You're living in a dream world if you think that works reliably in *any* version of Postgres. But for starters, what is your definition of "selected" --- pulled from the physical table?

Delivered N times to the client due to joining N times to some other table? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
