osm2pgsql throws away all objects that don't have the right tags if you
don't use the hstore features and it don't store way-node and
relation-member information if you don't use slim-mode.
In general osm2pgsql is targeted at generating a smaller database that
fits exactly on rendering a style - not for serving an xapi-like query
service - although the one or the other might be tricked into working
with the other, they're not made for each other.
