Comment(by dustymugs):

 Replying to [comment:3 pracine]:
 > We are then near to full support for out-db raster right?
 >

 Yes.  Out-db rasters are supported for analysis.  Out-db rasters have no
 write support so you cannot use ST_SetValue or anything like that.

 > I guess one thing missing is raster2pgsql to create filesystem tiles
 (and overviews) in a new folder when using the -t option in conjonction
 with the -R option. That would require to specify a new path where to
 store the tiles though. We could also just prohibit using both options at
 the same time and take for granted that users are registering already made
 tiles (using GDAL for example)...

 It would be nice to have out-of-db overviews supported.  Some work will
 need to be done to see how best to hook the overview into PostGIS Raster.

 > We also need a way to convert out-db rasters to in-db rasters. This is
 the ST_MakeBandInDB(rast, band) function of Objective FV.18.

 Yes.  This is a missing feature.  For 2.1 in my opinion.
