SYNOPSIS

10       CREATE TABLESPACE tablespacename [ OWNER username ] LOCATION 'directory'
11
12

DESCRIPTION

14       CREATE   TABLESPACE   registers  a  new  cluster-wide  tablespace.  The
15       tablespace name  must  be  distinct  from  the  name  of  any  existing
16       tablespace in the database cluster.
17
18       A tablespace allows superusers to define an alternative location on the
19       file system where the data files containing database objects  (such  as
20       tables and indexes) can reside.
21
22       A  user  with  appropriate privileges can pass tablespacename to CREATE
23       DATABASE, CREATE TABLE, CREATE INDEX or ADD CONSTRAINT to have the data
24       files for these objects stored within the specified tablespace.
25

PARAMETERS

27       tablespacename
28              The  name  of  a tablespace to be created. The name cannot begin
29              with pg_, as such names are reserved for system tablespaces.
30
31       username
32              The name of the user who will own the  tablespace.  If  omitted,
33              defaults  to the user executing the command. Only superusers can
34              create tablespaces, but they can assign ownership of tablespaces
35              to non-superusers.
36
37       directory
38              The  directory  that will be used for the tablespace. The direc‐
39              tory must be empty and must be owned by  the  PostgreSQL  system
40              user. The directory must be specified by an absolute path name.
41

NOTES

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

45       CREATE TABLESPACE cannot be executed inside a transaction block.
