ALTER TABLESPACE(7)     PostgreSQL 9.6.6 Documentation     ALTER TABLESPACE(7)




NAME

       ALTER_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.
