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 data-
       bases 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 [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 authentica-
	      tion.  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 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  com-
       mand:

       $ createdb -p 5000 -h eden -E LATIN1 -e demo
       CREATE DATABASE demo ENCODING 'LATIN1';
