I have been trying out the new ST_Union in 1.4 and have a question.
I note that, whenever I hit an error like this:
NOTICE: TopologyException: found non-noded intersection between 5.74214e+006
7.36573e+006, 5.74304e+006 7.36666e+006 and 5.74339e+006 7.36629e+006,
5.74304e+006 7.36666e+006 5.74304e+006 7.36666e+006
ST_Union fails to produce a result.
Is there anything I can do to address this TopologyException issue within
PostGIS.

Simon
Hi Simon,
I think there are two things to ask here: firstly, when you say that you
were trying out the new ST_Union() in 1.4, does that mean that your
query worked in 1.3? And secondly, which version of GEOS are you using?
( SELECT postgis_full_version(); )
ATB,
Mark.
