Notes
</title>
<para>
This command cannot be executed while connected to the target
database. Thus, it might be more convenient to use the shell
script <xref linkend="app-dropdb" endterm="app-dropdb-title">,
which is a wrapper around this command, instead.
</para>
<para>
Refer to
<xref linkend="sql-createdatabase" endterm="sql-createdatabase-title">
for information on how to create a database.
