sqlc.slice() doesn't work with composite keys

[b3lrog]

Version

1.30.0

What happened?

The included schema and query generates a function with this signature:
func (q *Queries) ListAttachmentsByReplySlice(ctx context.Context) ([]ListAttachmentsByReplySliceRow, error)
This is pretty useless as I can't pass in my params. Not tried running it but I assume it either errors or returns a nil slice.

I was expecting sqlc to instead generate a struct like:

type ListAttachmentsByReplySliceParams struct {
	ThreadID  uint32
	ReplyID uint32
}

and a function using that struct like:
func (q *Queries) ListAttachmentsByReplySlice(ctx context.Context, replyKeys []ListAttachmentsByReplySliceParams) ([]ListAttachmentsByReplySliceRow, error)

Relevant log output

Database schema

CREATE TABLE `threads` (
  `thread_id` INT UNSIGNED NOT NULL AUTO_INCREMENT,
  `title` TEXT NOT NULL,
  PRIMARY KEY (`thread_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

CREATE TABLE `replies` (
  `thread_id` INT UNSIGNED NOT NULL,
  `reply_id` INT UNSIGNED NOT NULL,
  `comment` TEXT NOT NULL,
  PRIMARY KEY (`thread_id`,`reply_id`),
  FOREIGN KEY (`thread_id`)
    REFERENCES threads(`thread_id`)
    ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

CREATE TABLE `attachments` (
  `thread_id` INT UNSIGNED NOT NULL,
  `reply_id` INT UNSIGNED NOT NULL,
  `attachment_id` INT UNSIGNED NOT NULL,
  `file_path` TEXT NOT NULL,

SQL queries

-- name: ListAttachmentsByReplySlice :many
SELECT attachments.*
FROM attachments
WHERE (attachments.thread_id, attachments.reply_id) IN (sqlc.slice(reply_keys))
ORDER BY attachments.thread_id ASC, attachments.reply_id ASC, attachments.attachment_id ASC;
