Fix end LSN determination in recently added test 
The test added in commit e44dae07f9 has a thinko: it wants to read
info about a few WAL records, but it obtains the LSN of the final record
to read by asking for the WAL insert position; however,
pg_get_wal_records_info only accepts to read up to the flush position
(cf. IsFutureLSN()).  In normal conditions there is no difference, since
the last record written by the preceding loop is known flushed and it's
the one the test wants; but it's possible to have some other process
insert another WAL record that isn't flushed, and that causes the whole
test to explode.

Fix by having pg_get_wal_records_info() read only up to the flushed
position.  Backpatch to 15, which is where pg_walinspect appeared.

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/.
