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 Andreas
