Tom Lane 49ac4039b2 Simplify view-expansion code in rewriteHandler.c. 
In the wake of commit 50c6bb022, it's not necessary for ApplyRetrieveRule
to have a forUpdatePushedDown parameter.  By the time control gets here for
any given view-referencing RTE, we should already have pushed down the
effects of any FOR UPDATE/SHARE clauses affecting the view from outer query
levels.  Hence if we don't find a RowMarkClause at the current query level,
that's sufficient proof that there is no outer one either.  This in turn
means we need no forUpdatePushedDown parameter for fireRIRrules.

I wonder whether we oughtn't also revert commit cba2d2717, since it now
seems likely that that was band-aiding around the bad effects of doing
FOR UPDATE pushdown and view expansion in the wrong order.  However,
in the absence of evidence that the current coding of markQueryForLocking
is actually buggy (i.e. missing RTEs it ought to mark), it seems best to
leave it alone.

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/.
