[postgis-users] ERROR: Error performing intersection.

[Andreas Forø Tollefsen]

What could be the reason for this query:

SELECT p.gid, array_to_string(array_agg(distinct(CASE when (g.cowgroupid <>
0) then g.cowgroupid end)), ';'), CAST(SUM(ST_Area(ST_Intersection(p.cell,
g.geom))) AS decimal (6,4)), g.type, g.startyear, g.endyear
FROM priogrid p, "geoepr-20100212-1248" g WHERE ST_Intersects(p.cell,
g.geom) GROUP BY p.gid, g.cowgroupid, g.type, g.startyear, g.endyear;

to produce the following error?

ERROR:  Error performing intersection.

********** Error **********

ERROR: Error performing intersection.
SQL state: XX000
