Alvaro Herrera b4da9d0e1e brin: Don't crash on auto-summarization
We were trying to free a pointer into a shared buffer, which never
works; and we were failing to release the buffer lock appropriately.
Fix those omissions.

While at it, improve documentation for brinGetTupleForHeapBlock, the
inadequacy of which evidently caused these bugs in the first place.

Reported independently by Zhou Digoal (bug #14668) and Alexander Sosna.

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:

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/.
