Обсуждение: [GENERAL] GDAL OUT-DB RASTER SUPPORT
Hi All,
I am getting a black image when I try to display PostGIS out-db rasters. I discovered that it has to do with GDAL support for out-db rasters as stated in the link below for a similar issue (over 1 year back):
https://hub.qgis.org/issues/12133
The last comment by Jürgen Fischer states "... only black images. So it's a dependency issue (GDAL complains ERROR 1: This raster has outdb storage. This feature isn't still available)."
I have also been told in the link below that "out-db support is not implemented yet in the GDAL PostGISRaster driver.":
https://lists.osgeo.org/pipermail/gdal-dev/2017-April/046512.html
I would like to know how to solve this issue of displaying postgis out-db rasters in QGIS?

There is an issue for it: https://trac.osgeo.org/gdal/ticket/3234 According to it out-db support was implemented in PostGIS 2.0. So I would say you need to ask the PostGIS list what the situation really is. This list(--general) is not going not be of much help as what is you are asking about is outside the code the core Postgres community maintains. -- Adrian Klaver adrian.klaver@aklaver.com
