Hello List,

Postgis and mapserver are working OK in my application except
when I use itemnquery instead of itemquery. When I use
Itemnquery using a jbox rectangle postgis complains:

msPOSTGISLayerGetShape(): Query error. Error executing POSTGIS SQL statement (in FETCH ALL): DECLARE mycursor BINARY CURSOR FOR SELECT asbinary(force_collection(force_2d(the_geom)),'NDR') from test_vlakken WHERE OID = 106744 -ERROR: cursor "mycursor" already exists 
etc.....

I saw two other recent questions regarding this problem but there was no answer to them.
Is this a bug?

I am using mapserver 4.0 with postgis 0.8 on postgresql 7.4.1 on redhat linux 9.

Regards,

W. Blanken
