[postgis-users] Topology Postgis 2.0

[ps.tiara]

I used PostgreSQL 9.1 and PostGIS 2.0 for PostgreSQL 9.1

I tried in two ways..
FIRST, I populated geometry to the schema using CreateTopoGeo, and then
updated 
the topology column using CreateTopoGeom... (the query and data attached)
but when i visualized the result of topology in x3d, it was mess..maybe i
made a mistake by wrong query??

SECOND, i tried to update the topology column using toTopoGeom..but
this not succeeded..the query and the message error as below

UPDATE simpanglima.ruang
SET ruang_topo = topology.toTopoGeom(ruang_geom,'simpanglima_topo',3)
WHERE rid='1';


ERROR:  function topogeo_addpolygon(unknown, geometry, numeric) does not

LINE 1: ...yer_id, element_type, element_id) SELECT 5, 3, 3, topogeo_ad...

3.32183207231238e-008);
CONTEXT:  PL/pgSQL function "totopogeom" line 129 at EXECUTE statement



Which one is the best methode to complete my research?
Many thanks..
