Ability to clone query/filter builders

[EskiMojo14]

I'd like to do something like the below (I'm actually using RTKQ, but this example will use Tanstack Query for brevity):

const getPostsQuery = supabase.from("posts").select(`
  id,
  author:profiles(name),
  content
`);
export type Post = QueryData<typeof getPostsQuery>[number]

export const getPosts = queryOptions({
  queryKey: ["posts"],
  queryFn: () => getPostsQuery
})

export const getPostById = (id: Post["id"]) => queryOptions({
  queryKey: ["posts", id],
  queryFn: () => getPostsQuery.eq("id", id).single()
})

But from what I can tell, this would be unsafe as the filter methods mutate the original instance.

If builders had a clone method, it would be possible to explicitly avoid mutating the original:

getPostsQuery.clone().eq("id", id).single();

Open to other suggestions :)
