DROP TABLESPACE — remove a tablespace
DROP TABLESPACE [ IF EXISTS ] name
DROP TABLESPACE removes a tablespace from the system.
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 temp_tablespaces setting of any active session, the
DROP might fail due to temporary files residing in the
tablespace.
IF EXISTSDo not throw an error if the tablespace does not exist. A notice is issued in this case.
nameThe name of a tablespace.
DROP TABLESPACE cannot be executed inside a transaction block.
To remove tablespace mystuff from the system:
DROP TABLESPACE mystuff;
DROP TABLESPACE is a PostgreSQL
extension.
