ALTER TABLESPACE

ALTER TABLESPACE - change the definition of a tablespace

Synopsis

ALTER TABLESPACE name RENAME TO new_name
ALTER TABLESPACE name OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }
ALTER TABLESPACE name SET ( tablespace_option = value [, ... ] )
ALTER TABLESPACE name RESET ( tablespace_option [, ... ] )

Description

ALTER TABLESPACE can be used to change the definition of a tablespace.

You must own the tablespace to change the definition of a tablespace. To alter the owner, you must also be able to SET ROLE to the new owning role. (Note that superusers have these privileges automatically.)

Parameters

name: The name of an existing tablespace.
new_name: The new name of the tablespace. The new name cannot begin with pg_ , as such names are reserved for system tablespaces.
new_owner: The new owner of the tablespace.
tablespace_option: A tablespace parameter to be set or reset. Currently, the only available parameters are seq_page_cost , random_page_cost , effective_io_concurrency and maintenance_io_concurrency . Setting these values for a particular tablespace will override the planner's usual estimate of the cost of reading pages from tables in that tablespace, and how many concurrent I/Os are issued, as established by the configuration parameters of the same name (see seq_page_cost , random_page_cost , effective_io_concurrency , maintenance_io_concurrency ). This may be useful if one tablespace is located on a disk which is faster or slower than the remainder of the I/O subsystem.

Examples

Rename tablespace index_space to fast_raid :

ALTER TABLESPACE index_space RENAME TO fast_raid;

Change the owner of tablespace index_space :

ALTER TABLESPACE index_space OWNER TO mary;
