However, I'm curious about where your definition of views comes from. My understanding is that update-able views were concepts of Codd's original relational model and such views are also part of the SQL standard. And since "PostgreSQL prides itself in standards compliance...," (http://www.postgresql.org/about/) I wouldn't expect to see update-able views on the features *not* to do list any time soon. (http://wiki.postgresql.org/wiki/Todo#Features_We_Do_Not_Want) Although I do see planner hints are one of the features listed there. -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug
