## NAME
       ALTER_SCHEMA - change the definition of a schema

## SYNOPSIS
       ALTER SCHEMA _name_ RENAME TO _new_name_
       ALTER SCHEMA _name_ OWNER TO { _new_owner_ | CURRENT_ROLE | CURRENT_USER | SESSION_USER }

## DESCRIPTION
       **ALTER SCHEMA **changes the definition of a schema.

       You must own the schema to use **ALTER SCHEMA**. To rename a schema you must also have the CREATE
       privilege for the database. To alter the owner, you must be able to SET ROLE to the new
       owning role, and that role must have the CREATE privilege for the database. (Note that
       superusers have all these privileges automatically.)

## PARAMETERS
       _name_
           The name of an existing schema.

       _new_name_
           The new name of the schema. The new name cannot begin with pg_, as such names are
           reserved for system schemas.

       _new_owner_
           The new owner of the schema.

## COMPATIBILITY
       There is no **ALTER SCHEMA **statement in the SQL standard.
