Well... in "slim" mode, osm2pgsql already tracks all nodes and the
relationships between nodes, ways, and relations; it just does so in a
different way (using array columns instead of link tables). That part of
the "osm2pgsql schema" is not fundamentally different from the
"pgsnapshot schema"; in fact I believe it would not be too hard to make
osm2pgsql use the pgsnapshot schema for slim mode instead of its own
array tables. This would probably come at a slight speed penalty but
could be interesting for users like Stefan if they want a multi-purpose
But yes - it is not a matter of "configuring" osm2pgsql, it would need
some decent coding.
