.SH "SYNOPSIS"
.sp
.nf
CREATE TABLESPACE \fItablespace_name\fR [ OWNER \fIuser_name\fR ] LOCATION \*(Aq\fIdirectory\fR\*(Aq
.fi
.SH "DESCRIPTION"
.PP
\fBCREATE TABLESPACE\fR
registers a new cluster\-wide tablespace\&. The tablespace name must be distinct from the name of any existing tablespace in the database cluster\&.
.PP
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\&.
.PP
A user with appropriate privileges can pass
\fItablespace_name\fR
to
\fBCREATE DATABASE\fR,
\fBCREATE TABLE\fR,
\fBCREATE INDEX\fR
or
\fBADD CONSTRAINT\fR
to have the data files for these objects stored within the specified tablespace\&.
.SH "PARAMETERS"
.PP
\fItablespace_name\fR
.RS 4
The name of a tablespace to be created\&. The name cannot begin with
pg_, as such names are reserved for system tablespaces\&.
.RE
.PP
\fIuser_name\fR
.RS 4
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\&.
.RE
.PP
\fIdirectory\fR
.RS 4
The directory that will be used for the tablespace\&. The directory should be empty and must be owned by the
PostgreSQL
system user\&. The directory must be specified by an absolute path name\&.
.RE
.SH "NOTES"
.PP
Tablespaces are only supported on systems that support symbolic links\&.
.PP
\fBCREATE TABLESPACE\fR
cannot be executed inside a transaction block\&.
.SH "EXAMPLES"
.PP
