Fix some more bugs in foreign keys connecting partitioned tables 
* In DetachPartitionFinalize() we were applying a tuple conversion map
  to tuples that didn't need one, which can lead to erratic behavior if
  a partitioned table has a partition with a different column order, as
  reported by Alexander Lakhin. This was introduced by 53af9491a0.
  Don't do that.  Also, modify a recently added test case to exercise
  this.

* The same function as well as CloneFkReferenced() were acquiring
  AccessShareLock on a partition, only to have CreateTrigger() later
  acquire ShareRowExclusiveLock on it.  This can lead to deadlock by
  lock escalation, unnecessarily.  Avoid that by acquiring the stronger
  lock to begin with.  This probably dates back to branch 12, but I have
  never seen a report of this being a problem in the field.

* Innocuous but wasteful: also introduced by 53af9491a0, we were
  reading a pg_constraint tuple from syscache that we don't need, as
  reported by Tender Wang.  Don't.

Backpatch to 15.

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/.
