#1440: [raster] Support for offline band data
----------------------------+-----------------------------------------------
 Reporter:  dustymugs       |       Owner:  dustymugs    
     Type:  enhancement     |      Status:  new          
 Priority:  medium          |   Milestone:  PostGIS 2.0.0
Component:  postgis raster  |     Version:  trunk        
 Keywords:                  |  
----------------------------+-----------------------------------------------
 Add functionality to load offline bands so that the PostGIS raster
 functions can be used.  The data will be read-only instead of read-write
 due to several issues:

 1. filesystem privileges: will the user account that the postgres process
 have write access to the raster file and containing directory?

 2. offline raster format: does the format of the offline raster permit
 direct modification of a band value or is an intermediary format required?

 Once read-only access is complete, the out_db column of raster_columns
 view will be reintroduced.  In the new iteration of the out_db column, it
 will be an array of booleans where each element indicates that the band's
 data is offline.
