NAME
       ALTER_TABLESPACE - change the definition of a tablespace

SYNOPSIS
       ALTER TABLESPACE name RENAME TO new_name
       ALTER TABLESPACE name OWNER TO new_owner
       ALTER TABLESPACE name SET ( tablespace_option = value [, ... ] )
       ALTER TABLESPACE name RESET ( tablespace_option [, ... ] )

DESCRIPTION
       ALTER TABLESPACE changes the definition of a tablespace.

       You must own the tablespace to use ALTER TABLESPACE. To alter the
       owner, you must also be a direct or indirect member of 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_parameter
	   A tablespace parameter to be set or reset. Currently, the only
	   available parameters are seq_page_cost and random_page_cost.
	   Setting either value for a particular tablespace will override the
	   planner's usual estimate of the cost of reading pages from tables
	   in that tablespace, as established by the configuration parameters
	   of the same name (see seq_page_cost, random_page_cost). 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;

COMPATIBILITY
       There is no ALTER TABLESPACE statement in the SQL standard.
