Tom Lane 86ffdcad1b Remove the special cases to prevent minus-zero results in float4 and float8 unary minus operators. We weren't attempting to prevent minus zero anywhere else; in view of our gradual trend to make the float datatypes more IEEE standard compliant, we should allow minus zero here rather than disallow it elsewhere. We don't, however, expect that all platforms will produce minus zero, so we need to adjust the one affected regression test to allow both results. Per discussion of bug #4660. (In passing, clean up a couple other minor infelicities in float.c.)		2009-02-18 19:23:26 +00:00

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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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/.
