These variables no longer have any useful purpose, since there's no reason to special-case brute force timezones now that we have a valid session_timezone setting for them. Remove the variables, and remove the SET/SHOW TIME ZONE code that deals with them. The user-visible impact of this is that SHOW TIME ZONE will now show a POSIX-style zone specification, in the form "<+-offset>-+offset", rather than an interval value when a brute-force zone has been set. While perhaps less intuitive, this is a better definition than before because it's actually possible to give that string back to SET TIME ZONE and get the same behavior, unlike what used to happen. We did not previously mention the angle-bracket syntax when describing POSIX timezone specifications; add some documentation so that people can figure out what these strings do. (There's still quite a lot of undocumented functionality there, but anybody who really cares can go read the POSIX spec to find out about it. In practice most people seem to prefer Olsen-style city names anyway.) |

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/.
