Tom Lane a7ef273e1c Fix calculation of maximum statistics-message size. 
The PGSTAT_NUM_TABENTRIES macro should have been updated when new fields
were added to struct PgStat_MsgTabstat in commit 644828908, but it wasn't.
Fix that.

Also, add a static assertion that we didn't overrun the intended size limit
on stats messages.  This will not necessarily catch every mistake in
computing the maximum array size for stats messages, but it will catch ones
that have practical consequences.  (The assertion in fact doesn't complain
about the aforementioned error in PGSTAT_NUM_TABENTRIES, because that was
not big enough to cause the array length to increase.)

No back-patch, as there's no actual bug in existing releases; this is just
in the nature of future-proofing.

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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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/.
