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 executing 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, functions, 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 creating 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.
