Yep... that was my surprise.

I don't have a time machine to be absolutely sure about what I did
but I should have created a pk on both machines with a
create table shop_commerce_gift(
  giftcode varchar primary key
...
);

but in the newer pg I actually find the pk constraint... in the
older I find a not null + an unique index with a different name from
the pk name of the former.
