<para>
|
|
<command>DROP DATABASE</command> removes the catalog entries for an existing
|

database and deletes the directory containing the data.

It can only be executed by the database owner (usually the user that created
|
|
it).

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

<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.
