Noah Misch 8222a9d9a1 In successful pg_recvlogical, end PGRES_COPY_OUT cleanly. 
pg_recvlogical merely called PQfinish(), so the backend sent messages
after the disconnect.  When that caused EPIPE in internal_flush(),
before a LogicalConfirmReceivedLocation(), the next pg_recvlogical would
repeat already-acknowledged records.  Whether or not the defect causes
EPIPE, post-disconnect messages could contain an ErrorResponse that the
user should see.  One properly ends PGRES_COPY_OUT by repeating
PQgetCopyData() until it returns a negative value.  Augment one of the
tests to cover the case of WAL past --endpos.  Back-patch to v10, where
commit 7c030783a5 first appeared.  Before
that commit, pg_recvlogical never reached PGRES_COPY_OUT.

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/.
