NAME
createdb - create a new PostgreSQL database
SYNOPSIS
createdb [ option... ] [ dbname ] [ description ]
DESCRIPTION
createdb creates a new PostgreSQL database.
Normally, the database user who executes this command
becomes the owner of the new database. However a different
owner can be specified via the -O option, if the executing
user has appropriate privileges.
createdb is a wrapper around the SQL command CREATE DATABASE
[create_database(5)]. There is no effective difference
between creating databases via this utility and via other
methods for accessing the server.
OPTIONS
createdb accepts the following command-line arguments:
dbname
Specifies the name of the database to be created. The
name must be unique among all PostgreSQL databases in
this cluster. The default is to create a database with
the same name as the current system user.
description
Specifies a comment to be associated with the newly
created database.
-D tablespace
--tablespace tablespace
Specifies the default tablespace for the database.
-e
--echo
Echo the commands that createdb generates and sends to
the server.
-E encoding
--encoding encoding
Specifies the character encoding scheme to be used in
this database. The character sets supported by the
PostgreSQL server are described in in the documenta-
tion.

-O owner
--owner owner
Specifies the database user who will own the new data-
base.
-q
--quiet
Do not display a response.
-T template
--template template
Specifies the template database from which to build
this database.
The options -D, -E, -O, and -T correspond to options of the
underlying SQL command CREATE DATABASE [create_database(5)];
see there for more information about them.
createdb also accepts the following command-line arguments
for connection parameters:
-h host
--host host
Specifies the host name of the machine on which the
server is running. If the value begins with a slash, it
is used as the directory for the Unix domain socket.
-p port
--port port
Specifies the TCP port or the local Unix domain socket
file extension on which the server is listening for
connections.
-U username
--username username
User name to connect as
-W
--password
Force password prompt.
ENVIRONMENT
PGDATABASE
If set, the name of the database to create, unless
overridden on the command line.

PGHOST
PGPORT
PGUSER
Default connection parameters. PGUSER also determines
the name of the database to create, if it is not speci-
fied on the command line or by PGDATABASE.
This utility, like most other PostgreSQL utilities, also
uses the environment variables supported by libpq (see in
the documentation).
DIAGNOSTICS
In case of difficulty, see CREATE DATABASE
[create_database(5)] and psql(1) for discussions of poten-
tial problems and error messages. The database server must
be running at the targeted host. Also, any default connec-
tion settings and environment variables used by the libpq
front-end library will apply.
EXAMPLES
To create the database demo using the default database
server:
$ createdb demo
CREATE DATABASE
The response is the same as you would have gotten from run-
ning the CREATE DATABASE SQL command.
To create the database demo using the server on host eden,
port 5000, using the LATIN1 encoding scheme with a look at
the underlying command:
$ createdb -p 5000 -h eden -E LATIN1 -e demo
CREATE DATABASE "demo" WITH ENCODING = 'LATIN1'
