Whoever is having problems with the extent now being larger than expected.
Is that the issue, right ?  

I see the extent in raster_columns is returned by:
_raster_constraint_info_extent(n.nspname, c.relname, a.attname) AS extent

Could that function figure if it's a "regular blocking" table by looking
at other constraints and encode padding in those constraints ?
