Noah Misch 79e0f87a15 Use type "int64" for memory accounting in tuplesort.c/tuplestore.c. 
Commit 263865a489 switched tuplesort.c and
tuplestore.c variables representing memory usage from type "long" to
type "Size".  This was unnecessary; I thought doing so avoided overflow
scenarios on 64-bit Windows, but guc.c already limited work_mem so as to
prevent the overflow.  It was also incomplete, not touching the logic
that assumed a signed data type.  Change the affected variables to
"int64".  This is perfect for 64-bit platforms, and it reduces the need
to contemplate platform-specific overflow scenarios.  It also puts us
close to being able to support work_mem over 2 GiB on 64-bit Windows.

Per report from Andres Freund.

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:

	http://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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
