Tom Lane 07f69137b1 Fix building of large (bigger than shared_buffers) hash indexes. 
When the index is predicted to need more than NBuffers buckets,
CREATE INDEX attempts to sort the index entries by hash key before
insertion, so as to reduce thrashing.  This code path got broken by
commit 9f03ca9151, which overlooked that _hash_form_tuple() is not
just an alias for index_form_tuple().  The index got built anyway, but
with garbage data, so that searches for pre-existing tuples always
failed.  Fix by refactoring to separate construction of the indexable
data from calling index_form_tuple().

Per bug #14210 from Daniel Newman.  Back-patch to 9.5 where the
bug 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:

	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/.
