You can't drop foreign keys using the DROP CONSTRAINT command. If you read
the docs properly, you'll see that that is mentioned. You will have to
manuall drop all three triggers involved in the FK constraint. (2 on the
parent relation and 1 on the child)
Yes, this is a big deficiency in Postgres, but it's tricky to implement and
no-one's gotten around to it yet.
