refs #2551 Postgis raster_columns view is returning NULL values for raster overviews with large scale factors. That issue in postgis is described in http://trac.osgeo.org/postgis/ticket/3006 This causes two main problems: - The first overview with scale = NULL is wrongly chosen for rendering always - The messed up scaling factor causes the render symbolizer to spent an insane amount of CPU and memory to render a messed up tiles. The patch in postgis is expected to be released with the new version, a few months from now. |
