Tomas Vondra e72910f808 Fix handling of multi-column BRIN indexes 
When evaluating clauses on multiple scan keys of a multi-column BRIN
index, we can stop processing as soon as we find a scan key eliminating
the range, and the range should not be added to tbe bitmap.

That's how it worked before 14, but since a681e3c107 the code treated
the range as matching if it matched at least the last scan key.

Backpatch to 14, where this code was introduced.

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/.
