NAME
       createdb - create a new PostgreSQL database

SYNOPSIS
       createdb [connection-option...] [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. (This name is
	   processed as a double-quoted identifier.)

       -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 Section 22.3.1, "Supported Character Sets", in the
	   documentation.

       -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.

       -O owner, --owner=owner
	   Specifies the database user who will own the new database. (This
	   name is processed as a double-quoted identifier.)

       -T template, --template=template
	   Specifies the template database from which to build this database.
	   (This name is processed as a double-quoted identifier.)

       -V, --version
	   Print the createdb version and exit.

       -?, --help
	   Show help about createdb command line arguments, and exit.

       The options -D, -l, -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, --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.

       --maintenance-db=dbname
	   Specifies the name of the database to connect to when creating the
	   new database. If not specified, the postgres database will be used;
	   if that does not exist (or if it is the name of the new database
	   being created), template1 will be used.

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 Section 31.14,
       "Environment Variables", in the documentation).

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

       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';
