You need to present a more convincing use-case than this unsupported
assertion. There's hardly any effective difference between a unique
index + NOT NULL constraints and a declared primary key ... so what
did you really need it for?

using non-default opclasses (which might have a surprising definition of
"equal"), and not already owned by a constraint ... not to mention that
it'd better be an index on the named table, which among other things
removes the need for a schema specification on the index name.
