ALTER TABLESPACE — change the definition of a tablespace

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.)
nameThe 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_ownerThe 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.
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;
There is no ALTER TABLESPACE statement in
the SQL standard.
