[postgis-users] strange results

[Guido Staub]

Well,
I've downloaded the cvs snapshot and installed this complete version. 
The geometry_columns relation is updated and now have three more 
columns, so I think the histogram2d function is now implemented 
correctly. But the operators don't work. I still have the same outputs 
like I've told before. Does anybody know what I've done wrong? Or do I 
have to use a cvs client to get a more actual version of postgis?

Thanks
Guido Staub
