CREATE
NAME
CREATE DATABASE - create a new database
SYNOPSIS
CREATE DATABASE name
[ [ WITH ] [ OWNER [=] dbowner ]
[ TEMPLATE [=] template ]
[ ENCODING [=] encoding ]
[ TABLESPACE [=] tablespace ] ]
DESCRIPTION
CREATE DATABASE creates a new PostgreSQL database.
To create a database, you must be a superuser or have the special CREATEDB
privilege. See CREATE USER [create_user(5)].
Normally, the creator becomes the owner of the new database. Superusers
can create databases owned by other users using the OWNER clause. They can
even create databases owned by users with no special privileges. Non-
superusers with CREATEDB privilege can only create databases owned by
themselves.
By default, the new database will be created by cloning the standard system
database template1. A different template can be specified by writing
TEMPLATE name. In particular, by writing TEMPLATE template0, you can create
a virgin database containing only the standard objects predefined by your
version of PostgreSQL. This is useful if you wish to avoid copying any
installation-local objects that may have been added to template1.
PARAMETERS
name The name of a database to create.
dbowner
The name of the database user who will own the new database, or
DEFAULT to use the default (namely, the user executing the command).
template
The name of the template from which to create the new database, or
DEFAULT to use the default template (template1).
encoding
Character set encoding to use in the new database. Specify a string
constant (e.g., 'SQL_ASCII'), or an integer encoding number, or
DEFAULT to use the default encoding. The character sets supported by
the PostgreSQL server are described in the documentation.
tablespace
The name of the tablespace that will be associated with the new
database, or DEFAULT to use the template database's tablespace. This
tablespace will be the default tablespace used for objects created in
this database. See CREATE TABLESPACE [create_tablespace(5)] for more
information.
Optional parameters can be written in any order, not only the order
illustrated above.
NOTES
CREATE DATABASE cannot be executed inside a transaction block.
Errors along the line of ``could not initialize database directory'' are
most likely related to insufficient permissions on the data directory, a
full disk, or other file system problems.
Use DROP DATABASE [drop_database(5)] to remove a database.
The program createdb [createdb(1)] is a wrapper program around this
command, provided for convenience.
Although it is possible to copy a database other than template1 by
specifying its name as the template, this is not (yet) intended as a
general-purpose ``COPY DATABASE'' facility. We recommend that databases
used as templates be treated as read-only. See the documentation for more
information.
EXAMPLES
To create a new database:
CREATE DATABASE lusiadas;
To create a database sales owned by user salesapp with a default tablespace
of salesspace:
CREATE DATABASE sales OWNER salesapp TABLESPACE salesspace;
To create a database music which supports the ISO-8859-1 character set:
CREATE DATABASE music ENCODING 'LATIN1';
COMPATIBILITY
There is no CREATE DATABASE statement in the SQL standard. Databases are
equivalent to catalogs, whose creation is implementation-defined.
