Magnus Hagander 4eb77d50c2 Validate page level checksums in base backups
When base backups are run over the replication protocol (for example
using pg_basebackup), verify the checksums of all data blocks if
checksums are enabled. If checksum failures are encountered, log them
as warnings but don't abort the backup.

This becomes the default behaviour in pg_basebackup (provided checksums
are enabled on the server), so add a switch (-k) to disable the checks
if necessary.

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/.
