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  con-
       taining database 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 CONSTRAINT 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 com-
              mand. Only superusers can create tablespaces, but they can assign ownership of tablespaces to  non-supe-
              rusers.

       directory
              The directory that will be used for the tablespace. The directory must be empty and must be owned by the
              PostgreSQL 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.
