Heikki Linnakangas 34ebeb15c8 Don't allow composite type to be member of itself via multirange
CheckAttributeType() checks that a composite type is not made a member
of itself with ALTER TABLE ADD COLUMN or ALTER TYPE ADD ATTRIBUTE,
even indirectly via a domain, array, another composite type or a range
type. But it missed checking for multiranges. That was a simple
oversight when multiranges were added.

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/.
