Noah Misch 4664de1826 Test restartpoints in archive recovery. 
v14 commit 1f95181b44 and its v13
equivalent caused timing-dependent failures in archive recovery, at
restartpoints.  The symptom was "invalid magic number 0000 in log
segment X, offset 0", "unexpected pageaddr X in log segment Y, offset 0"
[X < Y], or an assertion failure.  Commit
3635a0a35a and predecessors back-patched
v15 changes to fix that.  This test reproduces the problem
probabilistically, typically in less than 1000 iterations of the test.
Hence, buildfarm and CI runs would have surfaced enough failures to get
attention within a day.

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/.
