Tom Lane 452b637d4b Adjust new test case for more portability. 
Early returns from the buildfarm say that most critters are good with
commit cbdb8b4c0, but gaur gives unexpected results with the test case
involving a float8 that's one-ULP-less-than-2^63.  It appears that that
platform's version of rint() rounds that value up to 2^63 instead of
leaving it be.  This is possibly a bug, and it's also possible that no
other platform anybody is using anywhere behaves likewise.  Still, the
point of the test is not to insist that everybody's rint() behaves exactly
the same.  Let's use two-ULPs-less-than-2^63 instead, which I've tested
to act the same on gaur as on more modern hardware.

(This is, more or less, exactly the portability issue I'd feared might
arise...)

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/.
