Michael Paquier 8ef9451f58 Refactor cluster.c to use new routine get_index_isclustered() 
This new cache lookup routine has been introduced in a40caf5, and more
code paths can directly use it.

Note that in cluster_rel(), the code was returning immediately if the
tuple's entry in pg_index for the clustered index was not valid.  This
commit changes the code so as a lookup error is raised instead,
something that could not happen from the start as we check for the
existence of the index beforehand, while holding an exclusive lock on
the parent table.

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/.
