Tom Lane f26c06a404 Fix error-cleanup mistakes in exec_stmt_call(). 
Commit 15c729347 was a couple bricks shy of a load: we need to
ensure that expr->plan gets reset to NULL on any error exit,
if it's not supposed to be saved.  Also ensure that the
stmt->target calculation gets redone if needed.

The easy way to exhibit a problem is to set up code that
violates the writable-argument restriction and then execute
it twice.  But error exits out of, eg, setup_param_list()
could also break it.  Make the existing PG_TRY block cover
all of that code to be sure.

Per report from Pavel Stehule.

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/.
