Andrew Dunstan a6baa4badd Documentation for SQL/JSON features
This documents the features added in commits f79b803dcc, f4fb45d15c,
33a377608f, 1a36bc9dba, 606948b058, 49082c2cc3, 4e34747c88, and
fadb48b00e.

I have cleaned up the aggregate section of the submitted docs, but there
is still a deal of copy editing required. However, I thought it best to
have some documentation sooner rather than later so testers can have a
better idea what they are playing with.

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:

	https://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
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
