NAME
       CREATE SCHEMA - define a new schema

SYNOPSIS
       CREATE SCHEMA schemaname [ AUTHORIZATION username ] [ schema_element [ ... ] ]
       CREATE SCHEMA AUTHORIZATION username [ schema_element [ ... ] ]

   INPUTS
       schemaname
	      The  name  of  a schema to be created. If this is omitted, the user name is used as
	      the schema name.

       username
	      The name of the user who will own the schema. If omitted, defaults to the user exe-
	      cuting  the  command.  Only superusers may create schemas owned by users other than
	      themselves.

       schema_element
	      An SQL statement defining an object to be created within	the  schema.   Currently,
	      only  CREATE  TABLE,  CREATE  VIEW, and GRANT are accepted as clauses within CREATE
	      SCHEMA. Other kinds of objects may be created in separate commands after the schema
	      is created.

   OUTPUTS
       CREATE SCHEMA
	      Message returned if the command is successful.

       ERROR: namespace "schemaname" already exists
	      If the schema specified already exists.

DESCRIPTION
       CREATE  SCHEMA will enter a new schema into the current database.  The schema name must be
       distinct from the name of any existing schema in the current database.

       A schema is essentially a namespace: it contains named objects (tables, data types,  func-
       tions,  and  operators) whose names may duplicate those of other objects existing in other
       schemas. Named objects are accessed either by ``qualifying'' their names with  the  schema
       name as a prefix, or by setting a search path that includes the desired schema(s).

       Optionally, CREATE SCHEMA can include subcommands to create objects within the new schema.
       The subcommands are treated essentially the same as separate commands issued after  creat-
       ing  the  schema, except that if the AUTHORIZATION clause is used, all the created objects
       will be owned by that user.

   NOTES
       To create a schema, the invoking user must have CREATE privilege for the current database.
       (Of course, superusers bypass this check.)

       Use DROP SCHEMA to remove a schema.

EXAMPLES
       Create a schema:

       CREATE SCHEMA myschema;

       Create a schema for user joe --- the schema will also be named joe:

       CREATE SCHEMA AUTHORIZATION joe;

       Create a schema and create a table and view within it:

       CREATE SCHEMA hollywood
	   CREATE TABLE films (title text, release date, awards text[])
	   CREATE VIEW winners AS
	       SELECT title, release FROM films WHERE awards IS NOT NULL;

       Notice that the individual subcommands do not end with semicolons.

       The following is an equivalent way of accomplishing the same result:

       CREATE SCHEMA hollywood;
       CREATE TABLE hollywood.films (title text, release date, awards text[]);
       CREATE VIEW hollywood.winners AS
	   SELECT title, release FROM hollywood.films WHERE awards IS NOT NULL;

COMPATIBILITY
   SQL92
       SQL92  allows  a DEFAULT CHARACTER SET clause in CREATE SCHEMA, as well as more subcommand
       types than are presently accepted by PostgreSQL.

       SQL92 specifies that the subcommands in CREATE SCHEMA may appear in any order. The present
       PostgreSQL  implementation does not handle all cases of forward references in subcommands;
       it may sometimes be necessary to reorder the subcommands to avoid forward references.

       In SQL92, the owner of a schema always owns all	objects  within  it.   PostgreSQL  allows
       schemas	to  contain  objects  owned by users other than the schema owner. This can happen
       only if the schema owner grants CREATE rights on his schema to someone else.
