I'm doing the Todo List's "Allow VIEW/RULE recompilation when the underlying tables change ". I've a very simple idea that I save the "create view" query_string in systable. When I found that I select from a view, I drop the view and recreate the view by execute the source query_string. Then go on execute this "select from a view" and will get the right answer. My problem is that how could I get the orginal query which user typed to postgres?
Er, maybe drop and recreate the view is an ugly idea...Is there any better methods to do recompilation?
