CREATE TABLESPACE(7)	PostgreSQL 9.6.3 Documentation	  CREATE TABLESPACE(7)

NAME
       CREATE_TABLESPACE - define a new	tablespace

SYNOPSIS
       CREATE TABLESPACE tablespace_name
	   [ OWNER { new_owner | CURRENT_USER |	SESSION_USER } ]
	   LOCATION 'directory'
	   [ WITH ( tablespace_option =	value [, ... ] ) ]

DESCRIPTION
       CREATE TABLESPACE registers a new cluster-wide tablespace. The
       tablespace name must be distinct	from the name of any existing
       tablespace in the database cluster.

       A tablespace allows superusers to define	an alternative location	on the
       file system where the data files	containing database objects (such as
       tables and indexes) can reside.

       A user with appropriate privileges can pass tablespace_name to CREATE
       DATABASE, CREATE	TABLE, CREATE INDEX or ADD CONSTRAINT to have the data
       files for these objects stored within the specified tablespace.

	   Warning
	   A tablespace	cannot be used independently of	the cluster in which
	   it is defined; see Section 22.6, "Tablespaces", in the
	   documentation.

PARAMETERS
       tablespace_name
	   The name of a tablespace to be created. The name cannot begin with
	   pg_,	as such	names are reserved for system tablespaces.

       user_name
	   The name of the user	who will own the tablespace. If	omitted,
	   defaults to the user	executing the command. Only superusers can
	   create tablespaces, but they	can assign ownership of	tablespaces to
	   non-superusers.

       directory
	   The directory that will be used for the tablespace. The directory
	   should be empty and must be owned by	the PostgreSQL system user.
	   The directory must be specified by an absolute path name.

       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.

NOTES
       Tablespaces are only supported on systems that support symbolic links.

       CREATE TABLESPACE cannot	be executed inside a transaction block.

EXAMPLES
       Create a	tablespace dbspace at /data/dbs:

	   CREATE TABLESPACE dbspace LOCATION '/data/dbs';

       Create a	tablespace indexspace at /data/indexes owned by	user
       genevieve:

	   CREATE TABLESPACE indexspace	OWNER genevieve	LOCATION '/data/indexes';

COMPATIBILITY
       CREATE TABLESPACE is a PostgreSQL extension.
