I would like to propose extending composite types with constraints. Currently there is a preliminar patch for not null constraints. 

===
Changes : 
  -Use the parser from create table to get the constraints 'OptTableElementList' instead of 'OptTableFuncElementList'.
  - Add a new transformation transformCompositeTypeStmt similar to transformCreateStmt to add constraint informations to stmt.
   - Implement a recursive notnull check  when a type is composite 
==
Features enabled :
 - Enable not null in parser for 
create type tyname AS (  a  type NOT NULL )
 - Check for null in rowtypes 

===
