[postgis-devel] PostGIS RC1/2 and QGIS

[Carl Anderson]

the offending statement that QGIS is making is

declare qgisf binary cursor for select oid,asbinary(shape,'NDR') as 
qgs_feature_geometry from case6 where shape && GeometryFromText('BOX3D(  
2288006.545455   1472366.000000,  2291123.454545   
1475094.000000)'::box3d,102667)
