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 num-
	      ber, 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 DATABASE. 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 databases 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 template1. 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 locations 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  Administrator'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.
