Greetings, As outlined in the commit message, this adds support for restrictive RLS policies. We've had this in the backend since 9.5, but they were only available via hooks and therefore extensions. This adds support for them to be configured through regular DDL commands. These policies are, essentially "AND"d instead of "OR"d.
Includes updates to the catalog, grammer, psql, pg_dump, and regression tests. Documentation will be added soon, but until then, would be great to get feedback on the grammer, catalog and code changes. Thanks! Stephen

Subject: [PATCH] Add support for restrictive RLS policies
We have had support for restrictive RLS policies since 9.5, but they
were only available through extensions which use the appropriate hooks.
This adds support into the grammer, catalog, psql and pg_dump for
restrictive RLS policies, thus reducing the cases where an extension is
necessary.
