H2 Database Engine 1.1.106 (Default branch)
ImageH2 is an SQL database engine written in Java thatimplements the JDBC API. Embedded, server, andclustering modes are available. A browser basedconsole application is included. The database hasstrong security features. Disk based and in-memory databases and tables are supported.License: Eclipse Public LicenseChanges:
Built-in data types can now only be changed if notables exist. DatabaseMetaData.getPrimaryKeys: Thecolumn PK_NAME now contains the constraint nameinstead of the index name. The license was changeda bit: previously, the license was modified to say"Swiss law". This is changed back to the original"US law". Statement.setQueryTimeout did not workcorrectly for some statements. Nested IN(..)constructs did not always work.Image

NAME

       createdb - create a new PostgreSQL database

SYNOPSIS

       createdb [ options... ] [ dbname ] [ description ]

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 -O option, if the executing user has appropriate privileges.

       createdb is a shell script wrapper around the SQL command CREATE DATABASE [create_database(7)]  via  the  PostgreSQL  interactive  terminal
       psql(1).  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  avail-
       able to psql and the libpq front-end library will apply.

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 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.

       -D location

       --location location
	      Specifies the alternative location for the database. See also initlocation(1).

       -e

       --echo Echo the queries that createdb generates and sends to the server.

       -E encoding

       --encoding encoding
	      Specifies the character encoding scheme to be used in this database.

       -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 [create_database(7)]; 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 host begins with a slash, it is used as the directory for
	      the Unix domain socket.

       -p port

       --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 username
	      User name to connect as

       -W

       --password
	      Force password prompt.

DIAGNOSTICS

       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 [create_database(7)] and psql(1) for pos-
       sibilities.

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.

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 query:

       $ createdb -p 5000 -h eden -E LATIN1 -e demo
       CREATE DATABASE "demo" WITH ENCODING = 'LATIN1'
       CREATE DATABASE
