Just to be clear, I'm not ignoring this, I've been working to try and
rework the RLS documentation to add more information to the main RLS
section and to better segregate out the general RLS documentation out
from what should really be on the CREATE POLICY page.

This update will be incorporated into that and I'll be posting the whole
thing to -docs soon for comment.
