Robert Haas 0510421ee0 Tweak use of ExecContextForcesOids by Gather (Merge). 
Specifically, pass the outer plan's PlanState instead of our own
PlanState.  At present, ExecContextForcesOids doesn't actually care
which PlanState we pass; it just looks through to the underlying
EState to find the result relation or top-level eflags.  However, in
the future it might care.  If that happens, and if our goal is to get
a tuple descriptor that matches that of the outer plan, then I think
what we care about is whether the outer plan's context forces OIDs,
rather than whether our own context forces OIDs, just as we use the
outer node's target list rather than our own.

Patch by me, reviewed by Amit Kapila.

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/.
