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 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 PostgreSQL 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 a PostgreSQL extension.
