 I'm sorry, but IMHO you simply don't understand the purpose of this
 format.
 The flag if data is stored in-database or out-database is for sole use by
 the raster implementation in PostGIS. It is for PostGIS to be able to
 locate physical storage, not for client (user of public SQL API). It is
 not even of interested of any client. Fullstop.
