Flash-backing on this one:

Markus M:
Yes, overlapping areas can be represented as a topological model
through M:N mapping: each area can belong to several categories,
several areas can have the same category. If you want to get the
coverage for a particular Landsat scene, just select the path and row
with where="PATH = x and row = y". See also the manual of v.buffer
for
a similar example.
So, I guess I'll forget the idea to fully automatise the process of
Landsat border trimming? Can't we just have all of the Path-Row tiles
ready in a compressed GRASS format? Some sort of packed ASCII file which
can be easily imported? No other ideas?

Markus N:
Hence, you need to maintain them (AFAIK it is the -c option in
v.in.ogr).
Please correct me if I am wrong.
For this shapefile, original polygons can not be maintained
(incorrect
boundaries, centroids exceeding number of areas).
