CREATE DATABASE(7)			   SQL Commands 		       CREATE DATABASE(7)

NAME
       CREATE DATABASE - create a new database

SYNOPSIS
       CREATE DATABASE name
	   [ [ WITH ] [ OWNER [=] dbowner ]
		  [ LOCATION [=] 'dbpath' ]
		  [ TEMPLATE [=] template ]
		  [ ENCODING [=] encoding ] ]

   INPUTS
       name   The name of a database to create.

       dbowner
	      Name  of	the  database  user  who will own the new database, or DEFAULT to use the
	      default (namely, the user executing the command).

       dbpath An alternate file-system location in which to store the new database, specified  as
	      a string literal; or DEFAULT to use the default location.

       template
	      Name  of	template  from	which  to  create the new database, or DEFAULT to use the
	      default template (template1).

       encoding
	      Multibyte encoding method to use in the new database. Specify a string literal name
	      (e.g.,  'SQL_ASCII'),  or an integer encoding number, or DEFAULT to use the default
	      encoding.

   OUTPUTS
       CREATE DATABASE
	      Message returned if the command completes successfully.

       ERROR: user 'username' is not allowed to create/drop databases
	      You must have the special CREATEDB privilege to create databases.  See CREATE  USER
	      [create_user(7)].

       ERROR: createdb: database "name" already exists
	      This occurs if a database with the name specified already exists.

       ERROR: database path may not contain single quotes
	      The database location dbpath cannot contain single quotes. This is required so that
	      the shell commands that create the database directory can execute safely.

       ERROR: CREATE DATABASE: may not be called in a transaction block
	      If you have an explicit transaction block in progress you cannot call CREATE  DATA-
	      BASE. You must finish the transaction first.

       ERROR: Unable to create database directory 'path'.

       ERROR: Could not initialize database directory.
	      These  are most likely related to insufficient permissions on the data directory, a
	      full disk, or other file system problems. The user under which the database  server
	      is running must have access to the location.

DESCRIPTION
       CREATE DATABASE creates a new PostgreSQL database.

       Normally,  the creator becomes the owner of the new database.  Superusers can create data-
       bases owned by other users using the OWNER clause. They can even create databases owned by
       users  with  no special privileges. Non-superusers with CREATEDB privilege can only create
       databases owned by themselves.

       An alternate location can be specified in order to, for example, store the database  on	a
       different  disk.  The path must have been prepared with the initlocation [initlocation(1)]
       command.

       If the path name does not contain a slash, it is interpreted as	an  environment  variable
       name,  which  must be known to the server process. This way the database administrator can
       exercise control over locations in which databases can be created.   (A	customary  choice
       is,  e.g.,  PGDATA2.)   If  the	server is compiled with ALLOW_ABSOLUTE_DBPATHS (not so by
       default),   absolute   path   names,   as   identified	by   a	 leading   slash   (e.g.,
       /usr/local/pgsql/data), are allowed as well.

       By  default, the new database will be created by cloning the standard system database tem-
       plate1. A different template can be specified by writing TEMPLATE = name.  In  particular,
       by  writing  TEMPLATE  =  template0,  you can create a virgin database containing only the
       standard objects predefined by your version of PostgreSQL. This is useful if you  wish  to
       avoid copying any installation-local objects that may have been added to template1.

       The  optional encoding parameter allows selection of the database encoding, if your server
       was compiled with multibyte encoding support. When  not	specified,  it	defaults  to  the
       encoding used by the selected template database.

       Optional parameters can be written in any order, not only the order illustrated above.

   NOTES
       CREATE DATABASE is a PostgreSQL language extension.

       Use DROP DATABASE [drop_database(7)] to remove a database.

       The program createdb [createdb(1)] is a shell script wrapper around this command, provided
       for convenience.

       There are security and data integrity issues involved with using alternate database  loca-
       tions  specified  with  absolute  path  names, and by default only an environment variable
       known to the backend may be specified for an alternate location.  See the  Administrator's
       Guide for more information.

       Although  it is possible to copy a database other than template1 by specifying its name as
       the template, this is not (yet) intended as a general-purpose COPY DATABASE facility.   We
       recommend  that	databases used as templates be treated as read-only.  See the Administra-
       tor's Guide for more information.

USAGE
       To create a new database:

       olly=> create database lusiadas;

       To create a new database in an alternate area ~/private_db:

       $ mkdir private_db
       $ initlocation ~/private_db
	   The location will be initialized with username "olly".
       This user will own all the files and must also own the server process.
       Creating directory /home/olly/private_db
       Creating directory /home/olly/private_db/base

       initlocation is complete.

       $ psql olly
       Welcome to psql, the PostgreSQL interactive terminal.

       Type:  \copyright for distribution terms
	      \h for help with SQL commands
	      \? for help on internal slash commands
	      \g or terminate with semicolon to execute query
	      \q to quit

       olly=> CREATE DATABASE elsewhere WITH LOCATION = '/home/olly/private_db';
       CREATE DATABASE

COMPATIBILITY
   SQL92
       There is no CREATE DATABASE statement in SQL92.	Databases  are	equivalent  to	catalogs,
       whose creation is implementation-defined.
