 Priority:  medium       |   Milestone:  PostGIS 2.1.0
Component:  raster       |     Version:  trunk

-------------------------+--------------------------------------------------
 When the GDAL Warp API is called with a raster that has no SRS, the API
 will error regardless of operation.  But if a "garbage" SRS (completely
 valid SRS but not correct for the raster) is used, no error happens.

 Testing was done on the gdalwarp utility using a raster with its correct
 SRS in addition to other "garbage" SRSes on resampling operations (no
 reprojection).  Test results indicate that the output rasters are
 identical.

 This usage of "garbage" SRS would only take place when RASTER_GDALWarp()
 is called with no output SRID, thereby nullifying any possibility of
 reprojection.
