Hello. In PostGIS online user manual's 4.2.1 "The SPATIAL_REF_SYS Table"( http://postgis.refractions.net/docs/ch04.html#id3176927), it described availability of "a listing of EPSG projection codes and their corresponding WKT representations" in http://www.opengis.org/techno/interop/EPSG2WKT.TXT. However this URL now doesn't exist. Does anyone know current URL of this info? Regards.
