Tom Lane 242066cc8e Speed up "brin" regression test a little bit. 
In the large DO block, collect row TIDs into array variables instead of
creating and dropping a pile of temporary tables.  In a normal build,
this reduces the brin test script's runtime from about 1.1 sec to 0.4 sec
on my workstation.  That's not all that exciting perhaps, but in a
CLOBBER_CACHE_ALWAYS test build, the runtime drops from 20 min to 17 min,
which is a little more useful.  In combination with some other changes
I plan to propose, this will help provide a noticeable reduction in
cycle time for CLOBBER_CACHE_ALWAYS buildfarm critters.

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.  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/.
