Tom Lane 792213f2e9 Correctly update hasSubLinks while mutating a rule action. 
rewriteRuleAction neglected to check for SubLink nodes in the
securityQuals of range table entries.  This could lead to failing
to convert such a SubLink to a SubPlan, resulting in assertion
crashes or weird errors later in planning.

In passing, fix some poor coding in rewriteTargetView:
we should not pass the source parsetree's hasSubLinks
field to ReplaceVarsFromTargetList's outer_hasSubLinks.
ReplaceVarsFromTargetList knows enough to ignore that
when a Query node is passed, but it's still confusing
and bad precedent: if we did try to update that flag
we'd be updating a stale copy of the parsetree.

Per bug #17972 from Alexander Lakhin.  This has been broken since
we added RangeTblEntry.securityQuals (although the presented test
case only fails back to 215b43cdc), so back-patch all the way.

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/.
