Robert Haas f455e1125e Pass eflags down to parallel workers. 
Currently, there are no known consequences of this oversight, so no
back-patch.  Several of the EXEC_FLAG_* constants aren't usable in
parallel mode anyway, and potential problems related to the presence
or absence of OIDs (see EXEC_FLAG_WITH_OIDS, EXEC_FLAG_WITHOUT_OIDS)
seem at present to be masked by the unconditional projection step
performed by Gather and Gather Merge.  In general, however, it seems
important that all participants agree on the values of these flags,
which modify executor behavior globally, and a pending patch to skip
projection in Gather (Merge) would be outright broken in certain cases
without this fix.

Patch by me, based on investigation of a test case provided by Amit
Kapila.  This patch was also 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/.
