Import ways without tag using osm2pgsql

Hey OSM community,
I have a very special problem when importing OSM Data with osm2pgsql. I was searching for days on how to import ways which do not have any tag but which are part of a relation (which itself has tags) into PostgresDB. Take the following way for example:

As you can see it does not have any tags but is part of the relation which is tagged as a cross country slope. When I import data into postgresql, the way 50126690 is not imported. Even when I use --hstore option which should keep all objects if you believe documentation on the way will not be imported into planet_osm_line table. My looks like that:

# Deleted tags
# These are tags that are generally regarded as useless for most rendering.
# Most of them are from imports or intended as internal information for mappers
# Some of them are automatically deleted by editors.
# If you want some of them, perhaps for a debugging layer, just delete the lines.

# These tags are used by mappers to keep track of data.
# They aren't very useful for rendering.

Can anybody point me into the right direction on how to import those ways???
Thanks for helping

No tips? This cannot be that hard… Isn’t there a wildcard for any tag or no tags?

The forum isn’t much used for development chat - other places to try would include the dev mailing list , the help site or #osm-dev on IRC (on I can’t guarantee that you’ll get an answer there, but it’s more likely than here.
