INSERT with RETURNING does not work with prepared statement

[tbantle22]

An INSERT with RETURNING without a prepared statement returns the correct value without an error

postgres=> INSERT INTO public.test (id) VALUES (1) RETURNING id;
 id
----
  1
(1 row)

INSERT 0 1

But the same thing using a prepared statement errors with unable to find field with index 1 in row of 1 columns

INSERT INTO public.test (id) VALUES ($1) RETURNING id;

A similar query is used by PrismaJS
