-- You can reduce storage space for unneeded geometries and optimize query optimizations by applying the PostGIS [`ST_Simplify`](http://www.postgis.org/docs/ST_Simplify.html) function. For example, you can simplify the `the_geom` for a large table of polygons and reduce the size of them for quicker rendering.
