#3441: [raster] Create out-db file using ST_AddBand
--------------------------------+---------------------------
 Reporter:  gdrolet             |      Owner:  dustymugs
     Type:  enhancement         |     Status:  new
 Priority:  medium              |  Milestone:  PostGIS 2.3.0
Component:  raster              |    Version:  trunk
 Keywords:  ST_AddBand, out-db  |
--------------------------------+---------------------------
 Following the examples in the manual, I wanted to create a new out-db file
 using ST_AddBand:

 {{{
 SELECT ST_AddBand(
         ST_MakeEmptyRaster(10, 10, 0, 0, 50), 1,
         'E:\Temp\mytestraster.tif'::text, ARRAY[]::integer[]);
 }}}

 Which returns with this error:

 {{{
 ERROR:  RASTER_addBandOutDB: Could not open out-db file with GDAL
 ********** Error **********
 }}}

 After checking that the permissions on the path are ok, I realized that
 the out-db file must already exist somewhere in the system for the query
 to work (or am I wrong?).

 I think it would be nice if we had the possibility to create a new raster
 file (registered as an out-db file in the database) using the query above
 or something similar.

 PostGIS version:

 }}}
