This has to do with the way the JOIN currently functions. At the moment the JOIN nodes record an alias which has all columns listed, which is appropriately picked up by the dependency code. Tom is debating whether or not the alias on columns not used in the where or clause or returned is strictly necessary. Indeed, if you delete the dependencies, then drop the column the view continues to function but I'm not sure thats always the case. -- Rod Taylor ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
