Topology support is added as a separate extension. You must have "base" PostGIS but not topology. Check the docs at postgis.org/docs/postgis_installation.html, but it could be as easy as CREATE EXTENSION postgis_topology;

I keep getting a relation "topology" does not exist error when trying to do topology.toTopoGeom() and my results shapefile has 0 rows. The other topology functions work, though. This is the starting shapefile www2.census.gov/geo/tiger/TIGER2010DP1/Tract_2010Census_DP1.zip
