Tatsuo Ishii a16db3a07d Fix incorrect tps number calculation in "excluding connections establishing". 
The tolerance (larger than actual tps number) increases as the number
of threads decreases.  The bug has been there since the thread support
was introduced in 9.0. Because back patching introduces incompatible
behavior changes regarding the tps number, the fix is committed to
master and 9.5 stable branches only.

Problem spotted by me and fix proposed by Fabien COELHO. Note that his
original patch included more than fixes (a code re-factoring) which is
not related to the problem and I omitted the part.

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/.
