Tom Lane dc227eb82e Add a build-time check that libpq doesn't call exit() or abort(). 
Directly exiting or aborting seems like poor form for a general-purpose
library.  Now that libpq liberally uses bits out of src/common/,
it's very easy to accidentally include code that would do something
unwanted like calling exit(1) after OOM --- see for example 8ec00dc5c.
Hence, add a simple cross-check that no such calls have made it into
libpq.so.

The cross-check depends on nm(1) being available and being able to
work on a shared library, which probably isn't true everywhere.
But we can just make the test silently do nothing if nm fails.
As long as the check is effective on common platforms, that should
be good enough.  (By the same logic, I've not worried about providing
an equivalent test in MSVC builds.)

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/.
