ALTER TABLESPACE(7) PostgreSQL 10.1 Documentation ALTER TABLESPACE(7)NAMEALTER_TABLESPACE - change the definition of a tablespace
SYNOPSIS
ALTER TABLESPACE name RENAME TO new_name
ALTER TABLESPACE name OWNER TO { new_owner | 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 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_option
A tablespace parameter to be set or reset. Currently, the only
available parameters are seq_page_cost, random_page_cost and
effective_io_concurrency. 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, effective_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;
COMPATIBILITY
There is no ALTER TABLESPACE statement in the SQL standard.
