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.

<command>DROP DATABASE</command> drops a database. It removes the
|
|
catalog entries for the database and deletes the directory
|
|
containing the data. It can only be executed by the database owner.
|
|
Also, it cannot be executed while you or anyone else are connected
|
|
to the target database. (Connect to <literal>postgres</literal> or any
|
|
other database to issue this command.)

This command cannot be executed while connected to the target

|

<xref linkend="app-dropdb" endterm="app-dropdb-title"> instead,
|

which is a wrapper around this command.
