CREATE TABLESPACENameCREATE TABLESPACE -- define a new tablespace SynopsisCREATE 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 database objects
(such as tables and indexes) may 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 command. Only superusers
may 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
EnterpriseDB system user. The directory must be
specified by an absolute path name.
Notes Tablespaces are only supported on systems that support symbolic links.
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 an EnterpriseDB
extension.
