Tom Lane f9278cb0ae Doc: fix out-of-date example of SPI usage. 
The "count" argument of SPI_exec() only limits execution when
the query is actually returning rows.  This was not the case
before PG 9.0, so this example was correct when written; but
we missed updating it in commit 2ddc600f8.  Extend the example
to show the behavior both with and without RETURNING.

While here, improve the commentary and markup for the rest
of the example.

David G. Johnston and Tom Lane, per report from Curt Kolovson.
Back-patch to all supported branches.

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/.
