1.61 CREATE TABLESPACE
Name
CREATE TABLESPACE -- define a new tablespace
Synopsis
CREATE TABLESPACE tablespace_name [ OWNER user_name ] 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 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.
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 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.
