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 wrapper around the
SQL command . Thus, there is nothing
special about creating databases via this or other methods. This
means that a database server must be running at the targeted
port. Also, any default settings and environment variables used by
the libpq front-end library will apply.
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 installation.
The default is to create a database with the same name as the
current system user.
description
This optionally specifies a comment to be associated with the newly created
database.
Specifies the alternative location for the database. See also .
Echo the queries that createdb generates
and sends to the server.
Specifies the character encoding scheme to be used in this database.
Specifies the database user who will own the new database.
Do not display a response.
Specifies the template database from which to build this database.
The options , ,
, and
correspond to options of the underlying
SQL command ; see there for more information
about them.
createdb also accepts the following
command-line arguments for connection parameters:
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.
Specifies the Internet TCP/IP 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.
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.
See
for possibilities.
EnvironmentPGDATABASE
If set, the name of the database to create, unless overridden on
the command line.
PGHOSTPGPORTPGUSER
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.
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
