My PL/PGSQL fu is lacking and I'm not sure what Sandro means in details,
but is it possible to store static constant values within a constraint?
If it is possible, then storing the two hard-coded float-point numbers
of real spatial extent of the whole raster table coverage would do the trick,
and without touching headers of individual rasters in rows.
