sqlc.narg ignored with array cast

What happened?

In the playground example I supplied, you can see that I have used both sqlc.arg and sqlc.narg when casting to TEXT[], but the generated code does not contain sql.NullString for the second argument as I expected.

Input:

-- name: batchUpsert :exec
INSERT INTO authors (id, name, bio)
VALUES (
  unnest(sqlc.arg(ids)::BIGINT[]),
  unnest(sqlc.arg(names)::TEXT[]),
  unnest(sqlc.narg(bios)::TEXT[])
) ON CONFLICT (id) DO UPDATE SET
	name = EXCLUDED.name,
	bio = EXCLUDED.bio;

Output:

type batchUpsertParams struct {
	Ids   []int64
	Names []string
	Bios  []string
}

Expected:

type batchUpsertParams struct {
	Ids   []int64
	Names []string
	Bios  []sql.NullString
}

If I take away the array part of the cast, so ::TEXT instead of ::TEXT[], it seems to work as expected, so I assume that this is a bug, and not intentional.

If there are any other way to have a dynamic batching system someone could recommend, I will give that a try, but so far, this is what I have.

Thanks
