Just an update to let list users know that the call to cleangeometry() did return after a very long time--almost 17 hours for one of my files and more than a day for another.

There are many possibly kind of invalidity. If the invalidity is a self-intersect, of course the ST_MakeValid() could split the polygon on the self-intersect and produce another multipolygon with one more part. But if , for example, you multipolygon is invalid because it has a hole of type Linestring, or because it has two part that are touching along a line. More probably the st_makevalid could be return a geometrycollection(). -- ----------------- Andrea Peri . . . . . . . . . qwerty àèìòùo -----------------
