Specifies the hostname of the machine on which the
postmaster
is running.
-p, --port port
Specifies the Internet TCP/IP port or local Unix domain socket file
extension on which the postmaster
is listening for connections.
-U, --username username
Username to connect as.
-W, --password
Force password prompt.
-e, --echo

and sends to the backend.
-q, --quiet
Do not display a response.
-D, --location datadir
Specifies the alternate database location for this database installation.
This is the location of the installation system tables, not the location
of this specific database, which may be different.
-E, --encoding encoding
Specifies the character encoding scheme to be used with this database.
dbname
Specifies the name of the database to be created. The name must be
unique among all Postgres 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.
The options -h, -p, -U,
-W, and -e are passed on literally to
psql.
Outputs
CREATE DATABASE
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.
If there is an error condition, the backend error message will be displayed.
See CREATE DATABASE
and psql for possibilities.
Description
createdb creates a new Postgres
database. The user who executes this command becomes the database owner.
createdb is a shell script wrapper around the
SQL command
CREATE DATABASE via
the Postgres interactive terminal
psql. Thus, there is nothing
special about creating databases via this or other methods. This means
that the psql must be found by the script and that
a database server is running at the targeted host. Also, any default
settings and environment variables available to psql
and the libpq front-end library do apply.
Usage
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 DATABASESQL command.
To create the database demo
using the postmaster 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 demo
CREATE DATABASE "demo" WITH ENCODING = 'LATIN1'
CREATE DATABASE
