Tom Lane e99010cbd8 pg_dump: provide a stable sort order for rules. 
Previously, we sorted rules by schema name and then rule name;
if that wasn't unique, we sorted by rule OID.  This can be
problematic for comparing dumps from databases with different
histories, especially since certain rule names like "_RETURN"
are very common.  Let's make the sort key schema name, rule name,
table name, which should be unique.  (This is the same behavior
we've long used for triggers and RLS policies.)

Andreas Karlsson

This back-patches v18 commit 350e6b8ea8 to
all supported branches.  The next commit will assert that pg_dump
provides a stable sort order for all object types.  That assertion would
fail without stabilizing DO_RULE order as this commit did.

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/.
