Hey
I want to work towards the follwing feature in TODO list:
Prevent index uniqueness checks when UPDATE does not modify the column
Uniqueness (index) checks are done when updating a column even if the column is not modified by the UPDATE. However, HOT already short-circuits this in common cases, so more work might not be helpful.
 
So I wanted to know if someone is already working on this.
 
Thanks
Abhinav Batra
