unlike template0 and template1 does not have any special status in terms of backend functionality. However, all external utilities such as createuser and createdb now connect to "postgres" instead of template1, and the documentation is changed to encourage people to use "postgres" instead of template1 as a play area. This should fix some longstanding gotchas involving unexpected propagation of database objects by createdb (when you used template1 without understanding the implications), as well as ameliorating the problem that CREATE DATABASE is unhappy if anyone else is connected to template1. Patch by Dave Page, minor editing by Tom Lane. All per recent pghackers discussions.
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. The JDBC, ODBC, C++, Python, and Tcl interfaces have been moved to the PostgreSQL Projects Web Site at http://gborg.postgresql.org for separate maintenance. A Perl DBI/DBD driver is available from CPAN. 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 ftp://ftp.postgresql.org/pub/. For more information look at our web site located at http://www.postgresql.org/.
