createdbNamecreatedb -- create a new EnterpriseDB database Synopsiscreatedb [option...] [dbname] [description] Description
createdb creates a new EnterpriseDB
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.
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 EnterpriseDB 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.
- -E encoding
--encoding encoding Specifies the character encoding scheme to be used in this
database. The character sets supported by the
EnterpriseDB server are described in
Section 34.2.1.
- -O owner
--owner owner Specifies the database user who will own the new database.
- -q
--quiet Do not display a response.
- -T template
--template template Specifies the template database from which to build this database.
The options -D, -E,
-O, and
-T correspond to options of the underlying
SQL command CREATE DATABASE; 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
--password Force password prompt.
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.
Diagnostics In case of difficulty, see CREATE DATABASE and edb-psql 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
CREATE 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 command:
$ createdb -p 5000 -h eden -E LATIN1 -e demo
CREATE DATABASE "demo" WITH ENCODING = 'LATIN1'
