createdb1Applicationcreatedbcreate a new PostgreSQL databasecreatedboptionsdbnamedescription
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
option, if the executing user has appropriate privileges.
createdb is a shell script wrapper around the
SQL command
via
the PostgreSQL interactive terminal
. Thus, there is nothing
special about creating databases via this or other methods. This means
that the psql program must be found by the script and that
a database server must be running at the targeted port. Also, any default
settings and environment variables available to psql
and the libpq front-end library will apply.
Options-h, --host host
Specifies the host name of the machine on which the
server is running. If host begins with a slash, it is used
as the directory for the Unix domain socket.
-p, --port port
Specifies the Internet TCP/IP port or the local Unix domain socket file
extension on which the server is listening for connections.
-U, --username username
User name to connect as
-W, --password
Force password prompt.
-e, --echo
Echo the queries that createdb generates
and sends to the server.
-q, --quiet
Do not display a response.
-O, --owner owner
Specifies the database user who will own the new database.
-D, --location datadir
Specifies the alternative location for the database. See also .
-T, --template template
Specifies the template database from which to build this database.
-E, --encoding encoding
Specifies the character encoding scheme to be used in this database.
dbname
Specifies the name of the database to be created. The name must be
unique among all PostgreSQL databases in this installation.
The default is to create a database with the same name as the
current system user.

DiagnosticsCREATE DATABASEThe database was successfully created.createdb: Database creation failed.(Says it all.)createdb: Comment creation failed. (Database was created.)
The comment/description for the database could not be created.
The database itself will have been created already. You can use the
SQL command COMMENT ON DATABASE to
create the comment later on.
If there is an error condition, the backend error message will be displayed.

determines the name of the database to create, if it is not
specified in the command line.
Examples
To create the database demo using the default
database server:
$ createdb demoCREATE DATABASE
The response is the same as you would have gotten from running the
CREATE 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 query:
$ createdb -p 5000 -h eden -E LATIN1 -e demoCREATE DATABASE "demo" WITH ENCODING = 'LATIN1'CREATE DATABASESee Also
