-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
Force password prompt.
Echo the queries that createdb generates and sends to the server.
Do not display a response.
-D, --location datadir
Specifies the alternative location for the database. See also initlocation(1).
-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.
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.
This optionally specifies a comment to be associated with the newly created database.
The options -h, -p, -U, -W, and -e are passed on literally to psql(1). The options -D, -T, and -E are converted into options for the underlying SQL command CREATE DATABASE [__create_database__(l)?; see there for more information about them.
The 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.
createdb creates a new PostgreSQL database. The user who executes this command becomes the database owner.
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 query:
