<title>Description</title>
<para>
<command>DROP TABLESPACE</command> removes a tablespace from the system.
</para>
<para>
A tablespace can only be dropped by its owner or a superuser.
The tablespace must be empty of all database objects before it can be
dropped. It is possible that objects in other databases might still reside
in the tablespace even if no objects in the current database are using
the tablespace. Also, if the tablespace is listed in the <xref
linkend="guc-temp-tablespaces"/> setting of any active session, the
<command>DROP</command> might fail due to temporary files residing in the
tablespace.
