No it is strongly typed, there is no accident that all PL extensions to the base query language have such a Ada/Pascal similarity.
Additional DML has plenty of options to enforce rules that keep data consistency.
While they make the life harder to delete/update/insert items in specific sequences, they can save the day on bad queries.
What happens if a query compares a string to a number?
You get a type error from the database.
