Hi Everyone, Given a table "Items" with a PK "item1" and "Qty" - a numeric column I'd like to define a way in Postgres to insert when item11 doesn't exist already in "Items" and update the Qty by adding the new quantity to the existent when the item11 exists. What is a good approach and where should I be looking for details. Thanks.
