NAME

6       ALTER_TABLESPACE - change the definition of a tablespace
7

SYNOPSIS

9       ALTER TABLESPACE name RENAME TO new_name
10       ALTER TABLESPACE name OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }
11       ALTER TABLESPACE name SET ( tablespace_option = value [, ... ] )
12       ALTER TABLESPACE name RESET ( tablespace_option [, ... ] )
13

DESCRIPTION

15       ALTER TABLESPACE can be used to change the definition of a tablespace.
16
17       You must own the tablespace to change the definition of a tablespace.
18       To alter the owner, you must also be able to SET ROLE to the new owning
19       role. (Note that superusers have these privileges automatically.)

PARAMETERS

22       name
23           The name of an existing tablespace.
24
25       new_name
26           The new name of the tablespace. The new name cannot begin with pg_,
27           as such names are reserved for system tablespaces.
28
29       new_owner
30           The new owner of the tablespace.
31
32       tablespace_option
33           A tablespace parameter to be set or reset. Currently, the only
34           available parameters are seq_page_cost, random_page_cost,
35           effective_io_concurrency and maintenance_io_concurrency. Setting
36           these values for a particular tablespace will override the
37           planner's usual estimate of the cost of reading pages from tables
38           in that tablespace, and the executor's prefetching behavior, as
39           established by the configuration parameters of the same name (see
40           seq_page_cost, random_page_cost, effective_io_concurrency,
41           maintenance_io_concurrency). This may be useful if one tablespace
42           is located on a disk which is faster or slower than the remainder
43           of the I/O subsystem.

EXAMPLES

46       Rename tablespace index_space to fast_raid:
47
48           ALTER TABLESPACE index_space RENAME TO fast_raid;
49
50       Change the owner of tablespace index_space:
51
52           ALTER TABLESPACE index_space OWNER TO mary;
53

COMPATIBILITY

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