Michael Paquier 2d7d67cc74 Fix random regression failure in test case "temp" 
This test case could fail because of an incorrect result ordering when
looking up at pg_class entries.  This commit adds an ORDER BY to the
culprit query.  The cause of the failure was likely caused by a plan
switch.  By default, the planner would likely choose an index-only scan
or an index scan, but even a small change in the startup cost could have
caused a bitmap heap scan to be chosen, causing the failure.

While on it, switch some filtering quals to a regular expression as per
an idea of Tom Lane.  As previously shaped, the quals would have
selected any relations whose name begins with "temp".  And that could
cause failures if another test running in parallel began to use similar
relation names.

Per report from buildfarm member anole, though the failure was very
rare.  This test has been introduced by 319a810, so backpatch down to
v10.

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/.
