tablespace(s) in which to store temp tables and temporary files. This is a list to allow spreading the load across multiple tablespaces (a random list element is chosen each time a temp object is to be created). Temp files are not stored in per-database pgsql_tmp/ directories anymore, but per-tablespace directories. Jaime Casanova and Albert Cervera, with review by Bernd Helmle and Tom Lane.

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</> might fail due to temporary files residing in the
|
|
tablespace.
