Robert Haas 45f5c81ad2 Fix failure to advance content pointer in sendFileWithContent. 
If sendFileWithContent were used to send a file larger than the
bbsink buffer size, this would result in corruption. The only
files that are sent via sendFileWithContent are the backup label
file, the tablespace map file, and .done files for WAL segments
included in the backup. Of these, it seems that only the
tablespace_map file can become large enough to cause a problem,
and then only if you have a lot of tablespaces. If you do have
that situation, you might end up with a corrupted
tablespace_map file, which would be bad.

My commit bef47ff85d introduced
this problem.

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/.
