Because no one's ever bothered to work on them. You should talk to the PostGIS guys, however, because they *have* been working on real statistics and real estimation functions for geometric types. It'd be nice to get some of that work back-ported into the core database. http://www.postgis.org/ regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
