Nathan Bossart 411b720343 Teach in-tree getopt_long() to move non-options to the end of argv. 
Unlike the other implementations of getopt_long() I could find, the
in-tree implementation does not reorder non-options to the end of
argv.  Instead, it returns -1 as soon as the first non-option is
found, even if there are other options listed afterwards.  By
moving non-options to the end of argv, getopt_long() can parse all
specified options and return -1 when only non-options remain.
This quirk is periodically missed by hackers (e.g., 869aa40a27,
ffd398021c, and d9ddc50baf).  This commit introduces the
aforementioned non-option reordering behavior to the in-tree
getopt_long() implementation.

Special thanks to Noah Misch for his help verifying behavior on
AIX.

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/.
