Seems to me that the behavior to not complete with COLUMN or
CONSTRAINT for ADD is intentional, as it is possible to specify a
constraint or column name without the object type first. This
introduces a inconsistent behavior with what we do for columns with
ADD, for one. So a more consistent approach would be to list columns,
constraints, COLUMN and CONSTRAINT in the list of options available
after ADD.

+ }
Specifying valid constraints is an authorized grammar, so it does not
seem that bad to keep things as they are, either. I would leave that
alone.
