There are several variants of this function. maximumnumber of decimal places used in output (defaults to 15) and version default to 2.Version 1: ST_AsKML(geom) / version=2 precision=15Version 2: ST_AsKML(geom, max_sig_digits) / version=2Version 3: ST_AsKML(version, geom) / precision=15Version 4: ST_AsKML(version, geom, precision)NoteRequires PostGIS be compiled with Proj support. Use PostGIS_Full_Version to confirm you have proj support compiledin.NoteAvailability: 1.2.2 - later variants that include version param came in 1.3.2NoteAsKML output will not work with geometries that do not have an SRIDThis function supports 3d and will not drop the z-index.ExamplesSELECT ST_AsKML(ST_GeomFromText(’POLYGON((0 0,0 1,1 1,1 0,0 0))’,4326));st_askml--------0,0 0,1 1,1 1,0 0,0
