Re: Row Level Security Policies documentation doesn't mention lack of support for views

The CREATE VIEW documentation links to

https://www.postgresql.org/docs/9.6/static/rules-privileges.html

which covers this dynamic in considerable detail (and there is a blurb on
the CREATE VIEW page as well), and specifically:

"Relations that are used due to rules get checked against the privileges of
the rule owner, not the user invoking the rule."

It does feel like an additional blurb about views and a link to the above
page would be warranted on the ddl-rowsecurity.html page.
