Do you mean that external raster == stored out of DB?
Could you please check the backtrace - the crash may be inside GDAL, I think it does not support out of DB rasters yet.
#2
Updated by Paolo Cavallini about 9 years ago
Yes, I mean imported through the -R option.
Are you sure GDAL does not support them?

I'm not 100% sure but judging it's not supported from:
- GDAL ticket: http://trac.osgeo.org/gdal/ticket/3234
- GDAL source: http://trac.osgeo.org/gdal/browser/trunk/gdal/frmts/postgisraster/postgisrastertilerasterband.cpp#L144

I confirm out-db PostGIS raster are not supported yet in GDAL. After the fix in GDAL trunk (http://trac.osgeo.org/gdal/changeset/28530 that was a fix for a regression in trunk only and should put GDAL in the state of GDAL 1.11), I cannot get crashes however, just blank images with error messages in the console. Paolo mentionned to me he uses GDAL 1.10.1 : there have been significant rework in GDAL 1.11 in the PostGIS raster driver that might explain GDAL 1.11 and later being at least more robust when ingesting out-db raster.

- Resolution set to up/downstream
- Status changed from Open to Closed
I can't produce a crash either - only black images. So it's a dependency issue (GDAL complains ERROR 1: This raster has outdb storage. This feature isn't still available).
