Jeff Davis edd9a2bf74 Fix assign_record_type_typmod().
If an error occurred in the wrong place, it was possible to leave an
unintialized entry in the hash table, leading to a crash. Fixed.

Also, be more careful about the order of operations so that an
allocation error doesn't leak memory in CacheMemoryContext or
unnecessarily advance NextRecordTypmod.

Backpatch through version 11. Earlier versions (prior to 35ea75632a)
do not exhibit the problem, because an uninitialized hash entry
contains a valid empty list.

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/.
