Hello, Looking for advice on creating as dynamic a datalogging scheme as I can using plpgsql. The idea would be to have a trigger function that I could drop on any table in my database. Then on update, the function would iterate through each field, and check to see if NEW.<fieldname> <> OLD.<fieldname>. Then a function would be called that would insert data into a logging table. I can do this in a very static sense whereby each table has its own specific trigger function that specifies each column by name (NEW.co_name <> OLD.co_name), etc. But, this is pretty cumbersome, and as new columns are added, we would need to remember to go in and change the function. Running Postgresql 8.1 Thanks for any advice/help!
