In the case of an awful lot of polygonal (dimension==2) data this makes it necessary to use GEOMETRY (because so much data contains MULTIPOLYGONS as well as POLYGONS, eg any dataset of the countries of the world). If the type constraints could also, optionally, be dimension==0 (ie POINT or MULTIPOINT), dimension==1 (ie LINESTRING or MULTILINESTRING) or dimension==2 (ie POLYGON or MULTIPOLYGON), then GEOMETRY would not have to be used so frequently. Newer geometry types could also be added to the relevant constraint, eg CURVEPOLYGON to dimension==2, TIN to dimension==3, etc.",enhancement,new,low,PostGIS Fund Me,postgis,master,,,
