Generate a simplified polygon

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:

X > 0 will give a polygon bigger than the original geometry, and guaranteed to contain it.
X = 0 will give a polygon similar to the original geometry.
X < 0 will give a polygon smaller than the original geometry, and guaranteed to be smaller.

SQL requests:

X > 0: ST_Union(ST_MakeValid(ST_SimplifyPreserveTopology(geom, 0.00001)), ST_Buffer(ST_SimplifyPreserveTopology(ST_SnapToGrid(ST_Buffer(geom, X), Y), Z)))
X = 0: ST_Buffer(ST_SimplifyPreserveTopology(ST_SnapToGrid(ST_Buffer(geom, X), Y), Z)))
X < 0: ST_Intersection(geom, ST_Buffer(ST_SimplifyPreserveTopology(ST_SnapToGrid(ST_Buffer(geom, X), Y), Z)))
