ah..now..I am pretty sure that osm2pgsql only processes a limited set of
relation types.  From the

6) The relations are parsed. Osm2pgsql has special handling for a

 limited number of types: multipolygon, route, boundary

 The code will build the appropriate geometries by referencing the

 members and outputing these into the database.

On my database I can do :

select name,route from planet_osm_line where osm_id<0;

and get a log list of relations with things like this in my default.style

node,way   religion     text         nocache

node,way   route        text         linear

node,way   service      text         linear

I do not think I told it to do anything special to include route relations.

Are you trying to use a different sort of relation?
