<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
|
|
database. Thus, it might be more convenient to use the program
|
|
<xref linkend="app-dropdb" endterm="app-dropdb-title"> instead,
|
|
which is a wrapper around this command.
