Something else I noticed: the error message from ALTER TABLE ... ADD
CONSTRAINT in the case of a duplicate constraint name is not very
friendly:

ERROR:  duplicate key value violates unique constraint
"pg_constraint_conrelid_contypid_conname_index"
DETAIL:  Key (conrelid, contypid, conname)=(16540, 0, nn) already exists.

To match the error message for other constraint types, this should be:

ERROR:  constraint "nn" for relation "foo" already exists

Dean
