Tom Lane 1804185c2d Doc: improve description of allowed spellings for Boolean input.
datatype.sgml failed to explain that boolin() accepts any unique
prefix of the basic input strings.  Indeed it was actively misleading
because it called out a few minimal prefixes without mentioning that
there were more valid inputs.

I also felt that it wasn't doing anybody any favors by conflating
SQL key words, valid Boolean input, and string literals containing
valid Boolean input.  Rewrite in hopes of reducing the confusion.

Per bug #15836 from Yuming Wang, as diagnosed by David Johnston.
Back-patch to supported branches.

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
