[postgis-users] Problem with ST_Union()

[Fred Lehodey]

Hi,

A table (attached) with all records having st_IsValid() true, using
ST_Union() returns:
-  [TopologyException: found non-noded intersection between  57903.1
-273111, ...etc]
with postgis 1.3.5 GEOS 3.0.3
- [GEOSUnionCascaded: TopologyException: side location conflict at 565.521
157.774]
with postgis 2.0.0SVN GEOS 3.3.0

Any idea ?

Regards,
Fred
