1319,"[raster] Make raster_columns a constraint-based view, replace AddRasterColumn with AddRasterConstraints and expand # of constraints on raster columns",robe,dustymugs,"All are we in agreement on this -ditch the raster_columns table and replace with a view that reads from table constraints. We will make raster_columns a view that reads the properties from the constraints on the tables.

constraints in mind so far SRID, band types, scale x, scale y.

The other change to make this useful which I think we discussed and including in this ticket is to have 

AddRasterColumns enforce band types which will provide the necessary info and enforcement of band types, num bands for the raster_columns table)

Please add to this other columns we will be keeping.

Just like geometry, people have the choice of relaxing constraints and those will just appear as NULL in the view or in case of SRID our unknown.",task,closed,critical,PostGIS 2.0.0,raster,trunk,fixed,,mateusz@…
