Hello, I am new to postgresql code, I would like to start implementing easyish TODO items. I have read most of the development guidelines, faqs, articles by Greg Smith (Hacking Postgres with UDFs, Adding WHEN to triggers).
The item I would like to implement is adding CORRESPONDING [BY (col1[,col2,...]])] to INTERSECT and EXCEPT operators. Can anyone comment on how much effort this item needs? regards, kerem kat.
