Tom Lane 0c62356cc8 Add an assertion that we don't pass NULL to snprintf("%s"). 
Per commit e748e902d, we appear to have little or no coverage in the
buildfarm of machines that will dump core when asked to printf a
null string pointer.  Let's try to improve that situation by adding
an assertion that will make src/port/snprintf.c behave that way.
Since it's just an assertion, it won't break anything in production
builds, but it will help developers find this type of oversight.

Note that while our buildfarm coverage of machines that use that
snprintf implementation is pretty thin on the Unix side (apparently
amounting only to gaur/pademelon), all of the MSVC critters use it.

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/.
