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 differ-
       ent 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  dif-
       ference 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.

       -l locale

       --locale locale
              Specifies the locale to be used in this database. This is equivalent to specifying both --lc-collate and
              --lc-ctype.

       --lc-collate locale
              Specifies the LC_COLLATE setting to be used in this database.

       --lc-ctype locale
              Specifies the LC_CTYPE setting to be used in this database.

       -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 documentation.

       -O owner

       --owner owner
              Specifies the database user who will own the new database.

       -T template

       --template template
              Specifies the template database from which to build this database.


       The options -D, -E, -l, -O, and -T correspond to options of the underlying SQL command  CREATE  DATABASE  [cre-
       ate_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

       --no-password
              Never  issue  a  password  prompt.  If the server requires password authentication and a password is not
              available by other means such as a .pgpass file, the connection attempt will fail. This  option  can  be
              useful in batch jobs and scripts where no user is present to enter a password.

       -W

       --password
              Force createdb to prompt for a password before connecting to a database.

              This  option  is  never essential, since createdb will automatically prompt for a password if the server
              demands password authentication.  However, createdb will waste a connection attempt finding out that the
              server wants a password.  In some cases it is worth typing -W to avoid the extra connection attempt.


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.

       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(7)] and psql(1) for discussions of potential prob-
       lems 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


       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 ENCODING 'LATIN1';
