CREATEDB(1) PostgreSQL Client Applications CREATEDB(1)NAMEcreatedb - create a new PostgreSQL database
SYNOPSIScreatedb [ option... ] [ dbname ] [ description ]
DESCRIPTIONcreatedb 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 [cre‐
ate_database(7)]. There is no effective difference between creating
databases via this utility and via other methods for accessing the
OPTIONScreatedb 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 cur‐
rent system user.
Specifies a comment to be associated with the newly created
Specifies the default tablespace for the database.
--echo Echo the commands that createdb generates and sends to the
Specifies the character encoding scheme to be used in this data‐
base. The character sets supported by the PostgreSQL server are
described in the documentation.
Specifies the database user who will own the new database.
Do not display a response.
Specifies the template database from which to build this data‐
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 connec‐
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.
Specifies the TCP port or the local Unix domain socket file
extension on which the server is listening for connections.
User name to connect as
Force password prompt.
If set, the name of the database to create, unless overridden on
the command line.
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.
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.
To create the database demo using the default database server:
$ createdb demo
The response is the same as you would have gotten from running the CRE‐
ATE 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'
