X, Y, Z are parameters for the following postgis equation. The default values are chosen according to the size of the original geometry to give a slighty bigger geometry, without too many nodes.
Note that:ST_Union(ST_MakeValid(ST_SimplifyPreserveTopology(geom, 0.00001)), ST_Buffer(ST_SimplifyPreserveTopology(ST_SnapToGrid(ST_Buffer(geom, X), Y), Z)))
ST_Buffer(ST_SimplifyPreserveTopology(ST_SnapToGrid(ST_Buffer(geom, X), Y), Z)))
ST_Intersection(geom, ST_Buffer(ST_SimplifyPreserveTopology(ST_SnapToGrid(ST_Buffer(geom, X), Y), Z)))
