CREATE TABLESPACE(7)                                      SQL Commands                                      CREATE TABLESPACE(7)



NAME
       CREATE TABLESPACE - define a new tablespace


SYNOPSIS
       CREATE TABLESPACE tablespacename [ OWNER username ] LOCATION 'directory'


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 data-
       base objects (such as tables and indexes) can reside.

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

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

       username
              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 must be empty and must be  owned  by  the  Post-
              greSQL system user. The directory must be specified by an absolute path name.

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.
