how do i run a query like `SELECT SUM(column) FROM tablename` with supabase-js?

```js
const { count, error } = await supabase
  .from('tablename')
  .select('*', { head: true, count: 'exact' })
```

I think the question was sum (like add all the numbers in a column) versus just count how many columns

Ah good catch, yes you would have to create a view for this.
