[Qgis-developer] QGIS Loads Black (Blank) Image For PostGIS Out-Db Raster Data

I have an out-db raster on PostGIS which I tried to load in QGIS (v
2.14.12-Essen) utilizing the DB Manager to establish a connection. I could
view the raster table, but when I try to "Add to canvas" it displays a
black (blank) image instead of the raster image.
This raster file exist on the filesystem and when it is loaded directly
into QGIS it displays the image (aerial photo). Also, when the same file is
stored in PostGIS as a raster (IN-DB), it can be viewed in QGIS (using the
DB Manager tool). However, when I reference the same file as an OUT-DB
raster in PostGIS (in this case only the metadata of the raster and the
filepath to the raster file is stored), an attempt to view it in QGIS
(using the DB Manager tool) results in a black image being displayed
instead of the aerial photo.
I would be glad if someone could help me to resolve this.
