Seems to me that it is about GDAL having support in their PostGISRaster
driver for file located raster images.

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.
