Hi all, I have a table with a MULTIPOLYGON field with around 100k records. Some of these records, 2K have self intersections and other problems that make ST_IsValid return false. The polygons overlap a lot and I wanted to generate another table that will be the union of all polygons.
The table looks like id, the_geom What would be the best way to union all of the geometries into a new table where there is only POLYGONS that do not overlap? Thanks in advance.
