Michael Paquier b30282fccf Fix incorrect memory context switch in COPY TO execution 
c532d15 has split the logic of COPY commands into multiple files, one
change being to move the internals of BeginCopy() to BeginCopyTo().
Originally the code was written so as we'd switch back-and-forth between
the current execution memory context and the dedicated memory context
for the COPY command, and this refactoring has introduced an extra
switch to the current memory context from the COPY context once
BeginCopyTo() is done with the past logic coming from BeginCopy().

The code was correctly doing the analyze, rewrite and planning phases in
the COPY context, but it was not assigning "copy_file" (FILE* used when
copying to a source file) and "filename" in the COPY context, making the
COPY status data inconsistent.

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/.
