ALTER SCHEMA — change the definition of a schema
ALTER SCHEMAnameRENAME TOnew_nameALTER SCHEMAnameOWNER TO {new_owner| CURRENT_ROLE | CURRENT_USER | SESSION_USER }
   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.)
  
nameThe 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_ownerThe new owner of the schema.
   There is no ALTER SCHEMA statement in the SQL
   standard.
