[mapserver-users] Mapserver shows all nodes on a GeometryCollection

[drobins]

Hi Jörg,
I did some research:
the query
select st_astext (ST_CollectionExtract ('POINT (0 0)', 3));
returns "Polygon empty"
select st_astext (ST_CollectionExtract ('POINT (0 0)', 2))
returns "Empty String Line"
select st_astext (ST_CollectionExtract ('POINT (0 0)', 1))
returns "POINT (0,0)

So far so good

However, the query's
select ST_AsText (geom), ST_CollectionExtract (geom, 1)
select ST_AsText (geom), ST_CollectionExtract (geom, 2)
select ST_AsText (geom), ST_CollectionExtract (geom, 3)
returns all the same results
"POINT (137237.8268 431571.3851)"
"LINE STRING (136944.606800001 431208.568799999,136987.418099999
431205.513900001)"
"POLYGON ((138960.872299999 438028.947000001,138954.046100002
438015.9692,138951.5854 438017.2392,138953.609499998
438022.398600001,138962.5392 438042.0042,138973.612100001
438066.173999999,138977.8189 438064.507100001,138970.0799
438048.711399999,138960.872 (...)" 

Any of this rings a bell perhaps?
