    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(7)]. 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 the documentation.
    -O owner
    --owner owner
    Specifies the database user who will own the new database.
    -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(7)]; 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 specified on the command line or by PGDATABASE.
     

    DIAGNOSTICS

    In case of difficulty, see CREATE DATABASE [create_database(7)] and psql(1) for discussions of potential problems and error messages. The database server must be running at the targeted host. Also, any default connection 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 running 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'
    CREATE DATABASE
