Hi,
Martin

I'm interest too to details for GriddedUnion.

I'm having same problem of Giovanni, using ST_Union on a lot of data and it
give me same exceptions.
Now I partially resolve using ST_Collect , but it give me other problems and
because I like to have boundaries fusion I would prefer using the ST_Union.

So I like to understand better this option of GriddedUnion..

Thx,

Andrea.
