CREATE_DATABASE (l)

Creates a new database

SYNOPSIS

    CREATE DATABASE name [ WITH LOCATION = 'dbpath' ]
    

    name

      The name of a database to create.

    dbpath

      An alternate location for the new database. See below for caveats.

    CREATEDB

      Message returned if the command completes successfully.

    WARN: createdb: database "name" already exists.

      This occurs if database specified already exists.

    ERROR: Unable to create database directory directory

      There was a problem with creating the required directory; this operation will need permissions for the postgres user on the specified location.

DESCRIPTION

    CREATE DATABASE creates a new Postgres database. The creator becomes the administrator of the new database.

    An alternate location can be specified as either an environment variable known to the backend server (e.g. 'PGDATA2') or, if the server is built to allow it, as an absolute path name (e.g. '/usr/local/pgsql/data'). In either case, the location must be pre-configured by initlocation.

    CREATE DATABASE is a Postgres language extension.

    Use DROP DATABASE to remove a database.

    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.

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
    Creating Postgres database system directory /home/olly/private_db/base
    

    $ psql olly Welcome to the POSTGRESQL interactive sql monitor: Please read the file COPYRIGHT for copyright terms of POSTGRESQL

    type \\? for help on slash commands type \\q to quit type \\g or terminate with semicolon to execute query You are currently connected to the database: template1

    olly=> create database elsewhere with location = '/home/olly/private_db'; CREATEDB

COMPATIBILITY

    There is no CREATE DATABASE statement in SQL92. The equivalent command in standard SQL is CREATE SCHEMA.
