NAME

       CREATE DATABASE - create a new database

SYNOPSIS

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

DESCRIPTION

       CREATE DATABASE creates a new PostgreSQL database.

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

       Normally,  the  creator	becomes  the  owner of the new database.  Superusers can create databases owned by other users, by 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.

       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.

PARAMETERS

       name   The name of a database to create.

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

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

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

       lc_collate
	      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 database.  See
	      below for additional restrictions.

       lc_ctype
	      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.

       tablespace
	      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  [create_tablespace(7)]
	      for more information.

       connlimit
	      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.

NOTES

       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 connection 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 compatible 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 database, except when template0 is used as template. This is because
       other databases might contain data that does not match the specified encoding, 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.

EXAMPLES

       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:

       CREATE DATABASE music ENCODING 'LATIN1' TEMPLATE template0;

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

COMPATIBILITY

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