       CREATE DATABASE - create a new database

	   [ [ WITH ] [ OWNER [=] dbowner ]
		  [ TEMPLATE [=] template ]
		  [ ENCODING [=] encoding ]
		  [ LC_COLLATE [=] lc_collate ]
		  [ LC_CTYPE [=] lc_ctype ]
		  [ TABLESPACE [=] tablespace ]
		  [ CONNECTION LIMIT [=] connlimit ] ]

       CREATE DATABASE creates a new PostgreSQL database.

       To  create a database, you must be a superuser or have the special CRE‐
       ATEDB privilege.	 See CREATE USER [create_user(7)].

       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 might have been added
       to template1.

       name   The name of a database to create.

	      The role name of the user who will  own  the  new	 database,  or
	      DEFAULT  to use the default (namely, the user executing the com‐
	      mand). To create a database owned by another role, you must be a
	      direct or indirect member of that role, or be a superuser.

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

	      Character set encoding to use in the  new	 database.  Specify  a
	      string constant (e.g., 'SQL_ASCII'), or an integer encoding num‐
	      ber, or DEFAULT to use the default encoding (namely, the	encod‐
	      ing  of  the template database). The character sets supported by
	      the PostgreSQL server are described in in the documentation. See
	      below for additional restrictions.

	      Collation	 order	(LC_COLLATE) to use in the new database.  This
	      affects the sort order applied to strings, e.g. in queries  with
	      ORDER  BY, as well as the order used in indexes on text columns.
	      The default is to use the collation order of the template	 data‐
	      base.  See below for additional restrictions.

	      Character	 classification (LC_CTYPE) to use in the new database.
	      This affects the categorization of characters, e.g. lower, upper
	      and digit. The default is to use the character classification of
	      the template database. See below for additional restrictions.

	      The name of the tablespace that will be associated with the  new
	      database,	 or DEFAULT to use the template database's tablespace.
	      This tablespace will be the default tablespace used for  objects
	      created	in   this   database.	See  CREATE  TABLESPACE	 [cre‐
	      ate_tablespace(7)] for more information.

	      How many concurrent connections can be made to this database. -1
	      (the default) means no limit.

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

       CREATE DATABASE cannot be executed inside a transaction block.

       Errors along the line of ``could not  initialize	 database  directory''
       are  most likely related to insufficient permissions on the data direc‐
       tory, a full disk, or other file system problems.

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

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

       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.  The principal limitation
       is that no other sessions can be connected  to  the  template  database
       while  it  is being copied. CREATE DATABASE will fail if any other con‐
       nection exists when it starts; otherwise, new connections to  the  tem‐
       plate  database are locked out until CREATE DATABASE completes.	See in
       the documentation for more information.

       The character set encoding specified for the new database must be  com‐
       patible	with  the chosen locale settings (LC_COLLATE and LC_CTYPE). If
       the locale is  C	 (or  equivalently  POSIX),  then  all	encodings  are
       allowed,	 but for other locale settings there is only one encoding that
       will work properly.  (On Windows, however, UTF-8 encoding can  be  used
       with  any  locale.)   CREATE  DATABASE will allow superusers to specify
       SQL_ASCII encoding regardless of the locale settings, but  this	choice
       is  deprecated  and may result in misbehavior of character-string func‐
       tions if data that is not encoding-compatible with the locale is stored
       in the database.

       The encoding and locale settings must match those of the template data‐
       base, except when template0 is used as template. This is because	 other
       databases  might	 contain data that does not match the specified encod‐
       ing, or might contain  indexes  whose  sort  ordering  is  affected  by
       LC_COLLATE  and	LC_CTYPE. Copying such data would result in a database
       that is corrupt according to the new settings.  template0, however,  is
       known to not contain any data or indexes that would be affected.

       The  CONNECTION LIMIT option is only enforced approximately; if two new
       sessions start at about the same time when just one connection ``slot''
       remains for the database, it is possible that both will fail. Also, the
       limit is not enforced against superusers.

       To create a new database:

       CREATE DATABASE lusiadas;

       To create a database sales  owned  by  user  salesapp  with  a  default
       tablespace of salesspace:

       CREATE DATABASE sales OWNER salesapp TABLESPACE salesspace;

       To create a database music which supports the ISO-8859-1 character set:


       In  this	 example, the TEMPLATE template0 clause would only be required
       if template1's encoding is not ISO-8859-1.  Note that changing encoding
       might require selecting new LC_COLLATE and LC_CTYPE settings as well.

       There  is  no  CREATE DATABASE statement in the SQL standard. Databases
       are equivalent to catalogs, whose creation is implementation-defined.
