I cannot find that specific version in the official git repos, so
maybe this is some hacked versoin of osm2pgsql? The command line
at least looks okay, I tried with pretty much the same command.

I've also checked the pbf and it doesn't contain any duplicates,
so osm2pgsql is wrong here. Maybe it isn't properly deleting the
nodes table before starting the import. Normally it should drop
and recreate table.

In any case, I would recommend to try with a newer version of
osm2pgsql. Either the 0.90.1 release or the newest source from
github.

Kind regards
