<title>Description</title>
<para>
<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.)
</para>
<para>
<command>DROP DATABASE</command> cannot be undone. Use it with care!

<title>Notes</title>
<para>
<command>DROP DATABASE</> cannot be executed inside a transaction
block.
</para>
<para>
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"> instead,
which is a wrapper around this command.
</para>
</refsect1>
<refsect1>
<title>Compatibility</title>
<para>
There is no <command>DROP DATABASE</command> statement in the SQL standard.
