[postgis-users] ST_Clip on a raster without band crashes the server

[Pierre Racine]

I think when the ST_Clip() crop parameter is set to TRUE, ST_Clip() could just change the extent of the empty raster.... When it is set to false, it just returns the raster unmodified.

I'll fill a bug.

Thanks,

Pierre
