suggestion: add post_name (aka slug) as a column option

[hughc]

I'm likely to be an edge case, but I've been rendering blocks on the fly in my templates, via simple function:

function renderBlockById($id) {
  // get reusable gutenberg block:
  $gblock = get_post($id);
  return apply_filters('the_content', $gblock->post_content);
}

In the interests of more readable code, I'd prefer to be passing the 'slug' of a block into this function, but the only place I can get them is from the database itself. Any chance it could be added as an optional column?
