Tom Lane 84eca14bc4 Remove ancient hacks to ignore certain opclass names in CREATE INDEX.
Twenty years ago, we removed certain operator classes in favor of
letting indexes over their data types be built with some other
binary-compatible, more standard opclass.  As a hack to allow existing
index definitions to be dumped and reloaded, we made CREATE INDEX ignore
the removed opclass names, so that such indexes would fall back to the
new default opclass for their data types.  This was never intended to
be a long-lived thing; it carries the obvious risk of breaking some
future developer's attempt to re-use those old opclass names.  Since
all of the cases in question are for opclasses that were removed
before PG 8.0, it seems okay to get rid of these hacks now.

This is part of a group of patches removing various server-side kluges
for transparently upgrading pre-8.0 dump files.  Since we've had few
complaints about dropping pg_dump's support for dumping from pre-8.0
servers (commit 64f3524e2), it seems okay to now remove these kluges.

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/.
