Michael Paquier 04cf0bfc90 Fix memory leak coming from simple lists built in reindexdb 
When building a list of relations for a parallel processing of a schema
or a database (or just a single-entry list for the non-parallel case
with the database name), the list is allocated and built on-the-fly for
each database processed, leaking after one database-level reindex is
done.  This accumulates leaks when processing all databases, and could
become a visible issue with thousands of relations.

This is fixed by introducing a new routine in simple_list.c to free all
the elements in a simple list made of strings or OIDs.  The header of
the list may be using a variable declaration or an allocated pointer,
so we don't have a routine to free this part to keep the interface
simple.

Per report from coverity for an issue introduced by 5ab892c, and
valgrind complains about the leak as well.  The idea to introduce a new
routine in simple_list.c is from Tom Lane.

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/.
