CREATEDB(1)             PostgreSQL 9.4.5 Documentation             CREATEDB(1)



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';
