Robert Haas 5a1007a508 Have the server properly terminate tar archives. Earlier versions of PostgreSQL featured a version of pg_basebackup that wanted to edit tar archives but was too dumb to parse them properly. The server made things easier for the client by failing to add the two blocks of zero bytes that ought to end a tar file, leaving it up to the client to do that. But since commit `23a1c6578c`, we don't need this hack any more, because pg_basebackup is now smarter and can parse tar files even if they are properly terminated! So change the server to always properly terminate the tar files. Older versions of pg_basebackup can't talk to new servers anyway, so there's no compatibility break. On the pg_basebackup side, we see still need to add the terminating zero bytes if we're talking to an older server, but not when the server is v15+. Hopefully at some point we'll be able to remove some of this compatibility cruft, but it seems best to hang on to it for now. In passing, add a file header comment to bbstreamer_tar.c, to make it clearer what's going on here.

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/.
