It's still under discussion, but the view is generated automatically by 
querying the system catalogues to pull out the spatial columns (i.e. it 
can't be altered, but users will be able to see other users' spatial 
columns in there).

This means that AddGeographyColumn() and DropGeometryColumn() can just 
add/remove the column from the table directly, so this can only happen 
on tables for which the current role has SQL permissions.
