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. -- ----------------- Andrea Peri . . . . . . . . . qwerty àèìòù -----------------
