comment Get Lon Lat values from a GEOGRAPHY data type in PostGIS
Even PostGIS 2.2 have no ST_X(geography ), see postgis.net/docs/manual-2.2/ST_X.html

For geography datatype use valid function, ex. ST_MaxX() and ST_MaxY().

comment Create mosaic like Voronoi Diagram from disjoint polygons
Nice solution (!), and thanks the illustration. Can you enhance it? See the left rectangle below, it was 4 points at Voronoi, and the center of rectangle have no representantion, distorting its region (losting are to the triangle)... Perhaps enhance is possible doing a regular sampling of each polygon... and perhaps also some interior points.

add "the problem" link and remember that transformed into a disjoint-polygons-problem

comment Create mosaic like Voronoi Diagram from disjoint polygons
Thanks @Nir, sorry the confusion with points, I am not using points, only polygons as items (a) and (b) of the illustration... Do you have a link of your clue about solution?

comment Updating SRID (Update_GeometrySRID) does not alter polygons (when it should)
Do you check if external georegister procedure can make your shapefiles fit to the expected positions? (ex. using 5 control points can get good fit)
