Michael Paquier 13b58f8934 Improve failure detection with array parsing in pg_dump 
Similarly to 3636efa, the checks done in pg_dump when parsing array
values from catalogs have been too lax.  Under memory pressure, it could
be possible, though very unlikely, to finish with dumps that miss some
data like:
- Statistics for indexes
- Run-time configuration of functions
- Configuration of extensions
- Publication list for a subscription

No backpatch is done as this is not going to be a problem in practice.
For example, if an OOM causes an array parsing to fail, a follow-up code
path of pg_dump would most likely complain with an allocation failure
due to the memory pressure.

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/.
