Tom Lane fd582317e1 Sync our Snowball stemmer dictionaries with current upstream.
We haven't touched these since text search functionality landed in core
in 2007 :-(.  While the upstream project isn't a beehive of activity,
they do make additions and bug fixes from time to time.  Update our
copies of these files.

Also update our documentation about how to keep things in sync, since
they're not making distribution tarballs these days.  Fortunately,
their source code turns out to be a breeze to build.

Notable changes:

* The non-UTF8 version of the hungarian stemmer now works in LATIN2
not LATIN1.

* New stemmers have appeared for arabic, indonesian, irish, lithuanian,
nepali, and tamil.  These all work in UTF8, and the indonesian and
irish ones also work in LATIN1.

(There are some new stemmers that I did not incorporate, mainly because
their names don't match the underlying languages, suggesting that they're
not to be considered mainstream.)

Worth noting: the upstream Nepali dictionary was contributed by
Arthur Zakirov.

initdb forced because the contents of snowball_create.sql have
changed.

Still TODO: see about updating the stopword lists.

Arthur Zakirov, minor mods and doc work by me

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/.
