Tom Lane 162477a63d Doc: improve documentation about inheritance. 
Clarify documentation about inheritance of check constraints, in
particular mentioning the NO INHERIT option, which didn't exist when
this text was written.

Document that in an inherited query, the applicable row security policies
are those of the explicitly-named table, not its children.  This is the
intended behavior (per off-list discussion with Stephen Frost), and there
are regression tests for it, but it wasn't documented anywhere user-facing
as far as I could find.

Do a bit of wordsmithing on the description of inherited access-privilege
checks.

Back-patch to 9.5 where RLS was added.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	http://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
