createdb [options] [dbname] [description]
Specifies the name of the database to be created. The name must be unique among all PostgreSQL databases in this installation. The default is to create a database with the same name as the current system user.
This optionally specifies a comment to be associated with the newly created database.
Specifies the alternative location for the database.
Echo the queries that createdb generates and sends to the backend.
Specifies the character encoding scheme to be used in this database.
Specifies the hostname of the machine on which the postmaster is running. If host begins with a slash, it is used as the directory for the UNIX domain socket.
Specifies the Internet TCP/IP port or the local UNIX domain socket file extension on which the postmaster is listening for connections.
Do not display a response.
Specifies the template database from which to build this database.
Username to connect as.

The database was successfully created.
The database failed to be created.
The comment/description for the database could not be created. The database itself will have been created already. You can use the SQL command COMMENT ON DATABASE to create the comment.
createdb creates a new PostgreSQL database. The user who executes this command becomes the database owner.
createdb is a shell script wrapper around the SQL command CREATE DATABASE via the PostgreSQL interactive terminal psql. There is nothing special about creating databases via this or other methods. The psql program must be found by the script and a database server must be running at the targeted port. Any default settings and environment variables available to psql and the libpq front-end library will apply.
To create the database demo using the default database server:
$ createdb demo CREATE DATABASE |
To create the database demo using the postmaster on host eden, port 5000, using the LATIN1 encoding scheme with a look at the underlying query:
$ createdb -p 5000 -h eden -E LATIN1 -e demo CREATE DATABASE "demo" WITH ENCODING = 'LATIN1' CREATE DATABASE |
