Michael Paquier 6b0208ebc4 Fix partition tuple routing with dropped attributes 
When trying to insert a tuple into a partitioned table, the routing to
the correct partition has been messed up by mixing when a tuple needs to
be stored in an intermediate parent's slot and when a tuple needs to be
converted because of attribute changes between the immediate parent
relation and the parent relation one level above that (the grandparent).
This could trigger errors like the following:
ERROR: cannot extract attribute from empty tuple slot SQL state: XX000

This was not detected because regression tests with dropped attributes
only included tests with two levels of partitioning, and this can be
triggered with three levels or more.

This fixes bug #15733, which has been introduced by 34295b8.  The bug
happens only on REL_11_STABLE and HEAD gains the regression tests added
for this bug.

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/.
